According to reports, Pertamina EP, the oil exploration subsidiary of Pertamina, has allocated $100 million to invest in the enhanced oil recovery programme to extract the maximum quantity of oil from its old wells. This programme involves using a highly expensive process to optimise crude oil production at an old oilfield. The process involves the injection of water or chemicals before drilling deeper into the well. Pertamina is looking to extract an additional 30,000 bpd from its old oil wells. The company will conduct the programme at its fields in Rantau, Kenali Asam, and Tempino, including the Tiga Barat and Tanjung areas.
