Vietnam TGT partners to drill offshore on southern fault block

Offshore staff

LONDON – SOCO International says the Te Giac Trang (TGT) field offshore southern Vietnam continues to perform as expected, currently delivering 52-55,000 b/d of oil.

Production comes from two 16-slot platforms with 16 producer wells. The second platform entered service in July 2012.

The partners plan further drilling and appraisal as part of the ongoing development, with three to four infill wells planned this year, along with the H5 step-out appraisal well. The program is expected to start this spring.

TGT extends over 13 km (8 mi) and at least five fault blocks. Its producing reservoir comprises a complex series of more than 50 clastic Miocene and Oligocene reservoir intervals.

RPS Energy Consultants estimate oil in place in the 466-958 MMbbl range, with potentially 53-152 MMbbl still to be discovered, particularly in the undrilled southernmost fault block, H5.

Based on data from producing wells and the provision of injection support, RPS estimates recovery potential at 28-35%. However, SOCO believes that further drilling and longer-term production will continue to de-risk the field and boost recovery to 45-50%.
