SOCO Updates on Drilling Operations in Vietnam, Congo and Angola

SOCO International plc, an independent oil and gas exploration and production company, gave an update on the firm's operations in Vietnam, Congo and Angola.


SOCO announces that the drill stem tests thus far on the TGT-10XST1 well exploration well on the H5 fault block of the Te Giac Trang (TGT) field, have exceeded all pre-test expectations. Combined peak production from two of the three zones tested is over 16,500 barrels of oil per day (bopd). The third drill stem test in the well, which encountered approximately 820.21 feet (250 meters) of gross pay section (approximately 390.42 feet or 119 meters of net pay) in the Miocene and Oligocene reservoir horizons, is now underway.

The first test, over a net 305.11 feet (93 meter) section in the Oligocene “C”, produced at a maximum rate of 9,488 bopd and 1.16 million standard cubic feet of gas per day (MMscf/d) of 41.1 degree API oil. The second test, over the Miocene Lower 5.2L sequence, tested a net 155.18 feet (47.3 meters) interval. The maximum flow achieved over this interval was 7,100 bopd and 1.76 MMscf/d.

The final test is of the Lower Miocene Intra Lower Bach Ho 5.2 Upper and Lower sequence, testing an additional net 290.68 feet (88.6 meters). This test has just commenced and should be completed in another 5-7 days.

The well is located approximately six kilometres south of the H4 Well Head Platform, which is in the southern part of the TGT field in Block 16-1 located in the Cuu Long Basin off the southern coast of Vietnam.

The Lideka East Marine-1 well (LDKEM-1) targeted a post-salt structure, up-dip from the Lideka Marine-1 well which found shows of oil in the Sendji Formation (iS3). The well encountered approximately 164.04 feet (50 meters) of net pay section in the Upper and Lower Sendji, of which approximately 98.42 feet (30 meters) of net pay are within the targeted iS3 and S4 horizons.

The LDKEM-1 well was tested over a 65.61 feet (20 meter) interval in the iS3 and S4 horizons. The well flowed 30-35 degree API oil at a sustained rate of 350 bopd, with base, sediment and water around 1 percent, in line with predictions from the petrophysical analysis. Produced gas volumes were very low.
