This paper describes the project evolution, from the first study to the implementable concept of energy production using the associated gas of two onshore facilities in Tunisia. Despite complex composition, high CO2, high H2S, and relatively low quantities, a solution was developed successfully.

This paper addresses a “conceptual model” for an overfill-protection program, based on a recent industry example. Key portions of the programmatic and overfill-equipment aspects will be addressed.

The Polymer injection project on the Dalia field, a high permeability sandstone reservoir deep offshore Angola, is a world first in both surface and subsurface aspects. A phased approach was used to manage risks, along with development of new monitoring approaches.

Through a range of experiments the authors demonstrate that small amount of H2S can be beneficial in reducing corrosion in 3% Cr steel.

The three papers in this issue address safe design of facilities, use of the chemical acrolein in an offshore environment, and the integration of reservoir and pipeline modeling to capture the variations in reservoir-flow dynamics with changes in the surface-network operating conditions.

This paper describes a gas-hydrate model for oil-dominated systems, which can be used for the design and optimization of facilities focusing on the prevention, management, and remediation of hydrates in flowlines.

Offshore production systems can be impacted negatively by numerous problems attributed to bacterial activity, associated hydrogen sulfide and biogenic iron sulfides, and mercaptan production. Acrolein provides a distinctive all-in-one chemical solution to assist in resolving these problems.

This paper reviews the key areas for facility designers and engineers to include when designing facilities to ensure safe facilities. Use and incorporation of the principles outlined in this paper should enable engineers and designers to build safe facilities that reduce the risk of major incidents.

Good early production caused an FPSO to reach the design topside limit with only five wells connected. A study was undertaken to determine how bottlenecks could be reduced to allow greater production without compromising process safety.

Roughly one-half of global gas reserves are considered stranded gas--uneconomical because of the remote location of potential markets, lack of economic transportation and infrastructure, or the lack of conversion technology. An FPSO with gas to liquids conversion is an option for stranded gas.
