Natural Gas Production from Tight Gas Accumulations
Natural gas production from tight, low permeability sandstones (generally rocks with less than 1/10th of a millidarcy permeability), is expected to contribute significantly to the U.S.’ future gas supply. The DOE, USGS, and other organizations have completed
resource assessments of U.S. basins with tight gas accumulations indicating that a vast (~6000 Tcf) in-place natural gas resource exists. However, there is still much that is not currently understood about the origin and development of these accumulations.

MICROSCOPIC SECTIONS OF SANDSTONE.
Conventional sandstone (left) has well- connected pores (dark blue). The pores of tight gas sandstone (right) are irregularly distributed and poorly connected by very narrow capillaries. Because of this low connectivity (low permeability), gas trapped within tight gas sandstones is not easily produced
