Interra Ends Drilling at TMT-57 Well in Tanjung Miring Timur Oil Field

Interra Resources Limited (the Company or Interra) disclosed Wednesday that its wholly owned subsidiary, Goldwater TMT Pte. Ltd. (GTMT), has completed development well TMT-57 at the Tanjung Miring Timur (TMT) field in South Sumatra, Indonesia as an oil producer. GTMT has 100 percent operating interest in the Technical Assistance Contract of the TMT field and the cost of drilling was funded from existing funds on hand.

TMT-57 was drilled as an infill development well between current producing oil wells with the primary objective of accelerating production from undrained portions of oil reservoirs which produce in surrounding wells. TMT-57 was drilled to a depth of 3,832 feet (1,168 meters) and is the second of four development wells to be drilled back-to-back using an externally contracted rig. It is a continuation of drilling in-field wells to test new geologic and reservoir concepts derived from the 2012 3D seismic survey.

Following perforations covering three deep reservoirs, the well flowed naturally at relatively high rates. Unexpected pressures were encountered indicating potential new reservoirs. After four days of testing to determine optimum natural flow rates, while maintaining formation pressure and reducing possible water influx, TMT-57 was completed as a significant oil producer at a stable 650 barrels of oil per day.
