Future Potentials of Unconventional Gas

Challenges and Opportunities

Abstract

Conventional gas sources will not be able to satisfy the future energy demand and thus unconventional gas sources (tight gas, shale gas, and coalbed methane) are expected to be a major component of the energy outlook. In the long term, methane from gas hydrates will add to the unconventional production of natural gas. At present, gas hydrates are only a research theme and there is no existing project on production of natural gas from gas hydrates. In terms of technological development, only horizontal well and fracturing have been used to produce natural gas from unconventional reservoirs. While these technologies will continue to produce more natural gas from ...
