  • Publication number: 20230034507
    Abstract: A method of stimulating fluid production from a well includes defining a candidate stimulation treatment including injection of a slurry comprising acid and proppant, based on measurements of the formation. Fracture propagation and fluid transport in the formation are simulated using particle-in-cell techniques. Etching of rock by the injected acid is simulated. Rock compaction is simulated, including compaction around etched and propped portions of a fracture. A predicted fluid conductivity for acid-stimulated fracture is calculated based on the simulation of fracture geometry and a final stimulation treatment is defined based on the predicted fluid conductivity. An acid-proppant slurry is injected into the formation according to the final stimulation treatment.

  • Publication number: 20220364454
    Abstract: Design method for hydraulic fracturing of a reservoir is presented that maximize well production rates and minimize proppant flowback. The method comprises employing computer simulators that analyze a fracturing treatment design in the context of well properties, reservoir properties, fluids and proppants, and calculates a critical filtration velocity for a proppant pack. If the fluid flow velocity in the fracture exceeds the critical filtration velocity, there is a risk for proppant flowback. The method is applicable to wells that have not yet been fractured, as well as those that have previously undergone a fracturing treatment.

  • Patent number: 10421897
    Abstract: This method is designed to facilitate the well treatment with the possibilities for non-uniform/heterogeneous proppant placement in the extended and branched fractures produced by hydraulic fracturing. The essence of the method is to inject a proppant-bearing gel into the wellbore drilled into a productive formation. The low-viscosity fracturing fluid is injected into the wellbore together with the gel fluid (simultaneously or in turns). The method also provides for the injection of gas into the proppant-bearing gel and/or the low-viscosity fluid. The gas can be injected upstream of the junction point, at the junction point, or downstream of the junction point of the flows of the proppant-bearing gel and the low-viscosity fluid. The method further provides for the division of the gel fluid into the separate agglomerates with their subsequent injection into the fractures in the subterranean formation to form the proppant structures in the fracture.

  • Publication number: 20180094186
    Abstract: The disclosure relates to well systems for producing various fluids, in particular for producing the fluid from the hydrocarbon-bearing formation using hydraulic fracturing. According to the method of hydraulic fracturing of the formation intersected by the wellbore, the wellbore is provided, and the step of injecting the fracturing fluid without proppant to the wellbore is performed to form a fracture in the formation. Then, the step of injecting the fracturing fluid containing a mixture of fine particles and shrinkable polymer fibers is performed and the triggering mechanism is implemented, which causes the shrinkable polymer fibers to shrink, then the flowback of the fracturing fluid is provided and the fracture is cleaned. The provided method allows reducing the impact of the fracturing fluid flow on the proppant pillar geometry, as well as keeping the proppant in a consolidated state inside the agglomerates, pillars, or clogs, and preventing crushing of proppant pillars during the fracture closure.
