Four reservoirs containing dispersed gas were examined for their coproduction potential. Reservoirs in Port Acres field (Texas) and Ellis field (Louisiana) produce from the Hackberry member of the Oligocene Frio formation, and two reservoirs in Esther field (Louisiana) produced from the lower Miocene Planulina zone. Log-pattern and lithofacies maps, together with stratigraphic position, suggest that the reservoirs are in ancient submarine-fan deposits. Dip-elongate, channel-fill sands are characteristic; reservoir sands pinch out along the strike. Growth faults, common in the submarine slope setting, form undip and downdip boundaries, producing combination traps. In Ellis field, coproduction accounts for 300 Mcf/D (8.5X10/sup 3/ m/sup 3//d) of gas. Port Acres field contains the largest remaining reserves, but other technical and economic factors limit coproduction potential there. Recent drilling has extended primary production and delayed coproduction in the Esther field.
