Canada – PekiskoIn Alberta, Canada, Canadian Abraxas has six horizontal Pekisko wells on production, although two of which have yet to be fracture stimulated. Due to the recent steep decline on oil prices, the decision was made to postpone significant additional capital expenditures until oil prices improve in the field. Also in Alberta, the Company previously announced the acquisition of over 20,000 net acres in an emerging oil shale play similar in character to the Eagle Ford oil window in South Texas. We are still in negotiations to acquire additional leasehold interests in the play and upon conclusion of these negotiations, we will be in a position to announce the location of this exciting new play. Recently three wells have been permitted in the play by other operators. Comments “The operations success during the second quarter along with the Eagle Ford and West Texas transactions announced yesterday, should place Abraxas into a position to continue substantive production growth on into the future using cash flow augmented by prudent use of availability under our existing bank line,” commented Bob Watson, Abraxas’ President and CEO.
