PHR's maiden production test at Siak well yields 1,274 barrels per day
Pekanbaru (ANTARA) - The first production test of the Libo SE #86 well in Siak Regency, Riau Province, by PT Pertamina Hulu Rokan (PHR) yielded up to 1,274 barrels of oil per day (BOPD) in early 2026.
Rokan Zone General Manager Andre Wijanarko said the achievement was exceptional as the production results showed a 0 per cent water cut, meaning the hydrocarbons extracted from the earth were pure oil with no water contamination.
"This achievement is tangible proof that with technological innovation and the hard work of PHR personnel, the Rokan Block still holds significant potential to support Indonesia's national energy security," he said in a statement received in Pekanbaru on Monday.
He said PHR applied a precise and innovative technical strategy to maximise potential in the Top Menggala layer at a depth of 5,680 feet with a maximum permeability of 2.2 Darcy.
Among the key technical factors behind the success was selective perforation, a method of selectively perforating the well casing to ensure oil flows from the most productive depth points of the reservoir.
This was followed by ESP pump optimisation, involving the use of a low-rate electric submersible pump tailored to the well's optimal production rate characteristics.
Additionally, advanced equipment was installed comprising a combination of an Advanced Gas Handler (AGH) on the subsurface pump and a Gas Separator at the surface facility to ensure stable oil flow despite gassy conditions.
"This success is an excellent start. PHR is committed to continuing to increase national oil and gas production by carrying out sustained drilling in the same area. Currently, the field team is moving swiftly to drill the Libo SE #88 well at the same wellpad," he said.
According to him, there are still four additional wells to be drilled (infill drilling) as a follow-up to the successful drilling of Libo SE #86, with the aim of maximising oil potential in the Libo SE area.
"We hope that going forward, PHR can continue to demonstrate operational reliability whilst maintaining HSE standards for energy security," he said.
