This practical volume provides a quantitative understanding of waterflooding and the engineering application of this oil-recovery method. It includes prediction of water injection rates, oil production rates, producing water/oil ratios, and cumulative oil recovery at various times in the future. Appendices include detailed mathematical derivations and example calculations.
Contents: Basic water/oil flow properties of reservoir rock • Efficiency of oil displacement by water • Mobility ratio concept • Areal sweep efficiency • Reservoir heterogeneity • Vertical and volumetric sweep efficiencies • Methods of predicting performance • Pilot waterflooding
About the Author:
Forrest F. Craig Jr., 1977 SPE president, was known internationally as author, lecturer, and energetic advocate of SPE programs. He received the Society’s John Franklin Caril Award in 1977 for his contributions to the petroleum engineering profession, especially in waterflood and reservoir performance prediction techniques, and his active participation in all levels of Society affairs. Craig received BS, MS, and PhD degrees in chemical engineering from the U. of Pittsburgh. He joined stanolind Oil and Gas Co. (an Amoco predecessor) in 1951 as research engineer with the Production Research Div. in Tulsa. During the 1960s, Craig received eight patents on miscible and thermal recovery methods and testified at 12 US regulatory agency hearings. He contributed 18 technical works to Society literature since 1952, and was involved in Society and Mid-Continent Section activities. Craig chaired the 1964 Annual Meeting Program, 1966 Transactions Editorial, and 1969 Continuing Education committees. He was 1967-68 chairman of the Mid-Continent Section in Tulsa. Craig served continuously on the SPE board since becoming a regional director in 1973. He later was a director at large. In October 1976, he became the first Society present to be installed at the Annual Meeting. Among his goals as president were improving communication among local sections through the officer visitation program, and balanced delivery of Society services to all SPE sections worldwide. He remained active in SPE-AIME affairs until his death, serving on the 1978 SPE and AIME boards, as Nominating Committee chairman, and as a member of the Executive Committee. Craig died March 8, 1978, in Tulsa at age 52.
