CAG wants TPDF to take over oil and gas security

images
Oil and gas exploration companies operating in the country pay foreign private security companies US$3 million (about over 6bn/-) annually, which the Controller and Auditor General (CAG) says was improper.
 
CAG Prof Mussa Assad said the money could be put into proper use if it was paid to Tanzania People’s Defense Forces (TPDF). 
 
The national army, he said last week in Dar es Salaam, was mandated to deal with all the security of the country, including oil and gas drilling rigs. 
 
According to him, that made it relevant for TPDF to qualify for the security consultancy fees currently paid to foreign firms, he explained.
 
Prof Assad said the move would also help support the local content policy for the oil and gas industry which is currently dominated by foreign operators.
 
He gave this outlook last week at the launch of Tanzania Oil and Gas Almanac. He said the involvement of TPDF would as well help save foreign exchange, which is currently repatriated by the security firms.
 
“I am sure that if the US$3 million could be paid to the army, it will be well spent to improve security of our natural resources,” Prof Assad argued. 
 
He pointed out that before the discovery of oil and gas, Tanzania already had gold and diamond, whose mining continues to be undertaken by foreigners. Unfortunately, he argued, the country was yet to meaningfully benefit from the two minerals.
 
He said good governance was vital for these resources to benefit the whole country. He added that the launch of the almanac, which constitutes transparency tools, sought to boost transparency in the extractive industry.
 
Tanzania is poised to become as gas economy after discovery of more than 55 trillion cubic feet of natural gas.

Citizens of Tanzania Support Extracting and Selling of Natural gas Internationally

A new poll from across the country shows that citizens oppose using gas as collateral for government borrowing. Released in Dar es salaam recently the study dubbed, ‘How Tanzania should use its natural gas citizens’ views from a nationwide deliberative poll’ shows more citizens support extracting and selling the country’s natural gas internationally to raise revenue, rather than directly financing domestic electricity generation.

It shows that Tanzanians nominally support ‘strict limits’ on spending gas revenue and oppose using gas as collateral for government borrowing. The study, done by Research for Poverty Alleviation (REPOA) and Center for global Development between 2014 and July 2015, also shows that most Tanzanians support both publishing all gas contracts and a role for international oversight of how the government uses gas revenues.

Most respondents also supported the idea of direct distribution of resource revenues to households in principle.But when offered a choice between cash transfers and government programmes, most Tanzanians prefer that gas revenue be spent on government programmes rather than cash transfers, according to the report. REPOA’s Executive Director Prof Chacha Wangwe said some 2,000 people from 20 districts were interviewed, including ordinary and policy makers and the findings highlighted that majority don’t want the government to borrow ahead of time.

“They want transparency. They want monies from oil and gas to largely go to education and health,”he said A stakeholder at the report’s launch, prof Ibrahim Lipumba said that the findings show that the ordinary people have an understanding of what the resource should do for the country, especially where they highlighted an importance for transparency.

New natural resource discoveries, oil and gas provides substantial opportunity to fast-track human development progress, with updated estimates indicating that revenues to be developed could contribute between 9 per cent and 31 per cent of additional government revenues.

The tools and evidence presented are intended to empower the government with newly discovered extractives resources, by helping it to grapple with the complex chain of policy decisions that will be key to transforming new resources into stronger human development outcomes – ranging from public sector spending allocations to leveraging industry spending. Such findings are timely since President Jakaya Kikwete recently took major step towards ensuring fiscal and economic stability by signing legislation that will help ensure revenue from natural gas discoveries bring socioeconomic progress for citizens.

These recent gas discoveries have the potential to bring in as much as 1.4 billion Dollars per year to Tanzania — more than 10 per cent of current government revenues–within the next decade.

The new revenues could help provide basic needs for citizens such as improved primary healthcare and access to quality education. The next step for the government will be to develop detailed regulations and procedures to implement the new laws.

The new administration will face policy decisions on how to manage and allocate resources in a responsible way and in accordance with the laws. Maintaining a focus on human development goals, transparency and ensuring public awareness and debate with key stakeholders and citizens will be crucial.

