Hydraulic fracturing integrates key technologies assisting in the establishment, increase,
and stabilization of gas and oil production. In particular, the performance of the working …

The composition of hydraulic fracturing (HF) fluid poses risks to human health and the
environment by impacting drinking water sources. Fracturing fluid recovery rate is highly …

Large stores of previously inaccessible hydrocarbons have become available due to the
development of hydraulic fracturing technologies. During the hydraulic fracturing process, a …

Produced water from unconventional oil and gas reservoirs often contains non-ionic
surfactants that are added to the hydraulic fracturing fluid to facilitate water release and …

传统观点认为页岩气藏中不含硫化氢或含有微量的硫化氢, 然而在近10 年的勘探开发实践中,
已有9 个页岩气藏发现了低—特高含量硫化氢, 其中, 高—特高含量的硫化氢多出现于钙质页岩 …

Minimizing loss of injected hydraulic fracturing fluids into shale along fracture-matrix
boundaries is desired because imbibed water restricts gas production and wastes valuable …

The continuous deepening of coal-seam extraction has sharply increased both gas pressure
and content. The use of viscoelastic surfactant fracturing fluids (VESFFs) has been …

An original hybrid fluoro-surfactant DHE with double fluorocarbon chains was synthesized.
This surfactant aimed to reduce significantly the wettability of water and oil on the carbonate …

It is traditionally considered that shale gas reservoirs do not contain or contain little
hydrogen sulfide (H 2 S). However, low to extra-high content of H 2 S has been detected in 9 …

Surfactants find utility in hydraulic fracturing operations for their ability to modify rock
wettability and increase the flowback of fracturing fluid following proppant delivery. The …
