Tchibouela Marine

Location

The Tchibouela Marine Oil and Gas Field is located offshore in the Republic of the Congo. Specifically, it is situated within the Tchiboula II concession, with approximate coordinates of -4.9265, 11.6477 (WGS 84).

Operator and Ownership

The field is operated by Perenco, a global oil and gas company. The ownership structure is as follows:

• Perenco: 40.0%
• National Petroleum Company of the Congo (SNPC): 20.0%
• Nor Energy AS: 10.0%
• Continent Congo SA: 10.0%
• Other stakeholders: 20.0%.

Discovery and Production

The Tchibouela Marine Oil and Gas Field was discovered in 1984. The Final Investment Decision (FID) year is not specified, but production began in 1987.

Reserves

As of the available data:

• The remaining recoverable reserves of crude oil and condensate are approximately 33.63 million barrels (as of 2021).
• The estimated ultimate recovery (EUR) for hydrocarbons is around 200 million barrels of oil equivalent (boe) (as of 1994).

Production

Historical production data indicates that the field produced around 20.71 million barrels of crude oil and condensate per year in 1995.

Seismic and Exploration Activities

Recently, Perenco and the Republic of Congo's state-owned Société Nationale des Pétroles du Congo (Congorep) completed a 3D seismic acquisition campaign in the area, including the Tchibouela II concession. This campaign aimed to assess the geology at subsurface depths of 2,000 to 3,000 meters, following the discovery of hydrocarbon reservoirs on neighboring permits.

Operational Details

The field has been in operation since 1987, and despite some operational challenges such as working around existing platforms, local shipping activity, and variable weather conditions, the seismic acquisition program was successfully completed. The seismic acquisition vessel used a 6,000-meter-long, 900-meter-wide cable array with a rotation radius of 4 kilometers.

Additional Context

The Tchibouela Marine Oil and Gas Field is part of the broader oil and gas extraction activities in the Republic of the Congo. It is one of the significant fields contributing to the country's oil and gas production, managed under the joint venture between Perenco and the national oil company, SNPC.
