More Information
Summary:A method for hydraulic fracturing of a subterranean formation includes injecting an oil-based fracturing fluid into the subterranean formation through a well. The method also includes injecting a second fracturing fluid, for example a water-based fracturing fluid, into the subterranean formation through the well after completion of the injection of the oil-based fracturing fluid. Un procédé de fracturation hydraulique d'une formation souterraine comprend l'injection d'un fluide de fracturation à base d'huile dans la formation souterraine à travers un puits. Le procédé comprend également l'injection d'un second fluide de fracturation, par exemple un fluide de fracturation à base d'eau, dans la formation souterraine à travers le puits après achèvement de l'injection du fluide de fracturation à base d'huile.
