Tanjung Field Oil Production Targets Up Significantly

Application of Enhanced Oil Recovery (EOR) in Tanjung field by Pertamina EP is expected to increase production up to four times.
“After the pilot EOR project in Tanjung Field has been completed which is around 12 months, later launched a new project as a whole, is expected in the next few years oil production can be increased three to four times,” said Deputy Minister of Energy and Mineral Resources, Susilo Siswoutomo hope, Monday (07/29/2013).
To support the EOR program, Pertamina EP will make 48 to 50 injection wells and production wells 134. “We expect production to reach 18,000 barrels per day in 2016,” said Vice Minister.
Susilo added that this applied EOR process will not interfere with the environment because that is injected is not a hazardous material. “The adverse effects on the environment, does not exist because it is injected salt, soda and surfactants made IPB. The whole must meet environmental criteria, so no one will be channeled into the trenches, “said Susilo.
Regarding the success rate of the EOR project, Susilo said, depending on the indication shown from the results of wells that have been injected, the current has been injected for eight months. The result, based on three monitoring wells of 300 meters which dinjekskan showed an increase in production.
EOR technology is one of the advanced oil depletion method for optimizing the production of an oil and gas field. EOR is a key national oil production, but the high cost is an obstacle in the application of EOR application.
Tanjung Field EOR project contract was signed in 1989 followed by a pilot project in 1990 and began full operation in 1995.
At the time of the injected fresh water into the well of 100,000 barrels of water per day, and produce oil in the range of 10,000 barrels of oil per day. Currently EOR with chemical injection was implemented Pertamina EP’s especially Tanjung Field by injecting in one of the wells as a pilot project.
