A dispute has arisen between the operator Pioneer Natural Resources, and its partners in Block H offshore Equatorial Guinea, including Roc Oil, Atlas Petroleum and PA Resources' subsidiary Osbourne Resources. The essence of the dispute is a disagreement about how and when a second exploration well should be drilled in Block H and the costs for this. Arbitration has been claimed and the drilling of the well is postponed. PA Resources has a 3.1 percent participating interest in the block. PA Resources AB (publ) today announces that a dispute has arisen between the operator Pioneer Natural Resources Equatorial Guinea Limited (“Pioneer”), and its partners in Block H offshore Equatorial Guinea, including Roc Oil Equatorial Guinea Company (“ROC EG”), Atlas Petroleum International Ltd (“Atlas”) and PA Resources AB, through its wholly-owned subsidiary Osbourne Resources Ltd (“PA Resources”). The essence of the dispute relates to the Farm-in Agreements, which each partner in Block H entered into with Pioneer in 2004. These agreements implied, in brief, that Pioneer gained participating interest in the Production Sharing Contract for Block H, and in exchange, Pioneer committed to pay a share of the future costs of drilling two exploration wells in Block H. The two wells are part of the working obligations for Block H which the state of Equatorial Guinea has approved. The first of the two wells, H-1 (Bravo), was drilled in June 2004. Pioneer thereby discharged its responsibility in that regard. However, ROC EG, Atlas and PA Resources maintain that Pioneer has breached its obligations with regard to the second well. In August 2005, all the partners in the Block H, including Pioneer, resolved to drill the H-2 (Aleta) well in satisfaction of the work obligations for Block H. That well would also have discharged Pioneer's obligations to the other partners under the Farm-in Agreements. The Government of the Republic of Equatorial Guinea subsequently approved the drilling of the H-2 (Aleta) well. Until early this year, all partners in Block H were proceeding on the basis that the well would be drilled, although the precise timing of the drilling was subject to rig availability. Earlier this year, Pioneer indicated that it did not wish to proceed with the drilling of the H-2 (Aleta) well and did not consider itself bound to fund its parts of the costs of drilling the well. Pioneer further indicated to the partners that there were two reasons for this: the enactment of a new Hydrocarbons Law by the Republic of Equatorial Guinea and escalating costs of drilling the well. PA Resources', as well as the other partners view, is that Pioneer is not entitled to take the position it has. In order to seek clarification of certain procedural matters under the terms of the Joint Venture Agreement which governs the operations and the co-operation between the companies, Pioneer commenced arbitration actions against ROC EG, Atlas and PA Resources, on 14 June 2007. Subsequently, ROC EG notified Pioneer of claims for breach of Pioneer's contractual obligations under the Farm-in Agreement between ROC EG and Pioneer and further advised Pioneer of its intention to pursue its claims through arbitration. PA Resources has authorized ROC EG to pursue the dispute. Until this dispute is resolved, it is unlikely that the drilling of the well H-1 (Aleta) will proceed. Pioneer Natural Resources Equatorial Guinea Limited, a wholly-owned subsidiary of Dallas-based Pioneer Natural Resources Limited, has a 50 percent participating interest in Block H. Roc Oil Equatorial Guinea Company has a 18.8 percent participating interest, Atlas Petroleum International Ltd a 28.1 percent participating interest and PA Resources AB has, through its wholly-owned subsidiary Osbourne Resources Ltd, a 3.1 percent participating interest.
