Abstract: A fracturing fluid is injected under a high pressure into a well drilled in a formation to create a hydraulic fracture. Then a suspension of the hydraulic fracturing fluid mixed with proppant particles is injected into the well and the created hydraulic fracture, the suspension having a consistency coefficient greater than 0.1 Pa sn at any flow index n and a yield stress higher than 5 Pa. Then, an overflush fluid having a consistency coefficient lower than 0.01 Pa·sn is injected into the well.

Abstract: A method for preventing formation of a slug flow regime of a gas-liquid mixture in a non-linear wellbore or a pipeline comprises determining at least one most probable place of fluid slugs development in the wellbore or the pipeline by mathematical simulation based on expected values of the gas-liquid mixture flow and known geometry of the wellbore or the pipeline and mounting a device, in the determined place of fluid slug development, that converts the stratified gas-liquid mixture flow into a dispersed flow.
