LONDON (Alliance News) - SOCO International PLC Tuesday said an exploration well on a block offshore Republic of Congo that it has been testing "significantly" exceeded pre-test expectatons, reaching a post stimulation frac peak rate of 5,174 barrels of oil per day and 3.65 million standard cubic feet of gas per day.
In a statement, the oil and gas explorer and producer said the Lidongo X Marine 101 ST1 well on the Marine XI block encountered oil in a clastics sequence in the Djeno sand formation with drilling shows and early log interpretation indicating approximately a 50 metre gross interval.
The 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.
The test, over a perforated 20 metre section, produced at a stable average flow rate of 4,800 barrels of oil per day and 3.5 million standard cubic feet of gas per day on a 56/64" fixed choke with a flowing wellhead pressure of 778 psi following the successful execution of the stimulation frac, SOCO said. The oil quality was 32 degrees API.
"The well results will now be analysed in order to determine the continuity of the well with the nearby discovery in the Marine XII Block," the company added.
SOCO EPC holds a 40.39% interest in the Marine XI Block. Project partners are WNR with 23%, SNPC with 15%, AOGC with 13.11% and PetroVietnam Exploration and Production with 8.5%.
