Since acquiring the Emeraude field in 2001, this asset has more than doubled its production. A steam injection pilot comprising one new platform, four steam injection wells, and nine production wells was launched in 2009. Steam injection began in April 2010. In order to monitor the steam flood process, Perenco is deploying a number of methods, including the acquisition of regular 3D seismic surveys to monitor steam chamber evolution.
In July 2010, Congorep, the joint venture between Perenco and the SNPC took over the operation of the Likouala Field, which is located 25 km from the Emeraude Field. In addition to the operational synergies created, production was enhanced by work on existing wells following studies on the upper cenomanian reservoir. Production increased from 6 000 bopd in 2010 to 14 000 bopd in 2012.
In addition to the continuous work over programme on the existing well to maintain and enhance and production levels, two drilling campaigns are planned in 2013-2014 on Emeraude and Likouala.
On the offshore Yombo field, Perenco has been operating the Conkouati FPSO and the two Yombo platforms on behalf of the Marine I Association since 2002. A drilling campaign took place on the field in 2010 and 2011. The production level is currently approximately 9 000 bopd.
Perenco acquired the Marine IV exploration permit in December 2004. All commitments for the first period of the license were completed in 2008. Two 3D surveys were acquired during 2010 and 2011, and interpretation works are ongoing with our partners SNPC and Svenska. Additionally, a well was drilled on the Mukulungu prospect at the end of 2012.
