JAKARTA. Pertamina EP has succeeded finding oil and gas from exploration of Tiung Biru structure for 2.546 barrel oil per day (BOPD) and 2, 75 million standard cubic feet of gas per day (MMSCFD). The success is the first exploration finding in Indonesia in early year 2012.

The finding of oil and gas has been proven through drill stem test (UKL)-1B in Tiung Biru well (TBS)-2STT with interval 2174 – 2179 m and 2169 – 2172 in Kunjung Formation in 48/64 inch tongs. The test is one of six UKL approved by BPMIGAS.

The President Director of Pertamina EP, Syamsu Alam stated hat through this success is hoped to be able to reach the target of finding oil and gas in Indonesia. “We thank God that a quite abundance oil and gas succeeded to be found in Tiung Biru. Hopefully the finding could increase optimism of oil and gas exploration in Indonesia,” he says. 

Tiung Biru structure is located about 15 km of southeast of Cepu, Central Java or about 28 km of southwest of Bojonegoro, East Java. The Project of Exploration Focus Area (PAFE) Tiung Biru managed the structure of Tiung Biru which structurally is a whole structure with Jambaran structure managed by Mobil Cepu Ltd.

To encourage the increase of Pertamina EP’s oil production, Pertamina EP hastens the development of Tiung Biru structure through POP program (Put on Production) from TBR-1ST well with its production target is 210 BOD, which will be reached by Q2/2012. Pertamina EP also proposed TBR-2ST well to be able to produce with the same production scheme through POP with its production target 1000 BOPD.

The drilling result of TBR-1ST exploration well did in 2009 is received oil, condensate, and gas. Next, to evaluate the existence of hydro carbon in Tiung Biru structure, BPMIGAS has agreed the drilling of two appraisal wells; TBR-2ST and TBR-3. The drilling of Tiung Biru-2ST well, which is deviated well, was drilled in the north part of Tiung Biru structure on October 7th, 2011 up to the final depth 2206 mMD and found oil and gas.

The exploration of PAFE Tiung Biru is meant to poof the existence of hydro carbon in Tiung Biru structure, which will be the base in unitization process of Tiung Biru-Jambaran between PT Pertamina EP and Mobil Cepu Ltd. Based on drill stem test in Kujung Formation; there are also significant oil reserves besides gas.  (AK)