 
 
 

A new study by the African Development Bank and the Bill & Melinda Gates Foundation shows that despite recent drops in commodity prices, revenues from recently discovered oil, gas, and mineral reserves in countries such as Ghana, Liberia, Mozambique, Sierra Leone, Tanzania, and Uganda could add between 9 per cent and 31 per cent to those governments’ revenues. The report, which was launched in Dar es Salaam in early September.

Provides updated projections on the timing and magnitude of these natural resource revenues and guidance on how to effectively direct them toward strengthening health, education, and other social services. Supporting long-term economic growth. In Ghana, for example an estimated one-third of the country’s combined health and education needs over the next decade could be funded from recent oil discoveries.

In Liberia, Mozambique, and Sierra Leone, revenues from recent natural resource discoveries could meet half of health funding needs. The potential opportunities in Tanzania and Uganda are also significant. In this context, African leaders have a valuable opportunity to work with the private sector and civil society to develop long-term plans that link new natural resource revenues with human development goals.

Such plans should be anchored in realistic expectations about the timing and magnitude of new revenues and avoid borrowing against future earnings–a tactic that could easily backfire due to the volatility of oil and gas prices.

At the same time, African countries need to devote resources to prepare for the global transition from fossil fuels to fight climate change. This process is of particular urgency for Sub-Saharan Africa, a region that combines large reserves of oil and gas with a high risk of suffering from large-scale disruptions in temperature and rainfall. The release of the AfDB- Gates Foundation report and the signing of the new legislation in Tanzania have come at a pivotal moment.

 

In September, global leaders from nearly 200 countries will meet at the United Nations in New York to adopt the UN Sustainable Development Goals (SDGs). A central issue for this 15- year global anti-poverty and development agenda is how African countries will help provide the financing needed to meet the basic needs of their people. New natural resource revenues could be a meaningful source of this funding–if they are effectively and responsibly managed.

History is replete with examples of countries that have squandered their natural resource wealth through mismanagement of revenues, inability to harness privatesector investment, and other grave missteps, including human rights violations and environmental degradation.

But some countries–such as Indonesia (with oil) and Chile and Botswana (with mining)–have successfully applied these revenues to stimulate job creation, economic diversification, and expand social services. When policymakers, donors, technical partners, and private companies work together to develop the necessary policies and support smart planning and rigorous management, entire nations can benefit from expanded opportunity and growth.

Tanzania has achieved a commendable milestone but there is more to be done. Through good management principles, we hope that the new legislation will turn into a legacy of good natural resource management that can be followed by other African countries in the months and years to come.

How oil & Gas professionals who Lost jobs Can Survive the Low Oil Price

 

 

1023077-6-20150912224924-oil-workers-suffering-from-job-losses-as-result-of-low-oil-prices

 

Since falling of oil price in  June 2014  many oil and gas professionals have lost their jobs in petroleum companies.

It is true that Petroleum professionals who lost their jobs in petroleum companies experiencing bad time, this pushes them divert into different industries, sometimes even not related to their experience or field of study, Some  of them spending time at home doing nothing rather than killing time to wait for oil price to recover.

If you are among of them, don’t panic, today I will show you how you can survive during this period of oil price crash. But before i figure out how you can survive, I want you to keep in mind that, this is not the first time oil

This is not the first time oil and gas industry downturn

Remember the similar oil price crash has occurred in 1986, also remember oil price crash has occurred in 2008, so you have to keep in mind that this is not the first time for oil price crash to occur, and also is not the last oil price crush, i predict another crash may exist again. If you know all of this you will realize that this is normal circumstance in oil and gas business.

Now Lets see how you can survive in this period of low crude price

1.Diversify

To be employed in petroleum companies does not imply you  unable to work  in other companies unrelated to oil and gas. So this is the right time to   mindstorming and decide where you can work. Also you can learn others skills  or disciplines that can help you while waiting for market to recover.

 

  1. Volunteer.

One of the advantages of oil prices crash is it develop leadership skills and it boost your resume, So  go and volunteer to any institution, don’t underestimate any  volunteering activities just go and learn then chance will go back to you.

