Australia-listed Cooper Energy has managed to restore production at the Tangai-3 workover well in Indonesia.
The well, located at the Sukananti project, had been shut-in since 1997 when the field was held by another operator.
Cooper carried out a workover on the well which then produced at a rate of between 77 and 126 barrels of oil per day, with an 80% to 85% water cut, over a five=day period.
Well testing is set to continue before the well is connected to a 500-metre flowline to the existing infrastructure at Tangai-1, with output to be shipped via trucks in the interim.
Cooper said it had plans to add an artificial lift to the well, which could potentially increase production from the Tangai-3 to about 100 to 200 bpd.
Previously the company restarted production from Bunian-1 and Tangai-1 on the same block.
Managing director David Maxwell said he was pleased with how the restart programme was tracking and the levels of production being achieved.
“Through a relatively low risk, capital-light approach we have been able to lift production to 380 bpd through a process of analysis, gaining a fresh understanding of the fields and the application of basic operations and technology,” he said.
“We have identified further opportunities, which we are planning to address in the current financial year.”
The company had some positive news from its Indonesian projects which combined produced 55,000 barrels of oil in the 12 months to the end of June. This is more than double the previous corresponding number of 25,000 barrels.
This is set to grow as the company continues its restart programme with the Bunian-3 and Tangai-5 wells, with potential for another well after that depending on the outcome of the previous two.
Cooper is the operator of the licence, with a 55% interest. The rest of the interest is owned by Foster Oil & Energy.
