Perenco has been operating in the Republic of Congo since 2001, when Congorep, 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 steadily rising both through external growth and internal development, allowing for production to increase from 4,000 bopd in 2001 to peak above 50,000 bopd during 2014.
On the Emeraude Field, Congorep’s dedication in ensuring that all wells are effectively producing all of the time has enabled the production to jump from 4,000 bopd in 2001 to 12,000 early 2016. To maintain this plateau, various technological innovations were used, including state of the art methods of activation, a steam injection pilot comprising a new self-elevating platform, four steam injection wells and nine production wells. In 2014, a strong focus was given to the northern area reactivation with the final commissioning of a de-watering system, able to process up to 80,000 barrels per day and the full reactivation of three platforms. The 10% annual natural decline of the Emeraude Field is therefore widely compensated by these and other actions such as water shut off, pump upsizes and stimulation.
In the north offshore Congo, on the Yombo Field, Perenco has been operating the Conkouati FPSO and the two Yombo platforms on behalf of the Marine I Association since 2002. Thanks to constant efforts focused on water injection, stimulation and well optimisation over the past two years the production is close to 10,000 bopd.
In July 2010, Congorep took over operations on the Likouala Field. In addition to the operational synergies created with Emeraude, a heavy acquisition and study program was launched leading to the unveiling of the potential in the Upper Cenomanian. In 2012, a heavy work-over campaign targeting additional perforation in the Upper Cenomanian reservoir raised the field production to over 12,000 bopd. In 2014, the success of the drilling campaign with five new appraisal / delineation wells raised the Upper Cenomanian STOOIP by more than 100 Mstbo. Simultaneously, many surface works were completed, in order to cope with the increased production from 5,500 in 2010 to a record 32,000 bopd in 2014, higher than the peak production almost 30 years ago. The water injection capacity was also raised from 10 000 barrels per day to 50,000 barrels per day in order to maximize reserves for the long term. The Likouala Field currently produces 21,000 bopd.
