West Delta Deep Marine — Offshore Mono Ethylene Glycol Injection

In 1999 INTECSEA (Previously INTEC) commenced a FEED study in a concession called West Delta Deep Marine (WDDM), offshore Egypt in the Mediterranean Sea. The development was to be operated by the Burullus Gas Company, a Joint Venture comprising BG Egypt, Edison Gas and EGPC (the Egyptian General Petroleum Company). Since that time Edison Gas have sold their share to PICL (Egypt) Corporation Ltd (Wholly owned by PETRONAS). The development was the first deepwater development offshore Egypt, an area with no experience in deepwater developments with little associated infrastructure. The development was also to be pioneering as it was, at that time, one of the longest tie-backs to shore at 90 km initially with the Scarab /Saffron fields. Since those early days, INTECSEA have continued working alongside Burullus Gas, delivering a number of Phases of the development, with the expansion being further, 105 km, from shore and in deeper water, 1024 m. This article describes our work associated with the need to provide reliable subsea Mono Ethylene Glycol (MEG) injection and some of the issues experienced from those early days to the present.
