The Sanaga Sud field is located 10 km northwest of the coastal town of Kribi in the central portion of the Douala basin. The Sanaga Sud A-1 discovery well was drilled in 1979 to test an eroded, paleotopographic high block composed of Lower Cretaceous sands and shales and overlain by Upper Cretaceous shales. The structure contained a prominent near-horizontal seismic amplitude event.
Drilling results showed that the amplitude event was a gas-water contact. Two appraisal wells, Sanaga Sud A-2 and A-3, were drilled in 1981. All three wells tested gas and condensate. Gross pay thickness averages 250 m, with an average porosity of 23% and an average permeability of 142 md. Total recoverable hydrocarbons for the field are estimated to be 900 bcf of gas and 4.5 million of bbl of condensate.

Giant Oil and Gas Fields of the Decade 1978-1988
The success of Memoir 14 and the worldwide interest shown for data on giant fields prompted AAPG to schedule a symposium on giant fields at the end of each subsequent decade. The 1968-78 symposium was held in Houston, Texas, April 1-4, 1979, and the papers were published in AAPG Memoir 30, December 1980.
The Stavanger Conference "Giant Oil and Gas Fields of the Decade: 1978-1988" was held in Stavanger, Norway, September 9-12, 1990, and is a continuation of the Giants of the Decade series.
Scientific studies and projections of future world energy demand indicate that although alternative-energy fuel sources must be actively pursued and developed, there also must be adequate petroleum supplies to bridge the gap. For the international petroleum industry, the years covered by this conference, 1978-88, were complex. They were years of boom and bust. The world's energy consciousness was boosted sharply by the effects of the 1979 Iranian revolution and the resulting embargo, which sent world oil prices to record heights. Global petroleum exploration soon surged, leading to the industry's all-time drilling high in 1981. Then came the oil price collapse in 1985, and the following years were characterized by falling oil prices and drastic budget cuts for exploration and development.
Although exploration dropped sharply during the latter part of the decade, there was a steady flow of giant oil and gas field discoveries. Using the giant field designation criteria of 500 million bbl of oil recoverable for fields in Asiatic Russia, North Africa, and the Middle East,
