LONDON – Production from the Te Giac Trang (TGT) field in the Nam Con Son basin offshore southern Vietnam is in the range of 50-56,000 b/d, according to partner SOCO International.
Five wells are onstream at the H4-WHP TGT southern platform, which entered service in July. The field’s daily rate fluctuations reflect well intervention activities.
A one-day “high rate” flow test was conducted on the TGT FPSO at 60,789 b/d, SOCO adds. No issues were evident in either reservoir performance or FPSO operability.
Data gathered during this test is being analyzed to enable the partners to identify and alleviate bottlenecks in the systems, in order to establish the FPSO’s oil production handling potential.
At TGT’s northern platform, H1-WHP, the PetroVietnam jackup PVD-II has been working on a four-well, infield development drilling program that included two infill wells, an appraisal well, and one development well.
The TGT-15P and TGT-16P infill wells on the H1.1 fault block and the TGT-8X appraisal well on the H2N fault block were batch drilled into the reservoir section. All are now onstream.
However, the TGT-17P development well was suspended following a “twist-off” in the bottomhole assembly above the reservoir section. The rig has since departed ahead of the monsoon season, but will return to the TGT field next spring for the 2013 drilling campaign, which will include completing the TGT-17P well.
Offshore the Republic of Congo (Brazzaville), SOCO is a partner in the Marine XI offshore concession.
The consortium has agreed to drill the Lideka Marine East 1 well before the end of the year, following analysis of previously acquired data on the block, including results of the Lideka Marine 1 well drilled by the previous concession holder.
The new well will test both the structural closure updip from an oil leg encountered in the Sendji Formation in Lideka Marine 1 (2 km/1.2 mi to the west), and a large structural closure in the overlying Tchala formation.
