  To economically produce from very low permeability shale formations,
hydraulic fracturing stimulation is typically used to improve their
conductivity. This process deforms and breaks the rock, hence requires the
geomechanics data and calculation. The development of unconventional reservoirs
requires large geomechanical data, and geomechanics has involved in all
calculations of the unconventional reservoir projects. Geomechanics has
numerous contributions to the development of unconventional reservoirs from
reservoir characterization and well construction to hydraulic fracturing and
reservoir modeling as well as environmental aspect. This paper reviews and
highlights some important aspects of geomechanics on the successful development
of unconventional reservoirs as well as outlines the recent development in
unconventional reservoir geomechanics. The main objective is to emphasize the
importance of geomechanical data and geomechanics and how they are being used
in in all aspects of unconventional reservoir projects.
