Ryder Scott Company, L.P.

Algeria

North El Bormo area
Performed a potential reserve and economic study that included a multi-case development plan for a seismically defined structural feature on the Algeria-Tunisia border. Productivity had been established by test drilling in both countries.

Angola

Performed a probabilistic analysis of the exploration potential of Blocks 21 and 22 in the Kwanza basin. Also, evaluated the Kiame field.

Benin

Evaluated the Aje field.

Congo

Evaluated the following fields: Emmeraude, Masseko and Yombo.

Egypt

Western Desert
Amoun, Falak, Hayat, Kahraman C, Kenz, Khalda, Khepri-Sethos, Nader, Qarun, Ras Kanayes, Renpent, Safir, Safir North, Salam, Salam Deep, Shams, Shrouk B, Shrouk E. Tarek, Tut, Tut Deep, Yasser fields

Constructed detailed gas deliverability models for a reserves certification of all gas fields in the Western Desert operated by a major joint venture. Integrated engineering and geological studies to estimate reserves and project future net income. Performed seismic structural reviews that were integrated with petrophysical data and well-test analyses. The results from this multidisciplinary review were used to build volumetric reserves estimates for all major reservoirs and to define flow conditions during future production. Conducted engineering analysis on a field-wide basis using all available test data to validate basic well test flow conditions and to identify any possible flow barriers. Constructed an archival database of all the historical data (production, DST/MDT/RFT, pressure, PVT, wellbore diagrams, etc.) into an interactive CD-ROM format. Ultimately, analyzed each field's plan of development, recovery efficiency, aquifer size, facilities configuration and operating plans to assist the operator in optimizing the depletion plan.

Ras Kanayes field
Evaluated various wells in addition to a 2D seismic database to determine the volumetric reserves potential of the Khatatba formation within the limits of the concession. In addition, conducted well log petrophysical analysis to evaluate the possible oil reserves potential of the Alam El Bueib formation.

Equitorial Guinea

Evaluated the Alba gas field.

Gabon

Evaluated the following fields: Ablette, Assewe, East Orovinyare, Etame, Illwongue, Mwenugi, Niungo, Rembo Kotto, Tchatamba Marine, Tchatamba South, Tchatamba West and Turnix.

Mozambique

Evaluated the Pande and Temane fields.

Nigeria

Evaluated the following fields: Abana, Ejulebe, Ima, Wes and West De

Offshore Gulf of Suez

East Zeit field
Performed a detailed geological and engineering study of the original oil in place to estimate the volume of oil recoverable through existing wells and to assess drive mechanisms, recovery efficiencies and the need for additional drilling.

North July field
Evaluated the proved producing and undeveloped reserves potential of this Gulf of Suez field through a detailed engineering and geological study. Using existing well and production data along with 3D seismic information, Ryder Scott calculated a volumetric estimate of the proved producing reserves base. Integrated all area wells and seismic to evaluate the proved and probable reserves potential within the Hawara formation of a large undeveloped fault block adjacent to the producing field's wells. Determined ultimate recoverable reserves and projected net income under the provisions of the production-sharing contract.

South Africa

Evaluated the Block 9, including the Eb, Eh, Em, Es fields; Also evaluated the Fa, Fad, Fah, Far and Faz fields.

Tunisia

Evaluated several offshore oil and gas fields to develop a plan of exploitation. Reserves certification served as a basis for financing.

Sidi El-Kilani field
Evaluated the fractured Abiod formation within two wells through analyses of direct well performance and production analogs from offsetting fault blocks. The reservoir characteristics of the naturally fractured formation complicated the determination of oil in place and remaining reserves. However, a detailed evaluation of production data facilitated the reserves estimate.

West Africa

Completed engineering and geological studies of the Yombo field offshore Congo, Alba field offshore Equatorial Guinea and several fields offshore Côte d'Ivoire.
