Evaluating the economic ripple effects of optimum gas utilization in Nigeria.
Nigerian Natural Gas Trends
Over the years Nigeria has grown in its natural gas utilization. In 1970, 98.6% of gas
produced was flared, and only 1.4% was utilized as gas injection or for power
generation (IISD, 2008). However in 2010, 581 Bcf of gas flared of the 2,392 Bcf
produced (EIA, 2012), which implies 76% of the gas produced in that year was
utilized. The table below shows country’s gas production rate and depicts the increase
in utilization of gas.

Gas utilization infrastructure
Driven by the desire to create more wealth and diversity in the Nigerian economy, the
government has embarked on a number of gas utilization projects to achieve the
above figures. Also under pressure from environmental agencies and rising domestic
need, the government has put in place facilities, infrastructures, and legislature to
ensure the sustainable development of the NG sector. One of the first facilities built
by the government to utilize gas was the Delta-Ughelli Thermal Power Plant located
at Ughelli, Delta State. It was commissioned in 1966, to generate electricity and with
a capacity of 942 MWe (Global Energy Observatory, 2011)
Since the Delta-Ughelli Power plant, other gas to power plants have been built in the
bid to optimize the natural gas resource. The table below shows a list of Gas to Power
plants and with only a few operating at full capacity.

Nigerian LNG Company: Nigeria’s first LNG facility was incorporated as a limited
liability company on May 17, 1989 and is a joint venture between the Nigeria
National Petroleum Corporation (49%), Shell (25.6%), Total (15%) and Eni (10.4%)
(Ukpohor 2009). Its aim is to harness Nigeria's vast natural gas resources and produce
Liquefied Natural Gas (LNG) and Natural Gas Liquids (NGLs) for export and
domestic use. Located on Bonny Island, NLNG has six trains in operation. Trains 1
and 2 were completed in February 2000 and August 1999 respectively. Train 3 began
operation in November 2002, Train 4 in November 2005, Train 5 in February 2006
and Train 6 in 2007. The current capacity of the six operating trains is some 22
million tonnes per annum of LNG and 4 million tonnes per annum of LPG, from a
feedgas of over 3.5Bcf/d at full production (NLNG 2012). Thus far the Nigeria has
received a total of $9 billion as dividends from the company (YISHAU 2012).
West Africa Gas Pipeline: The effort to increase gas utilization by the Nigerian Gas
Industry includes a regional market involvement. The West Africa Gas Pipeline
project was established in 1982 aimed at capturing the regional market of countries
within the Western African coast. The project originated from a proposal put forward
by the Economic Community of West Africa States to have a NG pipeline pass
through West Africa. After being deemed commercially viable by feasibility reports, a
Memorandum of Understanding on the project was signed by four countries on
August 1999 (Ukpohor 2009). The pipeline is to expand over a distance of 681km,
starting from the Lagos terminal (Nigeria) to three delivery points near, Cotonou
(Benin), Lome (Togo) and Tema (Ghana). The West Africa Gas Pipeline Company
Limited was set up by the four countries as a public-private partnership, to build, own
and operate the pipeline. The shareholders stakes are Chevron-Texaco West Africa
Gas Pipeline Ltd (36.7%), Nigeria National Petroleum Corporation (25%), Royal
Dutch Shell (18%), Volta River Authority of Ghana (16.3%), Societe Togolaise de
Gaz (2%), and Societe Beninoise de Gaz (2%) (Ukpohor 2009). Construction of the
West African Gas Pipeline (WAGP) began in January 2005 with commissioning
occurring in early 2011 (Shell 2011). “The WAPCo pipeline is seen today by
Economists as a catalyst for clean economic growth, a tool for environmental benefit,
and a cornerstone for regional integration.” (Ukpohor 2009).

Gas Exports
Gas exportation was non-existent prior to 1999, when the Nigerian Liquefied Natural
Gas Company came on stream and exported its first cargo in October of 1999
(NLNG, 2012). Table 3 below shows the yearly exports of natural since 1999.

Through these developments Nigeria has become one of the world’s leaders in LNG
exports. According to the CIA’s The World Factbook (2012), it estimated Nigeria
ranked 11th in the world when it comes to natural gas exports in 2011.
Domestic gas trend in Nigeria
The domestic gas market has always been limited by the inadequacy of the gas
transmission and distribution infrastructures (Centre for Energy Economics 2005).
This has evidently slowed the growth of the domestic market in the past. However,
according to a study done by the International Institute for Sustainable Development
(2008), they described the domestic use of NG in Nigeria to have experienced a
quantum jump. This jump was propelled by the increase in options for NG gas
utilization.
Despite this jump it is the opinion of a few (Sawyerr et. al. 20011) that gas utilization
is still very low and has also attributed this to poor infrastructure and the market
availability. The figure and table below show a graphical and detailed description of
the nation’s consumption levels.

