It is shown that stress fields within the earth are the principle control for hydraulic fracture direction in horizontal shale gas wells. Hydraulic fracturing is a process of increasing permeability within gas shales and involves a sophisticated organization of technology, good planning and proper management of equipment over a very short time period to be successful. The direction and extent of the induced fractures can be determined in near real-time at the well site via application of earthquake seismology theory in a now common process known as frac mapping. Next to the horizontal lateral azimuth, the total volume of slurry pumped into the well is a major factor in determining well EURs. Vertical fracture growth can be controlled and is important in concentration of the slurry within the main zone target zone that has the high TOC and porosity. Cemented casing with perforations is currently the most used method for zone isolation. New open-hole sleeve packers may eventually provide more flexibility in fracture design while also providing a means for refracturing multi-stage fractured horizontal wells, a technique not now commonly available. Multi-Stage fracture design requires incorporating rock properties with fracturing effect simulations and then verifying results using 3D reservoir simulations. Maximizing the gas recovery factors and EURs can be accomplished through use of closely spaced laterals with inter-fingered fracture stages and exploiting the stress shadow fracturing phenomenon. Even greater EURs may be possible if the wells can be refractured thereby opening up additional permeability channels. Shale gas development has progressed in an environmentally sensitive manner within the U.S. and will continue in this manner. During the past ten years, all of these technologies have been either newly developed or were the advancement of existing technology with modifications. The opportunity exists to take these proven technologies to other areas of the world for exploitation of shale gas reservoirs.
