One hypothesis is that the space flight induced headward ,fluid, alters posterior ocular pressure and volume and may contribute to visual acuity decrements. Therefore, we evaluated venoconstrictive thigh cuffs as a potential countermeasure to the headward ,fluid, shift-induced effects on intraocular pressure (IOP) and cephalic vascular pressure and volumes.

Fracturing fluid, trapped in the micro-nano induced cracks is difficult to ,flowback, due to the strong capillary force, but under the capillary force, the liquid can move from induced cracks to small pores, which can greatly increase the main gas flow channel, and thus after well shut-in for a time, shale gas can flow out of the formation.

Flowback, is the portion of the injected ,fracturing fluid, that flows back to the surface, along with oil, gas, and brine, when the well is produced. An estimated 90% of ,flowback, in the United States is disposed of into deep EPA-licensed Class II disposal wells , with the remaining less than 10% reused, evaporated, used for irrigation, or discharged to surface streams under an NPDES permit.

1/2/2021, · Hydraulic ,fracturing, processes usually consist of the injection of a ,fracturing fluid, (FF), the introduction of proppants, and ,flowback, of the FF. The introduction of proppants includes a time period in which pumping is stopped and the proppants are injected into the produced fractures.

The ,fracturing, takes place at the start of the wellbore's life cycle. The injected ,fluid, is often water, and it usually contains various chemical additives and a proppant, like sand, to keep the fractures open so oil and gas can flow to the well. For more information on hydraulic ,fracturing, fluids, see FracFocus.ca.