Gas Legislation and Policies
Various regulations apply to the sector. For instance the Petroleum Act (PA)
considers ‘natural gas’ under ‘petroleum’ therefore the act applies to the gas sector as
well (Okorie, 2010). Other general regulations overseeing the gas sector include the
Petroleum Profit Tax Act (PPTA), which regulates taxation at the upstream section
and the CITA which regulates taxation at the downstream section. The Oil Pipelines
Act and the Oil and Gas Pipeline Regulation regulate all oil and gas pipelines. The
Department of Gas and the Ministry of Environment are in charge of issuing pipeline
construction permits. However, listed below are the legislations that cover the gas
sector specifically.
The Petroleum Regulation Decree: According to the decree, a lessee or licensee was
obligated to submit a feasibility study or a proposal on their gas utilization prospects
no later than 5 years after commencement of production (Okorie 2010). This decree
was active before 1970 up until 1979.
The Associated Gas Re-injection Act: This act was put in place in 1979 and required
all companies to submit a plan on gas utilization and gas re-injection by 1980. By this
legislation no company was to flare gas after January 1984, with a penalty put in place
for gas flaring (Okorie 2010). Re-adjustments were made to the Act when companies
complained of the penalties being too severe. The final Act came into force in 1984
with lesser penalties.
8 | P a g e
The Nigerian Liquefied Natural gas Decree: The government made provisions for
certain fiscal incentives such as tax holidays, guarantees and assurances to encourage
the utilization of associated gas as LNG (CMD 2012).
The Associated Gas-Frame work Agreement: Cognizant of the amount of revenue
loss associated with flaring and the desire to encourage investment, the government
set up this agreement as a fiscal incentive for gas utilization. The agreement was
introduced in 1992 and includes the following incentives:
- Tax holiday for three years
- All investments necessary to separate oil from gas from reserves into suitable
production is considered as part of the oil field development.
In 1998 additional incentives were offered with the aim of increasing the economic
utilization of gas. They include;
- Gas projects taxes at 30% vs. 85% for oil projects
- Capital expenditures for gas projects chargeable under Petroleum Profits Tax
- Tax holiday of 5 to 7 years
- Exemption on custom duties and VAT on gas related development equipment
- Investment capital allowance of 15%
- Interest deductibility on loans
- Dividends during tax holiday are tax free.
Cyril Odu, vice chairman, Mobil Producing Nigeria Unlimited, stated at the Nigerian
Association of Petroleum Explorationists conference, “That the way to get
investments into the gas industry was to give incentives rather than use penalties to
drive it.” (Ayankola 2008). In view of this statement one may conclude that the above
listed incentives are enough encouragement for investments in the sector by interested
parties.
The Gas Master Plan: The gas master plan under the National Gas Policy 2008 is a
downstream gas policy focused on encouraging the private sector’s involvement in
the commercialization of the country’s natural gas industry (Okorie 2010). Its key
objectives are:
9 | P a g e
1. Maximising the multiplier effect of gas in the domestic economy
2. Optimizing Nigeria’s share and competitiveness in high value export markets
3. Assure the long term energy (gas) security for Nigeria
The Gas Master Plan comprises of the National Domestic Gas supply, the Pricing
Policy and Regulations and the Gas Infrastructure Blueprint.
The issue of domestic supply is addressed through the Domestic Gas Supply
Obligation. The Domestic Supply Obligation is the first major attempt to refocus the
gas resource for domestic use in Nigeria. Through this obligation the government
insures adequate gas resources are dedicated for the rapid domestic industrialization
(Onyeukwu 2009).
The Pricing Policy adopts a pricing framework which categorizes the demand sector
into three strategic sectors, then applies individual prices to the respective sectors
(Onyeukwu 2009). It dictates only floor prices while the actual prices are negotiated.
The strategic sectors are namely: the Domestic sector such as the power sector, the
Industrial sector comprising of industries that use gas as feedstock, and the
Commercial sector which refers to users of gas as industrial fuel such as
manufacturing companies.
Present State of Gas Sector
In a newsletter written by Sawyerr et. al. (2011) on Nigerian gas reserves, the shortfall
in electricity supply and the apparent case of under utilization, they mentioned that
over time Nigeria has come to be seen as a gas province with drops of oil in it. This
conclusion may have arrived due to the fact that Nigeria has a proven gas reserve of
about 180.5 Tcf (BP Statistical review, 2012 and EIA, 2012), and the Nigerian
National Petroleum Corporation (NNPC), the country’s national oil company,
estimating that its gas reserve could reach about 600Tcf in 15 years with the
commencement of focused gas exploration processes (Sawyerr et. al., 2011).
10 | P a g e
“This is why natural gas is envisaged as the fuel to power Nigeria’s economy”,
(Sawyerr, 2011). Experts estimate the country’s gas life expectancy at over 100 years
at its current proven gas reserve. With the commencement and eventual finding of
more reserves, Nigeria is set to be a world energy power if it utilizes this natural
