Water-based fracturing fluids are among the most common fluid types used in hydraulic operations. However, these tend to cause damage water-sensitive formations. Foam comprises a small amount of base fluid, and compressible gas such as carbon dioxide nitrogen has emerged more ecologically friendly option fracture is an attractive since it low density high viscosity. The applicability foamed fra...

A hidraulikus rétegrepesztés egy rétegkezelő eljárás, melynek célja, hogy az alacsony hozammal rendelkező kutak produktivitását megnövelje. szivattyúzás megszűnése után, a rétegnyomásnak megfelelően repedés újra összezár, ezáltal proppant szemcsék deformációt szenvednek (megakadályozzák visszazáródást/kitámasztják repedést), illetve beágyazódnak felszínébe, ami jelentősen csökkenti kialakított ...

Hydraulic fracturing is a technique used to stimulate the production of conventional and unconventional hydrocarbons, being this type resource strategic part Argentina’s energy reserve. The procedure consists in injecting fluids at high pressure into wellbore create fractures formation that later act as highly conductive paths through which hydrocarbons can flow. Since releasing causes fracture...

Horizontal wellswith multi-cluster fracturing technology is an effective approach to exploit unconventional hydrocarbon reservoirs. The on-site diagnosis results indicate that fractures always tend propagate unevenly due stressinterference, therefore it very essential study the effect of parameters on fracture propagation unevenness. In this paper, model (UFM, Unconventional Fracturing Model) u...

Abstract Hydraulic fracturing is a widely employed well stimulation technique in which synthesized fracking fluid pumped into the bore at high pressures to propagate fractures rock formation matrix for hydrocarbon production. Proppant being one of essential component used keep hydraulically induced open and conductive by acting as mechanically strong support particle. operations are gradually s...

This experimental study investigates the unclogging process of a propped fracture previously clogged, using synthetic dynamic load. Pressure oscillations inside are expected to flush out fine particles blocking flow. Laboratory experiments presented: fractures clogged with crushed natural sand; after applying load, significant increase intrinsic permeability is observed. The highest recovery ra...

For the purpose of cost management, many companies and research institutions have carried out technical on replacement ceramic with quartz sand as proppant. However, few studies systematically short-term long-term conductivity evaluation experiments for proppants different particle sizes. It is urgent to conduct sand, optimize fracturing design based experimental results. The key indicator effe...
