SOCO International has completed testing the Lidongo X Marine 101 ST1 exploration well, offshore Democratic Republic of the Congo.
The Lidongo X Marine (LXM) 101 well, in the Marine XI block, is situated 23km north-west of Pointe Noire in a water depth of about 45m.
The well, which was drilled to a total depth of 2,665m, reached 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).
SOCO said the well encountered oil in a clastics sequence in the Djeno sand formation, with drilling and early log interpretations suggesting a 50m gross interval.
The test produced a stable average flow rate of 4,800 bopd and 3.5 MMSCFD on a 56/64in fixed choke with a flowing wellhead pressure of 778 psi after the execution of the stimulation frac.
