PT Perusahaan Gas Negara (Persero) Tbk (PGAS), through its subsidiary PT Saka Energi Indonesia (SEI) once again found oil and gas reserves in an exploration well Sidayu-4V, Pangkah Block, offshore East Java. This exploration activity has been carried out to to follow the discovery of oil and gas in the exploration well Sidayu-3ST1 last year, and proved that the extention of oil and gas baring reservoir (Tuban, Kujung-1 and Ngimbang) in Sidayu structure. The potential oil and gas resources of the Tuban, Kujung-1 and Ngimbang layers along the JS-1 (JS-1 Ridge) is estimated in the range of 300 million BOE.

Currently, the production of the Pangkah block comes from Ujungpangkah field. Sidayu will be the second field that will also utilize the same production facilities as what Ujungpangkah field has. This successfull discovery encourages Saka to continue its exploration activities to realize the potential of oil and gas resources that have been identified in several prospects with drilling work in the north and west of Pangkah Block in 2017-2018.
