Cano Limon--New Giant Oil Field in Colombia
Donald R. Lindsay, George W. Kendall
Discovery of the billion-barrel Cano Limon field in July 1983 established the Llanos basin in eastern Colombia as a major oil-productive region. Initial production in December 1985 was 30,000 BOPD from two wells, with full production expected by mid-1986 when a pipeline to the coast is completed.
The accumulation has updip closure against convergent sealing faults. The main reservoir is the Eocene Mirador formation, with average net pay of 155 ft (47 m) consisting of unconsolidated sands with up to 7 darcies in-situ core-measured permeability at an average depth of 7,300 ft (2,225 m). The sands were derived from the Guyana shield to the east and deposited in a westerly prograding alluvial-deltaic system. Smaller accumulations occur in Oligocene and Cretaceous sands deposited in shallow marine to deltaic environments.
