In the first transaction in the Gulf of Mexico since the oil spill in April and the subsequent drilling moratorium, Matt McCarroll’s Dynamic Offshore Resources LLC, Houston, has acquired properties on the Gulf shelf from privately held Samson Investment Co., Tulsa, Okla., for an undisclosed price.

The assets include 22,000 net acres in 16 federal and state blocks involving eight fields, the most prominent being a 100% interest in Vermillion Block 272 and a 50% interest in High Island Block 52. Current net production from the properties is approximately 4,500 BOE per day (60% oil). Dynamic will operate more than 67% of the acquired reserves.

The acquisition includes 32 active wells, 36 inactive wells, six platforms and two caissons in 30 to 175 feet of water.

The assets were marketed by BMO Capital Markets and included 27 federal and state blocks and 38,248 net acres (61% held by production; 74% operated). Total proved reserves in the divestment package were 6 million BOE (3.18 million barrels of oil; 16.8 million cu. ft. of gas), with 6.9 million bbl. equivalent proved, probable and possible. Net average cash flow for fourth-quarter 2009 was $7 million per month.

The divestment represented a complete exit of the region for Samson.

Dynamic Offshore was formed in January 2008 with a $450-million equity contribution from Riverstone Holdings LLC. In October, Dynamic acquired Gulf of Mexico-focused Beryl Oil and Gas LP, Houston.

Taqa North Ltd., a subsidiary of UAE-based Abu Dhabi National Energy Co. PJSC, or Taqa, will purchase certain noncore gas properties from Canadian E&P company Suncor Energy Inc., Calgary, (NYSE, Toronto: SU) for C$285 million.

The liquids-rich interests are near Taqa’s existing core area in west-central Alberta.

Suncor is continuing to divest certain noncore assets and has so far reached agreements totaling approximately $2.4 billion. Announced sales include oil and gas interests in the Rockies, in Western Canada, in The Netherlands and in Trinidad and Tobago.

Unable to secure funds for the previously announced deal, Denver-based Opon International LLC has terminated discussions with independent E&P company Delta Petroleum Corp., Denver, (Nasdaq: DPTR) to acquire a 37.5% nonoperated working interest in assets in Colorado’s Piceance Basin for $400 million.

The transaction involved a joint-venture agreement to develop Delta’s operated Vega area assets.
