Abstract: Hydraulic ,fracturing, is considered as an effective approach for the development of tight oil reservoirs. Unlike conventional reservoirs, after a large volume injection of the ,fracturing fluid,, the ,flowback, rate in tight oil reservoirs is considerably lower whereas the underlying mechanism explaining water retention remains unclear.

14/4/2021, · The composite flooding system composed of a surfactant and nanoparticles has shown great application potential in enhancing oil recovery. However, at present, these research studies are mainly focused on anionic surfactants. Relatively speaking, alkanolamide (CDEA), a nonionic surfactant, has the characteristics of a small adsorption amount on the rock surface, no cloud point, good …

A three-dimensional model is presented and used to reproduce the laboratory hydraulic ,fracturing, test performed on a thick-walled hollow cylinder limestone sample. This work aims to investigate the implications of the ,fluid, flow on the behaviour of the micro-structure of the rock sample, including the material strength, its elastic constants and the initialisation and propagation of fractures.

During hydraulic ,fracturing,, the ,viscosity, of hydraulic ,fracturing fluid, (HFF) should be carefully optimized considering the proppant carrying ability and filtrate loss control [4–6]. For conventional resources such as sandstone or carbonate formation, the ,viscosity, of HFF should be higher to achieve the proppant carrying capacity and ,fluid, loss control purpose.