 

3. Get  updated with current issues in petroleum industry.

Know where layoff are happened, know the trend of layoffs in petroleum industry, also  you must which sector are still recruit and which segment are not, and this you can know by visiting sites like    tanzaniapetroleum.com etc

 

4.Get job that you will support you to make living.

It doesn’t matter where as long you get money, find where you can add value and this will help you increase chances of getting job later.

 

5.Widen your network.

This is not only will help you to get job but also it’s very important for your career development and success. Such for key people in the internet, use social networks wisely and the one I recommend most is to create professional linkedin profile. Attend events and conference relating to petroleum industry.

FINAL WORDS

It’s difficult to predict when this downturn will end up  but atleast at the end of 2015. So is up to you how to react to  that. If petroleum industry is your passion I believe you will fight and win the battle. But before  that happen  I believe a lot of thing should be done. This is right time to start. Start now…….

 

 

 

 

 

Iss Awarded Paragon Offshore Project In Tanzania

 

 

Paragon-Offshore-hires-ISS-for-logistics-in-Tanzania-320x180

Inchcape Shipping Services (ISS) has been appointed by Paragon Offshore in Houston as marine and logistic services provider for a new drilling campaign off the Songo Songo Islands, Tanzania – the first new commercial drilling project in Tanzania in a number of years.

ISS is providing a range of services for Paragon Offshore including full husbandry, crew logistics, visa assistance and arranging marine and air charters.

Paragon Offshore is deploying jack-up rig M826 on the nine month campaign for PanAfrican Energy Tanzania – the country’s first natural gas producer.

M826 arrived at the field on board semi-submersible vessel, OHT Falcon, to be floated off and pinned to the drilling location.

During the campaign, M826 will clear actively producing wells to enhance output and will drill several new wells in the same field

See Why Discovery of Natural gas in Tanzania Could not bring Too Many Jobs To Tanzanians as they believe




Few weeks ago i got  the text from Tanzanian  who
is studying Petroleum engineering in among  of university in China, He was curious to know  about the
employment opportunity in natural gas sector in Tanzania? And this is why  i am writing this article.

You know many people believe the
discovery of natural gas could give Tanzanians millions of job opportunities,
they think, their sons, relatives or themselves can be  employed in 
natural gas industry.This  is definetly  untrue. So to day, this article    will clear up  this 
common misconception
Oil and gas sector is highly capital
intensive industry with risky operations. And Due to the investment of high
capital, the oil companies do not prefer to have a large number of employee in
order  to make reasonable profit. In the currently
findings released by Twaweza organization in a research brief tittled “Great
expectation citizens views on the gas sector” shows that, average citizens
expect four millon job opportunities from natural gas industry. Their expectation
 is beyond of the real situation. Tanzanians can find an example of country like Norway, though of its massive discovery of natural resources,  they  have only 240,000  employee  in their  gas sector. 

You can imagine, Tanzanians expect four millions job in gas sector while Norwagians who currently employed in gas sector is only 240,000. I hope you will agree with me that, the perception of many Tanzanian citizen to get job in gas sector is unrealistic. 
MY FINAL WORDS
 Citizen might be be
employed in this sector, but is not at large number  as many citizens
believe, few people they could get employment and not many of them. This is
the right time for Tanzanians to be aware on this particular matter.

Mnazi Bay Gas Wells Deliver 1st Gas to Tanzania Pipeline

East Africa-focused junior producer Wentworth Resources announced Friday the first gas delivery from its Mnazi Bay Concession in southern Tanzania to the country’s new transnational pipeline.
Wentworth said that two wells are now producing, with the three remaining wells expected to be put on production in the coming months. Initial production volumes will be used for commissioning purposes and to fill the pipeline, with production rates expected to increase to 70 million cubic feet per day by October this year and 80 MMcf/d by the end of 2015.
Wentworth added that the Mnazi Bay joint venture partners have agreed payment security terms with Tanzania Petroleum Development Corporation, the buyer of the gas, and various other parties.
Wentworth Managing Director Geoff Bury commented in a company statement:
“We are very pleased to announce that production from Mnazi Bay has now commenced and the Mnazi Bay joint venture is the first supplier to the new transnational pipeline in Tanzania. Concluding the payment guarantee and starting production in our Mnazi Bay gas fields are pivotal events for Wentworth and underpin the long-term viability of our operations in East Africa and our partnership with Maurel & Prom and TPDC.
“Wentworth is well positioned to become a significant gas producer in Tanzania, where supply and demand dynamics offer an opportunity which we and our partners are uniquely placed to realize. We expect to exit 2015 in a strong financial position.”

