LONDON -- The HVJOC joint venture has received approvals from the Vietnamese government of an updated full- field development Plan for the Ca Ngu Vang (CNV) project.

The CNV field is in block 9-2 in the Nam Con Son basin offshore southern Vietnam.

According to partner SOCO International, the new program includes drilling of theCNV-7P development well, which will access the previously undrilled southwestern corner of the field.

Drilling should start in 2Q 2014, with the well coming onstream as a produce in 3Q.

In block 16-1, the HLJOC joint venture spudded the TGT-10X exploration/appraisal well in mid-June on H5, the main undrilled fault block in the Te Giac Trang field. The location is 6 km (3.7 mi) south of the H4 wellhead platform.

During drilling into the Oligocene D2 section, the well encountered higher formation pressure than predicted, SOCO said. Due to difficulties running a liner over the Miocene and Oligocene reservoir horizons, the partners agreed to re-drill the reservoir section in which the liner was to be run.

Although this extended the program, the fresh hole section reduced the risk of issues arising during the testing phase, SOCO added. Testing is under way and will comprise three separate tests: one on the Oligocene, in two parts, with twofurther tests on the Miocene.

To date, the first test over a 190-m (623-ft) section in the Oligocene C has flowed 41.1° API oil and gas.
