Meanwhile, it is demonstrated that the aqueous flowback efficiency depends upon flowback timing, pressure difference, initial permeability and bedding direction. The flowback efficiency of matrix, natural fracture and artificial fracture cores could be less than 7%, less than 30% and less than 15%, respectively.

This idea to investigate the shut-in ,timing, effect is motivated by the fact that in the field, shut-in can take place either immediately after hydraulic ,fracturing, but before the first ,flowback, (i.e., pre-,flowback,) or sometime after the first ,flowback, (i.e., post-,flowback,). The ,timing, of shut-in …

Results show that the ,flowback, data collected in the blowout stage cannot be neglected, otherwise the effective fracture volume is relatively smaller. The proposed method provides the technical support for the evaluation ,of fracturing, performance of shale gas wells with the use of ,flowback, data.

GSA Critical Issue: Hydraulic Fracturing
GSA Critical Issue: Hydraulic Fracturing

Hydraulic ,fracturing, is a technological process used in the development of natural gas and oil resources. Used commercially since the 1940s, it has only relatively recently been used to extract gas and oil from shales and other tight reservoirs economically. Development of lower cost, more effective ,fracturing, fluids (1), with horizontal wells

Stimulation engineers maintain a constant rate of fluid injection. The volume injected includes the additional volume created during fracturing and the fluid loss to the formation from leakoff through the permeable wall of the fracture. However, the rate of fluid loss at the growing fracture tip is extremely high.

However, the ,timing, (Fig. 2 and Table S1) and the presence of UCMs and 2-BE in ,flowback,/production waters in PA are consistent with shale gas activity as the most probable source. We also conclude that the foam identified from the homeowner wells was likely derived from either the UCM hydrocarbons ( 28 ) or 2-BE (a known surfactant).

GSA Critical Issues - Hydraulic Fracturing

Hydraulic fracturing, (also known colloquially as “fracing,” or “fracking,”) is a technique used to stimulate production of oil and gas after a well has been drilled [15]. It consists of injecting a mixture of water, sand, and chemical additives through a well drilled into an oil- or gas-bearing rock formation, under high but controlled pressure.
