Argentina

El Tordillo field, Chubut
Prepared a geologic and engineering study, including log analysis and performance evaluations, to estimate producing reserves and establish parameters for behind pipe, undeveloped and secondary reserves for future exploitation and development programs. Annual reserve updates are performed to evaluate and revise the development program and to provide cash-flow projections to satisfy U.S. Securities and Exchange Commission requirements.

Entre Lomas Block, Neuquen
Conducted a complete geological and reservoir engineering study of five fields within the concession area. The study involved an analysis of seismic data plus performance and development to date. Built an economic model that was used to plan a future development program for maximizing property values.

El Mangrullo field, Neuquen
Performed an in-depth study of the reserve and deliverability potential of this undeveloped field in the Neuquen basin. Incorporated all seismic data, well logs and well-test data into this study.

Sierra Chata field, Neuquen
Prepared a reservoir simulation model study, including a detailed reservoir geological model, history match of well performance and build-up pressure and prediction runs to estimate future performance.

Other Argentine studies
Evaluated all oil and gas interests of various Argentine corporations. These major studies included both properties within Argentina and other international areas. The Argentine properties located throughout the country include many major onshore and offshore gas fields in the San Jorge, Northwest, Neuquen and Austral basins. Among these fields are Acambuco, Aguarague, Aguada Pichana, Aguada San Roque, Loma Las Yeguas, Lindero Atravesado, Cañadon Alfa, Fenix-Carina, Piedra Clavada, San Sebastian, Ramos, 25 de Mayo/Medanito, Cerro Dragon, Diadema, Chihuido de la Salina, El Trapial, Vega Pleyade, El Porvenir, Al Norte de la Dorsal, Al Sur de la Dorsal, Porcelana, Santa Cruz I, Santa Cruz II, El Cordon, Koluel Kaike, Oceano, Los Chorillos, Argo, Hidra, Campo Duran, Puesto Peter, Estacion Fernandez Oro, Rio Neuquen, Kaus, Lobo, Ara, Antares, Centenario, El Porton, Kilometro 20, Anticlinal Campamento.

Performed other studies in the Jujuy, Mendoza, Neuquen, San Jorge and Tierra del Fuego areas for exploration-and-production projects.

Brazil

Completed detailed studies of offshore fields in several Brazilian geologic basins, including Campos and Acre. Also evaluated fields offshore the northeast coast. Fields evaluated include ELPs 11, BAS64, BAS97, Merzuela, Llana, Pescada, Arabaiana, RNS-33, RNS-95, TNS-128.

Bolivia

Performed studies on recent divestiture packages in Bolivia. Evaluated fields in the Chaco area.

Colombia

Cusiana and Cupiagua fields
Conducted a detailed study to estimate volumes of original oil in place and ultimate reserves. Generated projections of sustained oil production to assist in the design of the oil-sales pipeline. The reserves certification was used to obtain project financing through a syndicate of international banks.

Las Monas area, Bucaramanga
Evaluated various working interests in three fields within this concession. Also analyzed the future exploitation of potential reserves.

Middle Magdalena Valley
Evaluated the deep-gas producing potential of a major seismically defined structural feature. Also evaluated a large producing oil field.

Rubiales field, Meta
Conducted geological and reservoir engineering studies of this shallow oil accumulation in the Llanos area of eastern Colombia to assess the economic feasibility of developing these heavy-oil reserves.

Purificacion, Revancha and Venganza fields
Prepared detailed engineering and geological studies, including cashflow analyses

Ecuador

Oriente basin
Completed geological and reservoir engineering studies of most of the fields in the Oriente basin. Some of the larger fields are the following:

Coca	Fanny	Amo
Payamino	Mariann	Capiron
Jaguar	Tarapoa	Daimi
Oso	Iro

Pacoa field, Guayas
Analyzed seismic and subsurface geology and the engineering data to forecast future oil and gas production and related economic considerations for a newly discovered field.

Mexico

Akal field, Cantarell complex
Performed reserves certification audit and economic feasibility study for nitrogen-injection project.

Peru

Analyzed exploratory program in Block 16-A concession in eastern Peru. Also studied the onshore Marañon basin for many years. Also conducted reservoir studies to estimate the reserves and future net income attributable to the offshore production in the Talara area.

Trinidad

Conducted initial studies in several major offshore fields to estimate gas reserves and their value. These periodically updated studies serve as a basis for exploitation and financing.

Venezuela

Third Operating Agreement Round
Performed geologic and engineering evaluations of several properties offered in the Third Operating Agreement Round. Provided clients with oil and gas reserve estimates, flow-stream volumes and investment schedules.

Full Ryder Scott field studies also include the following fields: Cabimas, La Concepcion, Cerro Negro, Block B2B, Pedernales, Deltana Basin Study, Dacion, Mata, Boqueron, Acema and La Paz.

Other areas

Conducted reservoir engineering and geological studies of many other oil and gas fields in South America, including those in the Magallanes basin in Chile, for various planning and investment purposes.
