Tri-Valley Corp has completed an expanded phase one development drilling program at its Claflin oil project in the Edison oilfield near Bakersfield, California, US.

The company has drilled eight new wells, which are part of its overall plan to drill a total of 22 new wells at Claflin during 2011.

This program is in line with the company’s strategy to convert 2.1 million barrels of net proved undeveloped oil reserves (PUDs) on the property to proved developed and producing (PDP) status and to increase oil production.

Currently, it is completing the installation of well-site production equipment and tie-in of the new wells to existing production facilities at Claflin.

The company expects to commence an initial steam injection cycle on the first well in early May and that the new wells will have received an initial steam injection cycle by the end of July.

Following first production from these new wells, there will be a 90-day evaluation period during which the company will analyze the performance of the new wells prior to commencement of the second phase of the Claflin development to complete the remaining 14 new wells by the end of the year.
