Australia's Cue Energy Resources Limited reported Wednesday that the Naga Selatan-2 well (NS-2) in the Mahakam Hilir Production Sharing Contract (PSC) in Indonesia has discovered oil and is currently being suspended to allow for future production testing. The well has safely reached total depth (TD) at a depth of 1,170 feet.
NS-2, the first well to be drilled by Cue as Operator, is located onshore within the Mahakam Hilir PSC (Cue 100 percent and Operator) in the Kutai Basin, East Kalimantan, Indonesia.
The well was designed to test a shallow anticlinal closure with potential hydrocarbons very near the surface. The model was validated early on by gas shows from 300-315 feet, but this
The lower section of the hole (720–1,170 feet) encountered oil shows and high background gas, however due to drilling constraints caused by high pressure, the decision was made to TD the well before the planned 2,240 feet. This section could not be logged and will be plugged, leaving the 9.625 inch cased hole for production testing. Engineering and geological studies integrating all of the data from the well will be undertaken to determine an optimal production testing program.
NS-2 has successfully validated a play concept analogous to the nearby Sanga Sanga fields and use of appropriate technologies will be used to further delineate the sweet spots along