resource.
Nigeria has about 40% of its total proved gas reserves identified as stranded gas caps,
meaning they are not available in the short term. In addition, non-associated gas
constitutes a vast majority of the reserves that are available in the short-medium term
(Odumugbo, 2010) – is this part necessary?
By harnessing its natural gas reserves, Nigeria could alone provide the energy needs
for the West Africa sub-region (Sawyerr, 2011).
Gas Utilization projects
The nation’s gas commercialization agenda involves gas utilization through gas
facilities and transmission and distribution projects. Described below are the current
gas utilization projects operating and under construction.
NLNG Train 7: The NLNG is set to make its Final investment Decision (FID) on its
Train 7, according to NNPC’s Group Managing Director, Austen Oniwon (YISHAU
2012). The Train 7 will bring in an estimated $8 million in Foreign Direct Investment
(FDI) as well as help reduce gas flaring, and improve the country’s revenue profile.
The country also stands to reap an additional $2.2 billion annual dividend (YISHAU
2012). The additional train 7 will increase NLNG’s production to 30 MTPA.
Brass River LNG: The Brass LNG is a $3.5 billion project located between Ogun and
Ondo States. The shareholder structure of the plant is as follows; NNPC 49%, Eni,
17%, Conoco Phillips, 17 % and Total, 17 % (Ukpohor 2009). According to the
Group Manager of NNPC the FID for the Brass will be ready by the year’s end
(Vanguard 2012). Brass LNG is designed to have two trains each nominally sized at 5
MTPA , facilities for liquefied butane and propane extraction, segregation, and
treatment, two 110,000 cm LPG storage tanks, two 185,000 cm LNG storage tanks,
11 | P a g e
one 500,000-barrel capacity NGL tank, marine facilities for the products export and
accommodation for plant operators (Ukpohor 2009).
Olokola LNG (OK LNG) project: The plant is located at the western axis of the Niger
Delta and will cost over $7 billion. It has been designed with an initial capacity of
11mtpa and is funded through a joint venture whereby the Nigerian government holds
49.5 % stake, Royal Dutch Shell, 18.5 %, Chevron, 18.5 % and the British Gas Group
13.5 % (Ukpohor 2009). OK-LNG at completion will have four trains with a capacity
of 22m t/y and the complex will also produce about 300,000 b/d of LPG and
condensate (Ukpohor 2009). Former Head of State Chief Ernest Shonekan during a
visit to NLNG said the FID for OK LNG will be ready in 2014 (NLNG 2012). Shell
Global Solutions International, SGSI, a world leader in LNG technology, marketing
and investment consultancy have said, “The OKLNG has good fundamentals capable
of taking advantage of world LNG market opportunities in year 2018, but only if it
proceeds rapidly to the implementation stage.” (Vanguard 2012)
Escravos Gas to Liquids (GTL) project: A Chevron-operated project currently
underway and at over 70% completions stage (Bala-Gbogbo, 2011). The project is a
joint venture with NNPC and South Africa's Sasol and began in 2008 costing $1.7
billion (Ukpohor 2009). The facility has the capability to refine natural gas to
produce 33,000 barrels per day of fuels from converting over 300million cubic feet of
natural gas a day. Fuel products will include Diesel – 75%, Naphtha – 20%, LPG –
5% (Usman, 2007). Escravos GTL has faced multiple delays and cost adjustments
but is scheduled to be operational by 2013 (EIA, 2011). It is expected to begin
production in 2013 (Chevron 2012).
The Trans-Saharan Gas Pipeline (TSGP): On July 3, 2009, Nigeria, Algeria, and
Niger signed an agreement to create the TSGP. This is a proposed natural gas pipeline
from Nigeria, passing through Niger to Algeria. The pipeline is designed to supply
gas to Europe by connecting to the existing Trans-Mediterranean, Maghreb-Europe,
Medgaz and Galsi pipelines across the Mediterranean coast (Conan 2011). The
pipeline will cover roughly 1,037 kilometres (604 miles) in Nigeria, 853 kilometres
(530 miles) in Niger, and 2,310 kilometres (1,435 miles) in Algeria, an estimated total
12 | P a g e
of 4,200 kilometres (2,609 miles) (Conan 2011).. The project is estimated at a cost of
$13 billion: $10 billion for the pipeline, and $3 billion for the gas collecting and
Nigerian infrastructure (Conan 2011). Once in full operation the TSGP is expected to
reach a capacity of 1,059 Bcf/year. The following factors support the necessity and
viability of this cross border project
Depletion of European gas fields
Demand for energy in Europe is likely to remain high
Uncertainty over the feasibility of shale-gas production in Europe
The preference for a gas pipeline over liquefied natural gas (LNG) technology
The presence of sufficient Nigerian reserves
The need for an alternative to Russian gas
Nigeria stands to gain political influence through this project. In his article Russia’s
new weapon: the politics of pipelines, Goldman (2009: 1) says, “In particular, Russia
has turned its natural gas into an especially effective weapon. This is because Europe
still is mostly dependent on its pipeline system for its natural gas supplies. This
means that if for some reason Russia curbs its pipeline deliveries, its customers in
Europe have no other option than to agree to whatever Russia may demand.” He goes
on to speak on Europe’s efforts to broaden its gas supply through NABUCCO, a
pipeline from Central Asia. TSGP is viewed also as an alternative gas supply pipeline
and Nigeria can exploit this pipeline for its political gains.

