Perenco Congo (Perenco) announces the completion of its successful drilling campaign on the Tchibouela East field, offshore Republic of Congo. The results of the five infill well campaign, which concluded at the end of 2025, now show a sustained material uplift in production, providing an additional 6,000 barrels of oil per day (bopd).

The drilling campaign entailed advanced offshore drilling techniques, including horizontal and ushaped wells, which resulted in higher oil recovery, while reducing operaIonal risks.

Following the posiIve results from the Tchibouela East campaign, Perenco Congo has now started a new five well drilling campaign on the Masseko field, designed to increase producIon from the field as well as tesIng a new geological horizon.

Commenting on the announcement, Gregoire de Courcelles, Managing Director of Perenco Congo said:
“We have seen a sustained uplift in production following the recent five well infill campaign on the Tchibouela East field. This positive result clearly demonstrates our ability to extend field life and maximise the value of acreage for the benefit of all stakeholders. Tchibouela East has been in production for almost thirty years and we are pleased to help ensure that the field can produce for many more years to come. The operational tempo continues and we are now drilling on the Masseko field, where initial results from first production are encouraging.”
