Hydraulic fracturing in the United States - Wikipedia

Hydraulic fracturing in the United States, began in 1949. According to the Department of Energy (DOE), by 2013 at least two million oil and gas wells in the US had been hydraulically fractured, and that of new wells being drilled, up to 95% are hydraulically fractured.The output from these wells makes up 43% of the oil production and 67% of the natural gas production in the United States.

In this on-the-fly method, a stream of liquid epoxy resin is injected directly into the proppant-laden, gelled fracturing fluid. Advantages of this process include, reduced, proppant flowback,, reduced, bulk handling of resin proppant flowback,, reduced, bulk handling of resin coated proppant, and in many cases, increased fracture flow capacity of the treated wells.

Method to Predict Proppant flowback in Fractured Gas well ...

1/1/2012, · Introduction, Fractured gas well, is more easily to experience proppant flowback than, fractured, oil well during the production stage because, fluid, rate is higher in gas well. some gas well occurs proppant flowback phenomenon in the production process after fracturing of XinJiang oilfield and ChangQing oilfield.

Proper fluid and proppant placement are crucial to successful propped fracture stimulation. Numerous completion diagnostic technologies are available to characterize the placement of the treatment. Until recently, characterization of fracturing fluid cleanup could only be simulated in the laboratory and anecdotally monitored in the field.
