Nonassociated gas potential of San Juan basin considerable
- U.S. Geological Survey, Lakewood, CO (US)
This paper reports on the San Juan basin, a major hydrocarbon producing province in the Rocky Mountains. Cumulative production for both the New Mexico and Colorado parts of the basin, as of Jan. 1, 1983, was 190 million bbl of oil, 14 tcf of nonassociated gas, 425 bcf of associated gas, and 60 million bbl of condensate. Ultimate recovery of nonassociated gas was estimated to be 23 tcf. On the Four Corners platform and Chaco slope, oil and associated gas occur in structural and stratigraphic traps. In the generally structureless central basin, nonassociated gas and condensate occur in underpressured sandstone reservoirs. Hydrodynamics and low permeability are responsible for trapping the gas in this unusual type of accumulation. Coal beds have been considered as the source rocks for much of this gas.
