Premier Oil Begins Drilling Indonesia’s Tuna PSC Area

Premier Oil has started drilling the first of two offshore exploration wells in the Tuna production sharing contract (PSC) area in Natuna Sea, north of Indonesia.

The company is using the semi-submersible Ocean General rig for the drilling activities.

Both the Gajah Laut Utara-1 and Belut Laut-1 wells will target multiple-stacked Miocene and Oligocene reservoirs in fault-dependent closures, which are independent of each other.

The Gajah Laut Utara-1 well has a low-case, pre-drill potential of 40 million barrels of oil equivalent and a medium-case potential of 90 million barrels of oil equivalent on a gross basis.

The Belut Laut-1 well has a low-case pre-drill potential of 40 million barrels of oil equivalent and a medium-case potential of 90 million barrels of oil equivalent on a gross basis.

Premier Oil owns a 65% stake in the Tuna PSC, according to upstreamonline.com.
