UK-listed Pharos Energy has officially started a six-well drilling campaign at its offshore Vietnamese assets in Blocks 16-1 and 9-2, with total capital expenditure of approximately US$ 36 million and plans to complete by mid-2026.

Operations began on 18 October with the first infill well on the H1 fault block of the Te Giac Trang (TGT) field, located in Block 16-1. The campaign comprises four wells at TGT (three infill wells and one appraisal well) and two wells at the Ca Ngu Vang (CNV) field in Block 9-2 (one infill, one appraisal).

Pharos has contracted two jack-up rigs from Borr Drilling: the GunnLod will carry out the TGT campaign, while the Thor will operate at CNV. At TGT, the first H1 infill well is scheduled to take around 28 days; the rig will then move to H5, followed by an appraisal well (TGT-18X) expected in early December with an estimated duration of about 40 days. The final TGT infill well, TGT-H4, will complete the slate with drilling expected to finish in the first half of 2026.

For CNV, the Thor rig is mobilising in early November, with drilling of the CNV-8P infill well expected to commence mid-November and take roughly 90 days. The subsequent CNV-5X appraisal well, targeting the northern section of the field, is planned to start in mid-February and continue for about 108 days.

Pharos states that all six wells can be tied into existing infrastructure immediately upon completion, enabling any successful wells to bring incremental production on-stream quickly. CEO Katherine Roe commented: “We are delighted to begin our six-well infill and appraisal drilling programme in Vietnam. This important and material campaign is designed to drive significant production growth from 2026 onwards.”
