Lyginia-1, which is located about 13km southeast of the Dongara township, will primarily target the highest point on an anticlinal structure in the Dongara Sandstone, the main oil-producing reservoir in the Jingemia, Hovea and Eremia oil fields.

The well will be drilled directionally and is estimated to intersect the top of the Dongara Sandstone at a depth of about 2215m, about 146m southwest of the surface location.

Drilling and completion is expected to take about 17 days.

Eremia-6

Meanwhile, the partners said that following completion, the Eremia-6 well flow-tested at an initial rate of 3790 barrels of oil per day from the top of the Dongara Sandstone.

The well will now be put on production through the temporary flow-line until the permanent one is installed in about three weeks.

"This is another outstanding result for the Arc team and makes a hat trick for the three appraisal and development wells drilled in the program," managing director Eric Streitberg said.

"The well produced at somewhat higher rates than expected and has been placed on production less than three days after being handed over to the production crew."

Arc Energy, as operator, and Origin are equal partners in the well and the L1 licence.
