... decreases with time, during which the decline rate is large at the initial stage, and decreases with time till reaching a plateau. When the slickwater is used, the daily production of 70— 200 m 3 /d in conventional horizontal wells can reduce sand production. When the guar is used, the critical flow rate...

... experiment. With the increase of reaction time, the number of dissolution pores increased and the pore size enlarged, which caused the enhancement in porosity and permeability (up to one order of magnitude) and the decrement of tensile strength (up to 47%). Compared with slickwater fracturing, supercritical...

... conducted on the layered Chang-7 tight sandstones and the influences of multiple factors were studied. Experimental results showed that the complexity of HFs created by Sc-CO 2 fracturing could be significantly enhanced compared with that of slickwater fracturing, but only improved to a limited extent...

... ABSTRACT: Accurating estimation of fracturing friction is critical to reservoir stimulation, and drag reduction performance is also the most important technical indicator of slickwater. Fracturing friction consists of three parts: wellbore friction, perforating hole friction and fracture...

.... Fracture cell was designed in certain ways to capture the impact of fracture orientation by 45°, 60°, and 90° on settling velocity. Results showed HVFR provided better proppant transport capability than regular FRs used in slickwater. Proppant settling velocity using HVFR was decreased by 80%. Results...

... ABSTRACT: Slickwater hydraulic fracturing is becoming a major completion and stimulation tool nowadays for enhanced oil and gas production. Friction reducers (“FR’s”) are essential to reduce pressure loss for the high pumping rates used, and their value is well known. However, what is less...
