Dejour Energy has said that it will drill an initial vertical well in May 2011 to test the Mancos/Niobrara potential on its 7,000-acre leasehold in Colorado, US.

The company said that the targeted zones are known to contain both oil and natural gas in this area.

The private operators R W Bayless and Foundation Energy are currently exploiting the lower Mancos zone, approximately six miles to the southwest of Dejour’s proposed well location.

Pending a successful outcome of the test well in proving the extension of the play to Dejour’s leasehold, Dejour, project operator and 72% working interest holder, plans to commence a formal horizontal well development program.

According to the company, a secondary target in the upper Mancos known as the Castlegate Sand will also be evaluated within this initial test well.
