JAKARTA, Nov. 13 (Xinhua) -- Indonesia's state-run oil and gas producer, Pertamina, has proposed its desire to have a 10 percent of 'Participating Interest' (PI) over the exploration and production of gas in two gas blocks located in East Kalimantan province that belong to U.S. oil and gas firm Chevron, a local media reported here on Friday.

    Regarding its intention to have the 10 percent cost sharing scheme to explore and produce gas in Chevron's Ganal and Rapak gas blocks, Pertamina has filed in its proposal to the oil and gas director general office at the Energy and natural Resources ministry, a senior Pertamina official said.

    "We also had discussed this issue with our Chevron counterpart," Pertamina Stream Planning and Evaluation Deputy Director Gunung Suhardjono was quoted by the Detik.com as saying.

    Gunung said that the sum of fund required in the joint operation was yet to be determined during the talks with Chevron. "But we have allocated the fund required for the joint operation," Gunung added.

    Ganal gas block has two gas fields that consisted of Gehem and Gendalo. Meanwhile, the Rapak gas block has one gas field namely Rangas. The two gas deposits are located in the deep sea of East Kalimantan province's waters.

    Chevron controls 80 percent shares in the two gas blocks whose exploration is expected to commence in 2013.

    Earlier reports said that the PI talks between Pertamina and Chevron has been underway since 2007.
