Abstract:
Wells drilled in this area encounter the typical Gulf Coast sequence of sedimentary facies which begins with a massive sand facies, followed by alternating sands and shales below which is found the deep water shale facies. Numerous east-west trending south dipping faults with anticlinal closures on the downthrown side control most of the hydrocarbon accumulation. Electric log signatures show that typical deltaic depositional environments are found in these fields with distributary mouth bars, channel sands, crevasse splays and subdeltas being common. These sand bodies are limited in areal extent and separated from each other. Sands originating in the same genetic environment have similar log signatures and thus have the potential of being misrepresented as the same sand though they are different and separated bodies and should be individually tested for hydrocarbon production. The existence of numerous thin bypassed stratigraphically isolated sands and deeper Middle Miocene sands offer excellent opportunities for successful commercial exploitation for additional reserves of oil and gas with technical advances combined with the current high cost of energy in the world market.
