Nigeria

Country overview

The Federal Republic of Nigeria is located in West Africa. It is bordered by the Republic of Benin in the west, Chad and Cameroon in the east, and Niger in the north. Its coast lies on the Gulf of Guinea and part of the Atlantic Ocean in the south. The people of Nigeria have an extensive history, and archaeological evidence demonstrates that human habitation in the country dates back to at least 9000 BC.
Nigeria is the most densely populated country in Africa and the 9th most densely populated country in the world. It also has one of the fastest growing economies in the world.
Petroleum plays a large role in the Nigerian economy, accounting for 40% of the GDP. It is the 12th largest oil producer in the world, the 8th largest exporter and has the 10th largest proven reserves. The country is also a founding member of OPEC.
Natural resources in the country include iron ore, limestone, lead and zinc. Agricultural products include groundnuts, palm oil, cocoa, coconut, citrus fruits, maize and sugar cane. Nigeria also has a booming leather and textile industry.

Licence Areas

Addax Petroleum began operations in Nigeria in 1998 by signing two Production Sharing Contracts (PSCs) with the Nigerian National Petroleum Corporation (NNPC). Our average annual production was 8,800 barrels per day (bbl/d). Since this acquisition, Addax Petroleum has driven its growth by acquiring oil properties deemed by others to have limited remaining production potential and using its strong in-house technical and operational expertise to grow reserves and production in a cost effective manner.
In Nigeria, Addax Petroleum’s producing assets include 11 field complexes with around 60 production wells in concession OML123, 2 fields with 20 producing wells in concession OML 124 and 2 fields with 14 production wells in concession OML126. Ongoing progress with Field Development Planning is expected to result in a significant increase in our production, from the present combined 75.000 bbl/d from OML123, OML124 and OML126 to over 85.000 bbl/d at the end of 2012.

OML126 100.00 178,300 Addax Petroleum

OML126 and OML137 are two contiguous blocks located 90 km offshore, south of Port Harcourt, in water depths ranging between 50 m and 210 m. Combined, they represent Addax Petroleum’s largest Nigerian properties as measured by area and also account for the majority of the company’s recent production growth. Production from OML126 commenced in March 2005 and averaged 35,000 bbl/d in 2011. OML137 is an exploration and appraisal property. To date there has been no production from, and there are no production facilities on, OML137.

Description

  •  Cover a combined area of approximately 387,800 acres (1,570 km2), 90 km offshore south of Port Harcourt
  • The southern half of OML126 has been completely surveyed by 3D seismic and contains two producing oil fields (Okwori and Nda), four undeveloped oil discoveries and three identified exploration prospects
  • OML137 was surveyed by 3D seismic in early 2006 and contains the Ofrima North oil discovery and several potentially commercial natural gas discoveries (Shokoloko, Toriye, Odum, Asanga and Ofrima), four identified oil prospects (Ofrima North, Atuma, Udele and Asa) and a number of shallow and deep leads
OML137 100.00 209,500 Addax Petroleum

OML126 and OML137 are two contiguous blocks located 90 km offshore, south of Port Harcourt, in water depths ranging between 50 m and 210 m. Combined, they represent Addax Petroleum’s largest Nigerian properties as measured by area and also account for the majority of the company’s recent production growth. Production from OML126 commenced in March 2005 and averaged 42,330 bbl/d in 2008. OML137 is an exploration and appraisal property. To date there has been no production from, and there are no production facilities on, OML137. A field development plan is being prepared for Udele Ofrima black oil development.

Description

  • Cover a combined area of approximately 387,800 acres (1,570 km2), 90 km offshore south of Port Harcourt
  • The southern half of OML126 has been completely surveyed by 3D seismic and contains two producing oil fields (Okwori and Nda), four undeveloped oil discoveries and three identified exploration prospects
  • OML137 was surveyed by 3D seismic in early 2006 and contains the Ofrima North oil discovery and several potentially commercial natural gas discoveries (Shokoloko, Toriye, Odum, Asanga and Ofrima), four identified oil prospects (Ofrima North, Atuma, Udele and Asa) and a number of shallow and deep leads
OPL291 72.50 230,600 Addax Petroleum

Addax Petroleum acquired a 72.5% interest in, and operatorship of, OPL291 in October 2006 from Starcrest Nigeria Energy Limited, who retained the remaining 27.5% interest.  OPL291 is located approximately 130 km off the Nigerian coast in water depths ranging from approximately 1,000 to 2,300 m.  The highly prospective nature of the property is underlined by its proximity to the nearby world-class Agbami oil field in an adjacent block, which is currently under development by Chevron. OPL291 represents the mandatory relinquishment area following conversion of OPL216 to OML127 prior to development of the Agbami field in OML127. OPL291 was tendered by the Nigerian government under the 2006 mini bid round and was originally awarded to Starcrest.
Addax Petroleum acquired approximately 1,500 km2 of 3D seismic over the northern portion of OPL291 in order to further define the Merlin and Emrys prospects as well as to add to the licence area’s prospect inventory.

Description

  • Covers an area of 318,100 acres (1,287 km2) in water depths ranging from 1,000 to 2,300 m
  • OPL291 is immediately adjacent to OML127 (to the north) which contains the Agbami and Ikija fields, operated by Chevron and OPL242 (to the west) operated by Devon Energy Corporation
  • One potentially significant prospects (Odoko) is identifiable from existing 2D and a 3D seismic data covering the majority of the licence area, as well as a number of leads from this data
Okwok 12.00 2,700 Oriental

Okwok is located approximately 45 km off the Nigeria coast, due south of Calabar, in water depths ranging between 35 m and 50 m. Okwok lies within ExxonMobil’s licence area OML67, immediately to the south of OML123, and covers an area of 22,500 acres (91 km2).

Field activities

  • Field discovered in 1967 and partially appraised in 1968 by Mobil
  • Two further wells were drilled in the field, the most recent in 1993, however neither well was production tested
  • Two 3D seismic surveys were acquired over the field (the most recent which was in 2004)
  • Three wells and a sidetrack well drilled by Addax Petroleum in 2006. Two wells were flow tested; the first well test produced at a rate of 400 bbl/d of light 32° API oil; however, the true flow potential of the well was not reached because of sand control problems. The second well test produced at a rate of 1,220 bbl/d of medium 26° API oil. Both wells are currently suspended for potential tie-back to production.
OPL227 40.00 84,100 Express
