Sidayu-4V’s rework is part of the plan of development (POD) for the Sidayu field, which is located in the Pangkah production sharing contract (PSC), as approved by SKK Migas in October 2017.
Once Sidayu-4V has been reworked the field’s POD calls for re-entry operations at SID-3ST and drilling the SD-1 well. Initial production from the three wells is expected to reach around 7,000 bpd of oil and 3.9 mmcf (110.45 cubic metres) per day of gas.
Widiantoro also said new production was expected to come from the country’s largest oilfield.
Small gains
The official noted that well maintenance activ- ities at the B01 and C02 wells had succeeded in increasing crude production from Banyu Urip by 8,000 bpd.
Widiantoro said B01’s gas shutoff treatment saw production climb from 7,000 bpd per day to 10,000 bpd, while associated gas output had plunged from 17 mmcf (481,400 cubic metres) per day to 4 mmcf (113,300 cubic metres) per day. Acidising at C02, meanwhile, lifted pro- duction from 4,500 bpd and 1.5 mmcf (42,500 cubic metres) per day to 9,500 bpd and 3.5 mmcf (99,100 cubic metres) per day.
The Banyu Urip field lies in the Cepu block, which US super-major ExxonMobil operates with a 45% interest. State-owned Pertamina owns 45%, while the remaining 10% is split between four local government companies – Sarana Patra Hulu Cepu, Asri Dharma Sejahtera, Blora Patragas Hulu and Petrogas Jatim Utama Cendana.
Widiantoro said Banyu Urip was experienc- ing a natural production decline, indicated by
rising water ratio, gas ratio and scale in several production wells.
“Banyu Urip’s peak production has lasted for five years, or three years longer than the initial POD estimate. In addition, the peak oil produc- tion level is also around 30% higher than the ini- tial planned POD production level,” Widiantoro said.
SKK Migas revealed in June that production from the country’s largest oilfield had entered decline. The regulator’s head, Dwi Soetjipto, told a press conference on June 9 that the field had reached a production plateau of more than 220,000 barrels per day over the last five years, far exceeding the development team’s original estimate of 165,000 bpd.
What next
SKK Migas is choosing to celebrate its wins, no matter how small they are, while also being real- istic about the country’s near-term production targets.
The projects mentioned above underscore Indonesia’s biggest problem at the moment – the lack of what Wiratno referred to as a “significant increase in oil discoveries”. These smaller addi- tions help, but Indonesia needs major new pro- jects in the pipeline if is not only to turn around production declines but lift output to 1mn bpd by 2030.
Given the time it takes to bring new upstream on line, even before COVID-19 slowed the pro- cess furth0er, and SKK Migas’ caution over near-term production targets is understanda- ble. However, time is marching on relentlessly and unless something changes soon the country will be forced to admit that its 2030 target is also unobtainable.™
