Index / Gas (Tight) Sands / Exploration

With the decline of production and increase in demand of fossil-fuel, economically producing gas from
unconventional sources (tight gas, coal bed methane (CBM), and gas hydrate) is a great challenge today. The large volume and long-term potential, attractive gas prices and
unprecedented interest in world markets, brings the unconventional gas into the forefront of our energy future. Tight gas exists in underground reservoirs with microdarcy-range permeability and have a huge future potential for production. Four criteria that define basin-centered gas accumulations, including low per... More →

Index / Gas (Tight) Sands / Exploration

Tight gas sands are defined as sandstone formations with less than 0.1 millidarcy permeability. The millidarcy is a unit of measurement related to the ability of a fluid to pass through a porous medium. The degree of permeability depends upon the size and shape of the pores, the size and shape of their interconnections, and the extent of the latter. It has been estimated that total-gas-in-place in the United States may exceed 15,000 trillion cubic feet.
