Paragon and ChevronTexaco work to reduce gas flaring

Houston-based Paragon Engineering Services Inc. is supporting ChevronTexaco on a front-end engineering contract for five projects to support reducing routine gas flaring in Angola.

Houston-based Paragon Engineering Services Inc. is supporting ChevronTexaco on a front-end engineering contract for five projects to support reducing routine gas flaring in Angola.

As part of its Area "A" gas management program in Angola, ChevronTexaco subsidiary and block 0 operator, Cabinda Gulf Oil Co. Ltd. (CABGOC), and partners, Sociedade Nacional de Combustíveis de Angola, Elf Petroleum Angola, and Agip Angola Ltd., awarded Paragon a contract that includes an integrated effort in the offshore Takula, Wamba, Numbi, and Malongo areas as well as some onshore areas.

The main efforts include a newbuild gas processing platform in the Takula area, modifications to existing platforms in the Takula, Wamba, and Numbi areas, and the newbuild onshore Cabinda gas plant.

Four existing gathering station (GS) facilities in the Takula, Wamba, and Numbi areas will be modified to recover low-pressure flared gas. Today, most of the gas in this area is sent to an existing artificial lift platform (ALP) and compressed for gas lift. Eventually, the gas will instead be sent to ALP and the new-build Takula gas processing platform for compression, sweetening, and removal of raw natural gas liquids (NGLs). The NGLs will be transported via existing pipelines to the new onshore Cabinda gas plant, while the residue gas will be sent via existing pipelines to a gas injection system.

Several platforms in the Malongo area will also be modified to recover gas that is currently flared. Malongo gas will be collected and sent to the existing offshore NGL plant and then on to the new gas injection storage system.

In a separate effort, the Fox platform in the Malongo area will be modified to receive high-pressure gas from the Benguela Belize field in block 14 through a new pipeline. This gas will be distributed to outlying well platforms for reinjection and storage.

According to Paragon, as currently envisioned, this project ranks as the company's second-largest current effort in terms of work volume.

Paragon's scopes of work include front-end engineering and design for the newbuild components as well as detailed design for some modification efforts.
