Chevron will be using a new enhanced recovery technology to increase production at its Captain field offshore the United Kingdom. Six long-reach horizontal wells will be drilled to inject polymerized water into the reservoir in a flooding program designed to boost the oil recovery rate by 5% to 7%. The 20-year-old field has been waterflooded for years. The polymer will be less susceptible than injected water to coning, in which water spreads unevenly in the reservoir and bypasses potentially recoverable oil. Polymer injection is expected to reduce the water cut in the producing wells. Chevron is the operator with an 85% interest in the field. Dana Petroleum holds the remaining stake.
