Solvent-free consolidation system controls proppant flowback
Solvent-free consolidation system controls proppant flowback

flowback after fracturing or installation of liners can increase productivity and reduce operat-ing costs to turn marginally commercial fields into profitable assets. Wells are often shut in or abandoned when they become uneconomical to produce at lowered production rates. In many cases, production of hydrocarbons becomes restricted when producing

A method of treating ,flowback fluid, comprising: introducing the ,flowback fluid, into a first stage vertical separator to produce a first gas stream, a liquid stream, and a solids stream; passing the first gas stream from the first stage vertical separator to a sales line; passing the liquid stream from the first stage vertical separator to a second stage horizontal separator with the pressure ...

This causes the invaded hydraulic-,fracturing fluid, to be trapped in small pores within the matrix and accumulate near the hydraulic fracture. The profile of liquid saturation in the figure shows the overall blockage caused by both aqueous and condensate phases that leads to a significant reduction in the gas relative permeability near the fracture (Fig. 1b).

1/2/2020, · Flowback after hydraulic fracturing consistently shows a significantly poor load recovery of the fracturing fluid. The unrecovered fluid creates a blockage at the matrix-fracture interface in the reservoir, which hinders the optimum hydrocarbon production.

Hydraulic Fracturing Flowback water: Following the fracturing process, a portion of the fracking fluid returns to the surface for about two weeks. Produced Water: More water may be produced along with oil and gas after the flowback period is over and well is in production.

The effects of fracturing fluid retention on gas flow in the fracture face can be as important as fracture conductivity when designing a treatment. It is possible to have a conductive fracture with good half-length in the desired productive zone and still not realize economic or optimum gas production if phase trapping and/or relative permeability effects are restricting gas flow.

23/11/2014, · As fresh oil has flowed, so have new jobs. Hydraulic ,fracturing, – or “fracking,” as it is often referred to – is the process of drilling deep beneath the earth’s surface to crack, or fracture, rock formations to access oil and natural gas deposits. The process is not new, but advancements in technology spurred a recent boom and vaulted the United States to No. 1 status among the ...

As natural gas production has shifted further from deep prolific gas reservoirs to shale gas, several questions are being addressed regarding ,fracturing, technologies and the fate of chemical additives. A less investigated issue is the unexpected increase in produced hydrogen sulfide (H2S) from hot shale gas reservoirs. Understanding the source of H2S in shale reservoirs and managing low-levels ...
