Wind power could be used to pump oil from remote offshore fields in the way windmills were once used to pump water from wells in arid West Texas. The offshore wind idea was offered by DNV GL, which did a study showing that the wind offshore Norway is strong and steady enough year round to provide the electric power needed to inject 45,000 B/D of water into a remote offshore field in water 200 m deep.
The study, which is the product of a seven-company joint industry project (JIP) created by the Norwegian classification and standards setting body, examined ways to move the source of power close to where it is needed. It is a natural idea for the offshore Europe region, a leader in the growth of offshore wind capacity, which is rising 37% a year.
“Wind on floating structures is developing rapidly and we see a need for lower costs in oil and gas,” said Johan Sandberg, segment director for floating offshore wind, DNV GL. The JIP is now talking to oil producers about working with them on the next stage, which will move from a tabletop test using available data to laboratory testing with a goal of preparing for an offshore test.
The results presented at OTC suggest that there are places where floating turbines can significantly reduce the cost of powering injection pumps. The results reflect the reality in a single field, located 33 km away from its host platform and from land. The JIP considered the cost of floating an unstaffed structure, with a water processing plant on board treating the water for injection. The floating wind turbine saves both the cost of long lines for electricity and seawater for injection from the host....