The Ministry of Energy & Mineral Development has announced that
the “Uganda International Oil & Gas Summit” (UIOGS) will be held in
Kampala on 16-17 September 2015.

With a first-class conference programme led by Government, Public
Sector and Private Sector industry leaders; the Summit marks an
important point on the global calendar.

UIOGS is held under the Patronage of Eng. Irene Muloni,Minister of
Energy and Mineral Development; and will be used by the Ministry as its
official platform for meeting international companies and presentation
of the multitude of energy projects presently ongoing or planned for in
Uganda.

Uganda has much to offer the global oil and gas community and 2015 is
an exciting year as the country moves towards commercial production.
Uganda is blessed with its natural resources and now has an estimated
6.5 billion barrels of oil in place, a high drilling success rate of
85%, advanced refinery plans, vast acreage of underexplored areas rich
in hydrocarbons and much to look forward to with the new licensing
rounds.

The UOGS programme will provide an invaluable insight into all the major issues, challenges and opportunities including:

  • Focus on the licensing rounds and new opportunities
  • Update on existing fields and exploration success
  • Financial and regulatory frameworks
  • Uganda’s Refinery Project – 60,000 bpd by 2020
  • Move to commercial production
  • Supporting the oil and gas industry through a skilled workforce and local content
  • Infrastructure developments to support oil & gas
  • How can a successful oil industry support our drive towards rural electrification

The Ministry of Energy & Mineral Development will be using the
UIOGS platform to actively engage with allits partners and suppliers
from around the world. The services of the renowned market leaders for
oil & gas conferences; Global Event Partners have been engaged to
work alongside domestic experts Image Care to ensure that UIOGS is a
first-class event that puts Uganda firmly on the global map.

UIOGS is a two day conference that will be held at the Kampala Serena
Hotel on 16-17 September 2015. The programme will be opened by Hon. Eng
Irene Muloni and will feature more than 30 Government officials,
Company leaders and Industry experts gathered from Uganda, the region
and throughout the world to give Uganda a truly global platform.

