Ventura field, California, is approx. 6 miles long and 1 mile wide at the widest point. The reservoir-rock properties generally become less porous and less permeable with depth. Ventura field has over 1,200 producing wells and a 3,420-acre proved productive area. The deep zones have reservoir pressure ranging from 500 to 2,500 psi. Initially, the deep zones were excluded from waterflood planning, because of their low permeability. In 1963, a water-injection test was started in the 6th (N) zone at 12,000 ft. Satisfactory injection rates and good injection profiles were achieved. Subsequent water injection into an up-structure 5th (N) zone well indicated similar favorable results. To date, 30 million bbl of water have been injected into the 5th and 6th(N) pools. Currently 60,000 bwpd is being injected at 3,000 psi. Deep-zone plans call for ultimately injection 120,000 bpd at pressures up to 4,500 psi. The deep-zone problems, including high-pressure pumps, water supply and water treatment, and monitoring an alarm are described.
