Perenco has been operating in the Republic of Congo since 2001, when a joint venture with the SNPC was created in order to operate the Emeraude field. Since then, the partnership has grown stronger and production has been raised both through external growth and internal development, allowing for production of 40 000 bopd at the end of 2013.

In July 2010, Congorep, the joint venture between Perenco and the SNPC took over the operations on the Likouala Field.  In addition to the operational synergies created with Emeraude, the historical Congorep operated field, a heavy acquisition and study program was launched leading to the unveiling of the potential in the upper cenomanian reservoir.

2012 saw the start of a heavy work-over campaign targeting areas where wells were present and 2013 saw the conduct of a drilling campaign to access further parts of the field.

On the Emeraude field, Congorep's dedication to ensuring all wells are effectively producing all of the time has enabled the production to jump from the 4 000 bopd in 2001 to a steady range of 8 000 to 10 000 since 2006.  To maintain and increase this plateau various technological innovations were used including, innovative activation, steam injection as a pilot comprising one platform, four steam injection wells, and nine production wells, and in 2014 highly deviated wells.  The natural decline of the Emeraude field (10% a year), is therefore widely compensated by these and other actions such as  water shut off, pump up size and stimulation.

On the North 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 over 2010 and 2011 with a considerable focus  on water injection. In 2013, the production level remains around 9000 bopd on Yombo.
