Peer Reviewed Papers - Overview

This month's papers address one of the effects of an alkaline-surfactant-polymer flood on changes to the emulsion rheology, the conservation of flared associated gas from two onshore Tunisian fields despite high H2S and CO2 content, and minimizing HSE impacts for pipelines in the Baltic Sea.

Welcome to the peer-reviewed section of the June 2012 Oil and Gas Facilities magazine. The diversity of the magazine’s content continues to surprise me. The general theme for this issue is environmental applications. I hope you find the following papers interesting and enlightening.

Prediction and Experimental Measurements of Water-in-Oil Emulsion Viscosities DuringAlkaline/Surfactant Injections deals with one of the effects of applying an alkaline-surfactant-polymer flood with emphasis on the changes to the emulsion rheology. The discussion also includes the role of surfactant on the interfacial tension of emulsions in the formation. Understanding the effects of the emulsions is essential for pump and pipeline design, as well as for handling flow‑assurance issues.

Flare-Gas Recovery in Tunisia—From Liability to Value describes the conservation of flared associated gas from two onshore fields. Despite its complex composition, high carbon-dioxide content, high hydrogen-sulfide concentration, and the relatively low quantities of available flared gas, a technically and economically viable solution was successfully developed. The pressure from environmental and political organizations helped to justify new alternatives to flaring of the gas.

Minimizing HSE Impacts During Design and Construction of a Major Gas Pipeline Through the Baltic Sea describes the process that was undertaken to ensure that two major pipelines through the Baltic Sea have minimal impact on the environment and human activities. Due consideration was also given to ensuring the health and safety of construction personnel and minimizing the environmental impact during construction.

Thanks go to the peer-review editors for review of these papers and thank you very much for your continued support and participation in the Oil and Gas Facilities magazine. I’m confident you’ll enjoy this issue.
