Trees harvest the fruits of marginal fields

摘要

GE Oil and Gas last month sold the first in its latest line of subsea trees, designed to be used at oil and gas sites previously too expensive to develop.rnSubsea trees sit on the sea bed to control the flow of oil or gas out of a well, although they often offer other functions such as chemical injection points and well monitoring.rnShell UK bought the first VetcoGray SVXT S-series tree from GE to use in the Southern North Sea, an area which requires low-cost techniques to profitably extract the remaining gas reserves.
