15/9/2019, · However, a new type of self-propping fracturing technology is proposed in this paper without any solid proppant carried in the process of fracturing fluid injection. Because the fracturing fluid itself will transform into solid proppants when the fracturing fluid reaches the target reservoir under certain conditions, which produces sufficient strength to resist fracture closure stress.

19/11/2014, · As mentioned above, the clear fracturing flowback fluid is mainly composed of VES which is usually cationic ammonium surfactant and AOS is anionic. When cationic and anionic surfactants are used together, the strong electrostatic attraction leads to the adsorption of more surfactant molecules on the oil/water interface [36] , which results in the appearance of lowest IFT in mixed catanionic systems.

2021 Hydraulic Fracturing Technology Showcase

To reduce fluid loss encountered during the hydraulic fracturing process, NatureWorks has released a new polylactic acid (PLA)-based degradable polymer called Ingeo DH1900 for downhole applications. Ingeo DH1900 can be pumped downhole as fine, discrete particles that quickly change into a thick, degradable material at the targeted site.

Hydraulic ,fracturing fluid, (HFF) additives are used to enhance oil and gas extraction from unconventional shale formations. Several kilometers downhole, these organic chemicals are exposed to temperatures up to 200 °C, pressures above 10 MPa, high salinities, and a pH range from 5–8. Despite this, very little is known about the fate of HFF additives under these extreme conditions.
