Vacuum deaeration was successful in reducing the oxygen content of 26,000 bpd of injection water from 9 ppm to 0.5 ppm at an operating cost of approximately $2.40 per day in the Pan American Petroleum Corp.- operated Northwest Witcher Waterflood Unit (NWWFU), Oklahoma. The total investment for equipment was approximately $9,300. The NWWFU is located in the city limits of Oklahoma City and had been in operation approximately 18 mo. when numerous leaks in the injection lines began to occur due to extensive pitting corrosion. Initially, the high corrosion rates (100 MPY) were attributed to oxygen saturated (7-9 ppm) injection water, and since the standard methods of oxygen removal seemed economically unattractive, it was decided to attempt vacuum deaeration. Although mechanical deaeration had been used sparingly but successfully in the past, records of its use are scanty. An experimental vacuum deaerator was fabricated and installed in Dec. 1964. Various modifications were completed in May 1965, resulting in trouble-free operation. Although the severe initial corrosion rates have now been attributed to another cause, this paper concludes that vacuum deaeration can successfully and economically by used to reduce the dissolved oxygen content of water.
