Exploration and development of hydrocarbon resources in Pacific basins of Ecuador--summary
The Pacific basins of Ecuador have excellent geologic characteristics for the accumulation of hydrocarbons. Geologic, seismic, gravity, and magnetic surveys provided a basis for exploratory drilling in the provinces of Esmeraldas, Manabi, and Guayas. Exploratory drilling in the Santa Elena Peninsula has resulted in the discovery of the Ancon, Petropolis, Santa Paula, Concepcion, Certeza, and other oil fields. In 1970, the Amistad gas field was discovered in the Gulf of Guayaquil. Shows of gas and oil were obtained in stratigraphic units penetrated in wildcats elsewhere in Guays Province. The best petroleum prospects of the Ecuadorian littoral zone are placed offshore in the Gulf of Guayaquil. Important gas accumulations are present at depths between 9,000 and 14,000 ft (2,740 to 4,270 m), principally in the Miocene Subibaja Formation. Cumulative production of oil in this area to June 1974 was 106,300,000 bbl. Although data on gas reserves are scarce, proved reserves in the Gulf of Guayaquil are estimated at 145,111 MMcf, and probable reserves at 373,536 MMcf.
