Origin Energy says that the Jingemia-4 appraisal well located in the onshore Perth Basin Exploration Permit 413 in Australia, was spud this week using the Century 11 drilling rig.

The Jingemia-4 well is being drilled from a surface location approximately 350m east-northeast of the Jingemia production facility and has been located to intersect the Dongara Sandstone oil reservoir near the crest of the field. The aim of the well is to provide a second oil production well at the Dongara Sandstone oil reservoir level and to appraise the reservoir potential of the immediately underlying Wagina Formation, which is interpreted to be above the oil water contact at the Jingemia 4 location. Drilling to the top of the reservoir zone is expected to take 10 to 14 days.

Coring of the Dongara Sandstone and Wagina Formation reservoirs is planned to provide information which will enable the field development plan to be optimized.

Granting of a production license for the Jingemia field is imminent.

Commenting on the well Norwest's Director, Andrew Svalbe said, "Jingemia-4 is an important well for Norwest. We anticipate that a successful well will support up to a doubling in oil production rates from the field (Jingemia-1 is currently producing at about 2,000 bopd) and we are hopeful that an upgrade in field reserves will also result in due course.
