Hydraulic fracturing, natural fracture reactivation and resulting induced microseismicity are interconnected phenomena involved in shale gas exploitation. Due to their multi-physics and their complexity, deep understanding of these phenomena as well as their mutual interaction require the adoption of coupled mechanical and fluid flow approaches. Modeling these systems is a challenging procedure as the involved processes take place on different scales of space and also require adequate multidisciplinary knowledge. An extensive literature review is presented here to provide knowledge on the modeling approaches adopted for these coupled problems. The review is intended as a guide to select effective modeling approaches for problems of different complexity.

“…In the same time, a number of effective techniques were developed to simulate various proppant transport phenomena and the proppant placement along such fractures. These solutions and techniques are currently widely utilised in industry and were comprehensively discussed in many review papers and books by many researchers, such as Warpinski et al (1994), Mahrer (1999, Economides and Nolte (2000), and Rahman and Rahman (2010) to name a few. Nevertheless, the evaluation of the residual fracture profiles, which are directly linked to fracture conductivity as mentioned above, has received much less attention.…”

Hydraulic stimulation technologies are currently widely applied across resource and power generation industries to increase productivity of oil/gas or hot water reservoirs. These technologies utilise a pressurised fluid, which is applied inside the well to initiate and drive fractures as well as to open a network of natural fractures. To prevent the opened fractures from complete closure during production stage, small particles (proppants) are normally injected with the pressurised fluid. These particles are subjected to confining stresses when the fluid pressure is removed, which lead to a partial closure of the opened fractures.The residual fracture openings are the main outcome of such hydraulic stimulations as these openings significantly affect the permeability of the reservoirs and, subsequently, well productivity. Past research was largely focused on the assessment of conditions and characteristics of fluid driven fractures as well as proppant placement techniques. Surprisingly, not much work was devoted to the assessment of the residual fracture profiles. In this work we develop a simplified non-linear model of residual closure of a crack filled with deformable particles under remote compressive stresses. It is demonstrated that the closure profile is significantly influenced by the distribution and compressibility of the particles, which are often ignored in the existing analytical or semi-analytical models.

“…Review articles that were surveyed focused on the technical aspects related to fracking such as fracturing fluid systems and factors influencing fracture propagation (Mahrer, 1999;Rahman and Rahman, 2010;Vatsa and Wang, 2013;Barati and Liang, 2014;) and the economic aspects of these oil and gas resources such as resource availability, estimates and productivity (Clarkson et al, 2012 andMcGlade et al, 2013). These aspects are all important for the optimization of production from unconventional deposits.…”

The impacts associated with unconventional oil and gas (UOG) extraction will be cumulative in nature and will most likely occur on a regional scale, highlighting the importance of using strategic decision-making and management tools. Managing possible impacts responsibly is extremely important in a water scarce country such as South Africa, versus countries where more water may be available for UOG extraction activities. This review article explains the possible biophysical and socioeconomic impacts associated with UOG extraction within the South African context and how these complex impacts interlink. Relevant policy and governance frameworks to manage these impacts are also highlighted.
