KrisEnergy abandons Mustika well in East Java Sea

  • Exploration & Production

KrisEnergy, an independent upstream oil and gas company, has completed drilling of the Mustika-1 exploration well in the Sakti production sharing contract (PSC) in the East Java Sea. The well will be plugged and abandoned as it is a non-commercial discovery.

Mustika-1 was spud a week ago with the KS Java Star drilling rig.

The well was drilled to a total measured depth of 2,768 feet (844 metres), or 2,667 feet total vertical depth subsea, and encountered gas in the Tuban and Kujung I formations.

According to KrisEnergy, 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, said the company.

Chris Gibson-Robinson, Director Exploration & Production, commented: “This is our final exploration well for 2015 with the first five being drilled in the Gulf of Thailand, all of which were successful. 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 4,974 sq. km in the East Java Sea over the western margin of the East Java Basin, Bawean Arch and the Muriah Trough.