New petroleum producers survey policy options in wake of oil price slump

Countries seeking to develop newly-discovered petroleum resources are
facing a fall in global oil prices, with competition from the ‘shale
gas revolution’ in the United States, as well as renewable energy
sources.
At a New Petroleum Producers Discussion Group in Tanzania, organised
by Chatham House and co-sponsored by the Commonwealth Secretariat,
authorities from more than 20 countries met this week to find solutions
to these and other shared challenges.
The four-day forum from 30 June to 2 July, at which a set of Guidelines on Good Governance for Emerging Oil and Gas Producers was
released, was attended by government ministries and national oil
companies from Belize, Guyana, Kenya, Mauritius, Mozambique, Jamaica,
Seychelles, Trinidad and Tobago, Tanzania, and Uganda, among other
nations.
“In the midst of the oil crisis there is less capital available for
investment,” commented Michael Mwanda, Chairman of the Tanzania
Petroleum Development Corporation, which hosted the meeting in Dar es
Salaam. “Some projects which were pegged on a high oil price are now
becoming uneconomic and difficult to operate.
“We need to learn from each other and share experiences on how to
reduce costs, operate efficiently and become more competitive,” Mr
Mwanda said.
Addressing the forum, Ekpen Omonbude, Natural Resources Adviser at
the Commonwealth Secretariat, remarked: “This price decline has
necessitated a critical look at strategies to manage petroleum
resources, from development programmes to responsible wealth management,
to ensure benefits for future generations.”
Dr Omonbude stressed that while the slump in the price of oil – from
over US$100 a barrel in 2014 to around US$60 today – presents immediate
challenges, these can be mitigated through the adoption of flexible
fiscal regimes, increased economic diversification, the development of
good governance regimes and revenue transparency.
“Our mission is clear – to help position our member countries to
realise the potential of their resource wealth as a driver of
sustainable development and economic prosperity,” the Commonwealth
representative said.
The New Petroleum Producers Discussion Group was
established in 2012 to help countries think critically about policy
options available either during the first steps of exploration and
development or when restructuring governance arrangements. Options
include setting up regulatory institutions and drafting regulations and
laws that encourage investment, while balancing the needs of society and
environmental protections.
This week marked the first time the discussion group has met outside
London and included a final-day national seminar for representatives of
Tanzania’s oil and gas sector. Co-sponsors of the initiative include the
Natural Resource Governance Institute and the Africa Governance
Initiative.
The Guidelines for Good Governance in Emerging Oil and Gas Producers,
a synthesis of proposals put forward at each discussion group, seek to
guide national authorities to pursue policies which follow good
practices, but which also respond to national contexts.
Dr Valérie Marcel, Associate Fellow at Chatham House, principal
author of the guidelines, said: “The emergence of shale oil and new
renewable technologies offer opportunities and challenges. How the
emerging producer is affected and will respond is what we have been
debating. One of the main issues is how to adjust to a low price
environment, asking what impact is this going to have on licensing terms
and the ambitions of national oil companies.”
She added: “Emerging producers are thirsty to learn from their peers
about what has worked elsewhere and what advice to give. More
established producers want to know whether they are doing things right
and what pitfalls they should avoid. This is a really important learning
process.”
During the forum, participants exchanged experiences on how to
attract investment while preserving long-term national interests,
managing expenditure plans as well as ways to guard against abuses and
fraud in contracts and licensing. Training sessions focused on involving
local suppliers in supply chains, the design of fiscal systems and new
information tools.

Eddy Belle, Chief Executive of PetroSeychelles, the national oil
company of Seychelles, said: “[Petroleum] is a very dynamic business –
there is new technology coming in and new ways of doing things. What
Chatham House is doing with the help of the Commonwealth Secretariat is
getting people together so you have the chance to learn from the
mistakes as well as the successes of others.”
Bashir Hangi, Communications Officer for Uganda’s Petroleum
Exploration and Production Department, commented: “Such a forum helps us
a lot as emerging producers. We peer review ourselves, and our people
go home with a lot of advice. One piece of advice I would share is that
you cannot ignore your stakeholders – civil society, academia and
communities where there are operations. They should not be taken for
granted; they should be brought on board and be involved in the
management of the resource.”
Anthony Paul, Managing Director of the Association of Caribbean
Energy Specialists, said: “Oil and gas resources give opportunities to
deepen industrialisaton, providing power and access to better lighting,
heating and cooking facilities as well as petrochemicals and
fertilisers. There are also benefits from developing the services
industry. What strikes me most is that all countries want the same
thing: they want the resource to benefit their citizens.”

This is How To Drill Oil and Gas Well

          Now, during this lesson, we will see how to drill them.
1. First of all, let’s see how to describe the subsurface characteristics, in order to plan the design of the future well and to define the phases of the drilling job.
2. Then, we’ll describe the drilling system, and how the driller can manage the drilling process safely.
During the exploration phase a well is needed to confirm the presence of oil or gas in the reservoir.
Some appraisal wells are needed for the delineation process.
Moreover, at the end of the reservoir strategy study, a reservoir model defines how to develop the field, and, more particularly, where to drill the wells and the contribution of each of them to the production plateau.
The role of the driller is to build these wells required for the field development.
A well is an expensive item. It must be carefully studied and planned before being drilled. The well preparation phase involves coordinated work between geoscience engineers and drilling/completion engineers.
How to design a well?
In order to set up the drilling program, the driller needs to know the location of the rig, where the well has to enter the reservoir, the trajectory of the well in the reservoir for a good connection between the well and the reservoir, and the formations to be drilled. Let’s detail the description of the subsurface.
For each formation to be drilled, there are 2 characteristics that need to be known accurately:
1. the pore pressure
2. and the fracture pressure.
The pore pressure is the pressure of the fluid within the grains of the rock. It depends on the depth of the formation and on its nature (sandstone, shale, …).
The fracture pressure corresponds to the minimum pressure to be applied on the rock to generate a fracture.
When the formation is drilled, the well is full of a fluid: the drilling mud, which is directly in contact with the rock, and applies a pressure on it: Pmud.
The mud pressure depends on the depth. One of the roles of the mud is to maintain the interstitial fluid within the rock, in order to avoid a kick.

