KrisEnergy, an independent upstream oil and gas company, announces that it has completed drilling of the Mustika-1 exploration well in the Sakti production sharing contract (PSC) in the East Java Sea.

Mustika-1 was drilled to a total measured depth of 2768ft (844m), or 2667ft total vertical depth subsea, and encountered gas in the Tuban and Kujung I formations. Initial indications from wireline logs are that the gases have a high carbon dioxide content and therefore are likely to be below the economic threshold for a commercial discovery. The well will be plugged and abandoned and a detailed analysis of the well data and gas samples will be undertaken to review the remaining prospects and leads in the Sakti PSC.
“This is our final exploration well for 2015 with the first five being drilled in the Gulf of Thailand, all of which were successful,” said Chris Gibson-Robinson, director exploration and production. “The first four wells resulted in the recently approved plan of development for the Rossukon field."
KrisEnergy was awarded the Sakti PSC in February 2014. The block covers 4974sq km in the East Java Sea over the western margin of the East Java Basin, Bawean Arch and the Muriah Trough. KrisEnergy is also the operator of the Bulu PSC, which is adjacent to the Sakti PSC and contains the Lengo gas discovery for which the company received approval for its plan of development in December 2014. Front-end engineering design for the Lengo development was completed in the third quarter of 2015. Gas sales negotiations are ongoing and preparations are underway to tender the contract for engineering, procurement, construction and installation.
