GoM projects to favor electric flowlines, low dosage inhibitors for hydrate prevention

Electrically-heated equipment and Low Dosage Hydrate Inhibitors (LDHI) are likely to become the key flow assurance technologies in the Gulf of Mexico (GoM), Stephen Hamilton, lead flow assurance engineer at Premier Oil said.

More than half of the projects starting up in the Gulf of Mexico over the next two years will be using subsea tiebacks, operating in water depths of over 2,000 metres below the sea level.

The high pressures and low temperatures in deep water environments support the formation of hydrates, making this a crucial development area for flow assurance.

According to Giancarlo Mangiafico, project coordinator at Eni Petroleum, hydrates have often been found in deep waters a year after a well has stopped operating.

Royal Dutch Shell has taken the final investment decision (FID) to develop the Appomattox deepwater field in the Gulf of Mexico, it said July 1.

This decision authorises the construction and installation of what will be Shell’s eighth and largest floating platform in the Gulf of Mexico.

Oil will be produced from the Appomattox field and the neighbouring Vicksburg field. Shell said it expected average peak production to reach some 175,000 barrels a day.