Gas distribution projects
For the country to receive the needed gas resource, gas distribution pipelines need to
be put in place to deliver gas round the nation. NNPC through NGC has began
developing several domestic pipelines in order to meet the growing domestic demand.
According to a report written by the International Institute for Sustainable
Development (2008), the NGC have implemented several gas supply systems with a
collective throughput of 2.5 Bcf/d, over 1800 km of gas gathering and transmission
lines as well as 14 compressor stations. The table below provides information on
existing major gas transmission pipeline in Nigeria.

Nigerian Gas Company (NGC) currently has 30 firms in the Agbara/Ota industrial
area of Ogun State connected to gas supplies via eight of its operating gas supply
systems. The current plant capacity is 2 Bcf/d (Odumugbo 2010).
Already benefiting from the gas transmission lines is the Greater Lagos Industrial
Area (GLIA). The project is phased into Ikeja 1A, Ikeja 1B and the Greater Lagos II.
The entire project covers an estimated 146.2 km. Already over 38 companies are
16 | P a g e
connected to the transmission line with another 125 customers awaiting to be
connected (Oando 2012).
Figure 5: Gaslink distribution networkSource: Oando Plc 2012
In order to meet up to the demand, three major gas transmission systems are to being
developed; the Western System comprising the existing Escravos Lagos Pipeline
System (ELPS) and an additional offshore extension to Lagos, the South-North gas
transmission pipeline, the inter-connector which will link Eastern gas reserves to the
17 | P a g e
other two transmission systems (Sawyerr 2011). The South –North gas transmission
pipeline consists of 48 inch pipeline, from Akwa Ibom/Calabar to Ajaokuta to Abuja
to Kano, Kaduna and Katsina. It also connects the Eastern states of Anambra, Abia,
Ebonyi, Enugu and Imo. The overall pipeline system will cover an estimated distance
of 1000km and is expected to cost $1.3 billion (Pipelines International 2010).
Summary of gas projects – should I do this?
Regulation and legislation
The Downstream Gas Bill seeks to institute a separate legal and regulatory framework
for the Downstream Gas sector for the purpose of achieving a more effective
regulation (uche 2011)
PIB law - The law is designed to introduce a new regulatory framework that will
provide for separate regulation of the upstream and downstream as their activities are
different. If the PIB becomes law, a regulatory authority, a gas transportation
company and a gas marketing company are expected to emerge.
Incentives– should I do this?
Impediments to the Growth of the Domestic Natural Gas Sector
Although the Gas Master plan set by the government is to increase multiplier effect in
the domestic economy, the plan is hinged on harnessing of the country’s abundant gas
resource. Therefore the first impediment will be gas supply. Gas supply is governed
by the practical issues of linking the upstream (exploration) and downstream
(distribution and marketing) activities. In a study done by Humphrey (2009), he
classified the supply challenge issues into Availability, Affordability and
Commerciality of supply, Deliverability and its cost effectiveness, Legal and
regulatory framework and Funding issues.
The Nigerian gas market is controlled by few major IOCs with a natural favouritism
for the export market and this creates a major conflict and potential resistance to gas
supply to the domestic market (Humphrey 2009). The table below shows the strong
portfolio interest of the major IOCs towards exporting gas.
