Saudi Arabia's Safaniya Field
Safaniya, the largest known offshore field in the world, measures approximately 39 miles along its NE-SW axis. In Aramco's concession, the field covers an area of 123,300 acres. Proved reserves are estimated to be in excess of 10 billion bbl. The field was discovered by structure drill methods and was later defined by seismic work. The discovery well was completed in Aug 1951 and production began in April 1957. During 1964, the field was produced at an average rate of 389,000 bbl/d. The average Safniya well produces 11,000 bbl/d. Some are producing at rates of 20,000 bbl/d. The average productivity index is approximately 130 bbl/d/psi. All wells are single zone completions in either the Safaniya or Khafji reservoirs. The reservoirs are part of the Wasia formation, Cretaceous in age. They are encountered at depths between 4500-5500 ft. The reservoir performance in the southern area indicates the existence of a strong water-driven mechanism. A total of 405 million bbl of oil was produced by mid-year 1964 with a corresponding pressure decline of less than 60 psi. This represents a decline of 0.15 psi per million bbl of oil produced.
