Platina is a deepwater oil field located at a water depth of approximately 1,300ft in Block 18, offshore Angola. Block…
Bowleven received approval for its Etinde Exploitation Authorisation Application (EEAA) in May 2014. The field development will begin following approval of the final investment decision (FID). It is expected to be approved in conjunction with the FID for the proposed fertiliser plant of Ferrostaal at Linbe, which will receive dry gas from the project.
EEAA for Etinde provides Bowleven (75%) and its partner Cameroon Offshore Petroleum (CAMOP- 25%) development rights for the fields at block MLHP-7, located within the Etinde permit, for an initial period of 20 years. SNH (Société Nationale des Hydrocarbures), state-owned hydrocarbon company, has an option to claim 20% of the stake in the offshore field.
A wholly owned subsidiary of Bowleven, EurOil acquired the original interest in the Etinde exploration permit in 1998. The Etinde permit comprises Blocks MLHP-5, MLHP-6 and MLHP-7 within Rio Del Rey and Douala Basins. The permit covers an area of 2,316km² in shallow water, 25km from the shore.
Located in OML 67, offshore Nigeria.
The Block MLHP-7 lies within the Rio Del Rey Basin comprises the IM, IE and IF wells, which will be developed as part of Etinde Development Stage 1. The partners submitted the draft for the EEAA in 2012.
Results from the drilling of the IM-5 well, completed in April 2013, were integrated into the EEAA in July 2013 and the final EEAA was submitted in January 2014.
Initial production from the project is expected in the first half of 2017. The fields within block MLHP-5 (Sapele) are expected to be developed under Stage II, and integrated to the facilities installed under Stage I.
Geology and drilling activities at Etinde
Oil and gas condensate within the block are located in the Miocene-aged Isongo sandstone formation. Bowleven completed the drilling of nine wells at Etinde starting from 2007.
The latest well to be drilled was the IM-5 well (Block MHLP-7) in April 2013, which will be the first to start production from the field. Wells were drilled using Noble’s Tommy Craighead and Sedco Forex International’s Trident IV jack-up drilling rigs.
Etinde Stage 1 development details
Taking the hub and spoke approach, the development concept for Stage I primarily involves the installation of unmanned platforms (the spokes), which will be connected to an onshore processing facility (the hub). The design will enable early production of liquids and also allow more platforms to be added as further discoveries are made.
Oil, condensate and wet gas will be delivered to the onshore facility, which will carry out liquids stripping and extract natural gas liquids (NGL). Up to 70 million cubic feet per day (mmscfd) of dry gas from the project will be supplied to Ferrostaal’s fertiliser plant for a period of 20 years.
Liquids and NGLs will be exported, with additional gas volumes expected to be supplied to SNH and GDF Suez.
Bowleven signed a strategic alliance agreement with Petrofac in November 2012, under which the latter agreed to provide $500m for the development of the project and $60m to cover the cost for drilling of the IM-5 well, project management, engineering, design, procurement and construction services.
In 2009, an independent competent person’s report (CPR) for the IF field in Block MHLP-7 was completed by TRACS International Consultancy, to assess the resource potential from the discovery.
