The Effect of Long-term Shut-in Periods on Fracture ...
The Effect of Long-term Shut-in Periods on Fracture ...

Hydraulic ,fracturing, can significantly increase the completion time of a well. It is common to flow the ,treatment fluid, back after each stage to recover the ,fluid,. Concerns over potential fracture conductivity damage, due to ,treatment, shut-in for an extended period of time, have dictated this practice.

After hydraulic fracturing, the pumping pressure is decreased, and fluid in the formation returns to the surface through the well casing (GWPC & ALL Consulting, 2009; Gregory et al ., 2011 ). This water is referred to as ‘flowback’, and the period of flowback is variable but commonly lasts 2 weeks.

However, most flowback requires some kind of chemical or physical treatment step to make it suitable for fracturing operations. As such, treatment technologies are usually deployed to meet one or more of three main goals: control of particulate matter, removal of deleterious components and bacterial disinfection. Solids in flowback

Shale Frac Sequential Flowback Analyses and Reuse Implications
Shale Frac Sequential Flowback Analyses and Reuse Implications

Load recovery following fracturing operations is a key aspect of any water reuse program since the load recovery volumes may vary across operating locations and the amount of water that can be recycled is dependent upon the final water chemistry. In many cases, significant dilution of flowback water with fresh water is applied to new completions.

Flowback, water can be anywhere from 15 to 40 percent of the volume of ,fluid, that is injected (i.e., forced down a well), and flows back up to the surface over a period of 3−4 weeks after ,fracturing,. More than half of the ,fracturing fluid, remains in the formation. The ,flowback, water …

Flowback, is the portion of the injected ,fracturing fluid, that flows back to the surface, along with oil, gas, and brine, when the well is produced. An estimated 90% of ,flowback, in the United States is disposed of into deep EPA-licensed Class II disposal wells , with the remaining less than 10% reused, evaporated, used for irrigation, or discharged to surface streams under an NPDES permit.

Hydraulic ,fracturing fluid, (HFF) additives are used to enhance oil and gas extraction from unconventional shale formations. Several kilometers downhole, these organic chemicals are exposed to temperatures up to 200 °C, pressures above 10 MPa, high salinities, and a pH range from 5–8. Despite this, very little is known about the fate of HFF additives under these extreme conditions.
