在非常规储层（例如，富含有机物的页岩、致密砂岩或白垩）中，低孔隙度和渗透率抑制流体通过基质流动到生产井。在高压下注入流体和支撑剂导致原位裂缝的再活化和新的水力裂缝的产生。这些裂缝为油井提供了高渗透率的管道，从而允许从其他不可开采的地层进行可行的开采。量化这种变形的程度和类型有助于确定井的排水能力，从而确定生产潜力。用于量化这种变形的有用技术包括流动和变形的数值建模以及注入的微震监测（参见麦克斯韦等人，2015年）。
In unconventional reservoirs (e.g. organic rich shales, tight sandstones, or chalks) low porosity and permeability inhibit fluid flow through the matrix to a producing well. Fluid and proppant injection at high pressures leads to reactivation of in situ fractures and the generation of new hydraulic fractures. These fractures provide high permeability conduits to the well, thus allowing viable production from otherwise unproducible formations. Quantifying the extent and type of this deformation helps to define the drainage capability of a well and thus the production potential. Useful techniques for quantifying this deformation include numerical modeling of flow and deformation and of microseismic monitoring of the injection (see Maxwell et al., 2015).
