Bolivia - Performed complete facility inventory in preparation for sale of selected properties for YPF Bolivia. Provided a physical inventory, a report on all producing leases, and a depreciated valuation of the equipment.

Brazil - Conducted a reserve certification of the Petrobras-operated Barracuda and Caratinga Fields in the deepwater region of the Campos Basin. These 2 fields lie in 600 to 1,400 meter water depths and produce from up to 7 different Oligocene to Eocene age turbidite reservoirs. Work consisted of an independent volumetric evaluation to estimate the original oil-in-place and an engineering analysis incorporating reservoir simulation of the existing pilot production and the full field development plan to estimate the ultimate recoverable reserves in each of the reservoirs through the end of the Production Sharing Agreement.

Colombia - Performed a review of the client's exploration and development program for the Putumayo Basin. Addressed tectonic models, seismic interpretation, and other exploration considerations affecting prospect risks.

Colombia - Estimated reserves and future revenue for Abarco, Cocorna, Girasol, Jazmin, Nare, Teca, Under River, and Velasquez Fields located in the Middle Magdelena Basin on behalf of Saba Petroleum Company; Omimex de Colombia, Ltd.; and Mansarovar Energy Colombia, Ltd. These fields contain a combination of heavy oil under steamflood and intermediate gravity oil under primary and secondary recovery.

Ecuador - Estimated reserves and future net revenue for the Blocks 14, 17, and Shiripuno Concessions located in the Oriente Basin for Vintage Petroleum, Inc. These fields produce primarily from the Hollin, Upper Napo, and Tena Reservoirs. Work included an integrated study of geological, geophysical, petrophysical, and engineering information. Economic model incorporated terms of production sharing agreements and risk service contract and an optimization of the development drilling schedule to maintain maximum oil production.

Ecuador - Evaluated oil and gas properties in Pacoa Field, Progreso Basin, including a field operations review of the properties and estimates of the reserves and future revenue.

Peru - Performed engineering and geological studies of 13 onshore and offshore fields located in the Talara Basin. This area is characterized by complex geology with many wells producing by artificial lift. Our estimates of reserves and future revenue were used as a basis to evaluate the potential acquisition of these properties from PetroPeru, the national oil company of Peru.

Peru - Conducted engineering and geological studies of 15 Occidental-operated oil fields located in the Maranon Basin within the jungles of northern Peru. Typical wells produce large volumes of low-gravity oil with high water cut using electric submersible pumps. Our estimates of reserves and future revenue were used as a basis to evaluate the possible purchase of the operating contract for these properties.

Peru - Evaluated gas, condensate, and plant liquid reserves and provided engineering services for Aguaytia Field in the Ucayali Basin in central Peru to investigate the feasibility of installing a gas plant, 155-megawatt electric power generation plant, and the associated power transmission line across the Andes mountains.
