Lidongo X Marine 101 well offshore Congo exceeds pre-test expectations

SOCO has announced that the its subsidiary has successfully completed testing the exploration well Lidongo X Marine 101 ST1 well reaching a post stimulation frac peak rate of 5,174 barrels of oil per day (BOPD) and 3.65 million standard cubic feet of gas per day (MMSCFD).

According to the operator SOCO EPC operator of the Marine XI Block offshore the results significantly exceeded pre-test expectations.

The test, over a perforated 20 metre section, produced at a stable average flow rate of 4,800 BOPD and 3.5 MMSCFD on a 56/64″ fixed choke with a flowing wellhead pressure of 778 psi following the successful execution of the stimulation frac. The oil quality was 32 degrees API.

Soco now says the well results will be analysed in order to determine the continuity of the well with the nearby discovery in the Marine XII Block.

The LXM-101 well, located 23 kilometres northwest of Pointe Noire in a water depth of approximately 45 metres, was drilled to a total depth of 2,665 metres encountering oil in a clastics sequence in the Djeno sand formation with drilling shows and early log interpretation indicating approximately a 50 metre gross interval.

SOCO EPC holds a 40.39% interest in the Marine XI Block while its partners WNR hold 23%, SNPC 15%, AOGC 13.11% and PetroVietnam Exploration and Production (PVEP) (8.5%).
