The Rokan zone alone drills nearly 500 wells annually, the highest tally of any single operating area in Indonesia.

Production from Indonesia's most vital oil block in Riau could drop by nearly a third within a single year without an aggressive drilling campaign, a senior executive at PT Pertamina Hulu Rokan (PHR) has cautioned, revealing the stark depletion rates forcing the company into a relentless race to maintain baseline output."The baseline when we talk about production, at PHR, it was almost 200,000 [barrels of oil per day]. If we don't do anything, that's it; it's a decline," Muhammad Arifin, director of PHR Regional 1 Sumatra, said in Bogor, West Java, on Wednesday.
"If we produce 200,000 [bpd] a year and just open and close the valve, the next year it's gone by 30 percent. Our production is down to around 140,000. The following year, another 40 percent is gone."
The Rokan zone alone drills nearly 500 wells annually, the highest tally of any single operating area in Indonesia. Zone 4 in South Sumatra drills almost 100 wells, while Zone 1, stretching from North Sumatra to Jambi, adds another 40 to 50.
