Pertamina drilling two wildcats ? E. Java and S. Sumatra

State oil company Pertamina is drilling wildcat wells in East Java and South Sumatra, both onshore and both on its own operated blocks, OGI News reported.

OGI News quoted Pertamina as saying that each of the new wells are to test untested areas that are thought to be prospective.

Pertamina spudded the first of the two, its Kemangi-1 exploratory well on the EPIII Block in East Java at the end of July. The wildcat's drillsite is approximately 25 km west of a gas discovery well drilled at the end of 2000, the Suci-1. That well tested 8.6 million cubic feet per day of gas, which Pertamina hopes will be duplicated with this new probe of the Lower Ngimbang formation, which is targeted at a total depth for the well at 4,478 feet (1,365 meters).

The second wildcat is farther a field, in the Jambu Timur region of South Sumatra. The exploratory well Gemilang-1 was spudded on August 4th in Block UEP II targeting the Air Benakat formation at a total well depth of 6,152 feet (1,875 meters), to tap into the Ketaling Timur Field structure should it extend this far.