During the drilling process, the mud is in contact with the rock, which contains a fluid within the grains.
A fluid always flows from high pressure to a lower pressure. If the mud pressure is higher than the pore pressure, the formation fluid cannot enter the well. It remains in the formation and there is no risk of blowout.
During the drilling process, the mud is in contact with the rock, which contains a fluid within the grains.
The mud pressure has to be lower than the frac pressure, in order to avoid the rock being fractured. To conclude, keep in mind that the mud has to be designed so that the mud pressure belongs to the interval between the pore pressure and the frac pressure. This interval is called the mud window.
Both Ppore, in red, and Pfrac, in blue, can be plotted on a (pressure/depth) graph.
The mud pressure has to be in the yellow zone, which is called the mud window. For each lithology to be drilled, the mud has to be well adapted to its characteristics. The well is therefore drilled in different phases, each phase corresponding to a new mud to be used.
At the end of a phase, a casing is installed and cemented to protect the well from the formation already drilled and to finalize the well walls.

The definition of each of these phases is called the well design.
A typical well design is as follows:
1. The first tubular is the conductor pipe installed by the civil engineer before the rig
arrives on site.
2. The next phases are drilled using the rotary drilling technique.
3. The surface casing maintains the unconsolidated surface formations and protects the groundwater.
4. The intermediate casing protects the well from the formations or fluid which could prevent the drilling process from continuing.
5. The last casing is the production casing which allows the reservoir to be isolated.
6. During the last phase the well enters the reservoir.
When a well is an exploration well, designing is much more difficult , due to a lack of measurements and information to describe the subsurface. The mud window is not accurately known. Such uncertainties have to be taken into consideration in the drilling process.
When a well has to be drilled in a new region, there are many uncertainties about the data, including that related to the pore and frac pressure profiles. On the contrary, when a development well is planned, it benefits from data from the surrounding wells already drilled. In this case, the pressure profiles are well known, and the uncertainties are lower.
Let’s mention that the trajectory of a well can be vertical, deviated, or horizontal. The choice of the trajectory depends on the location of the rig, the location of the target of the well when it enters the reservoir, and the trajectory of the drain in the reservoir itself. These two last data are defined and given by the reservoir engineer to the driller.

How a well is drilled in practice? Mechanically, a vertical force applied on the drilling bit (the weight on bit), together with a movement of rotation, generates down to the bit the power necessary to destroy the rock. A hook hangs up the drill string, which is composed of several tubulars screwed together, and, at the bottom, there is a drilling bit.
Both the weight on bit and the rotation per minute, which is given by the rotary table located at the rig floor, are controlled by the driller to maximize the rate of penetration of the bit.
Their optimization depends on several parameters, including the kind of rock to be drilled: the regulation of the hook height controls the part of the total weight of the drillstring applied on the bit, the rotation is often given by a rotary table located at the rig floor.
The mud circuit is combined to the mechanical part of the system.
Firstly, the pump sends the mud at high pressure through the discharge line, the stand pipe, the rotary hose and the top drive, into the pipes.
The mud flows in the drill string down to the bit and catches the small pieces of broken rock, the cuttings, to transport them up to the surface in the space between the drill string and the well walls.

At the surface, the cuttings, the sand and the silt are removed from the mud through shale shakers and other systems.
The mud can be sent to the tanks in order to be re-injected.
In order to control the well in case of blowout, a Blow Out Preventer is installed between the top of the well and the rig floor. This BOP stack is composed of an annular BOP and different rams able to close the well in case of emergency. The size of the BOP is adapted to the maximum pressure that can be encountered during the drilling process.
