Flowback,, the flowing of gas, formation ,fluid,, and hydraulic ,fracturing fluid, up the wells to the surface, took place over 10–14 December, after which both wells were in production. A reduced emission completion (REC) was performed; gas produced during this time was captured using portable equipment brought on site that separates the gas from the liquids so that the gas can be retained as a ...

Investigation of the Factors Influencing the Flowback ...

The results show that the ,flowback, ratio is inversely proportional to the clay content of the ,shale,. A high salinity ,fracturing fluid, or a surfactant solution can increase the ,flowback, ratio. In addition, the injection pressure is proportional to the ,flowback, ratio, while the matrix permeability and the ,flowback, ratio have an inverse relationship.

Removal of organics from shale gas fracturing flowback ...

Shale, gas ,fracturing flowback fluid, contains various degradation difficulty organic compounds after hydraulic ,fracturing,. A hybrid treatment method was developed for treating ,flowback, and produced water (FPW) using pre-treatment (NaClO) followed by the expanded granular sludge bed (EGSB) and moving bed biofilm reactor (MBBR).

Flowback, water is water that returns to the surface within 14 days of the initial ,fracturing, event. ,Flowback, data made available by the ,Shale, Network were collected using geographic information systems (GIS). ,Flowback, sample analytes of interest were DRO and GRO compounds. These samples came from gas ,shale fracturing, wells located within the

Petropedia - What is Frac Flowback? - Definition from ...

At present, ,frac flowback, is very much associated with the production of natural gas or ,shale, gas through ,shale, rocks using horizontal drilling and hydraulic ,fracturing, process. It is recovered from the well at the surface when the ,fluid, is used to hydraulically fracture the ,shale, formations.

Effect of the Fluid–Shale Interaction on Salinity ...

Hydraulic ,fracturing, has been widely implemented to enhance hydrocarbon production from ,shale, reservoirs. However, one of the main challenges during hydraulic ,fracturing, is to understand what factor(s) trigger high salinity of ,flowback, water, which sometimes can be up to 300 000 mg/L. While several mechanisms have been proposed to explain the controlling factor behind the high salinity of ...

A tremendous amount of water-based ,fracturing fluid, with ancillary chemicals is injected into the ,shale, reservoirs for hydraulic ,fracturing,, nearly half of which is retained within the ,shale, matrix. The fate of the retained ,fracturing fluid, is raising some environmental and technical concerns.
