Multi-Stage Hydraulic Fracturing in TNK-BP

Advantages: Disadvantages: Technological simplicity; Good communication with the formation (“well – formation”); Well completion cost Uncontrollable “blind” frac: – impossibility to define the fracture initiation point; – necessity of re-perforation (on the tubing); – fissuring + uncontrollable frac fluid losses;

The ,fluid,, which now has a slightly higher pressure than when it entered the first stage, enters the next impeller and diffuser stage to repeat the ,process,. The ,fluid, passes through all stages of the pump, incrementally gaining pressure in each stage until it achieves a total developed head, or designated discharge pressure, and has sufficient energy to travel to the surface of the well.

The ,advantages, of this fracture ,fluid, are: large reservoir volumes stimulated, better fracture containment and damage reduction generated by gels. Its ,disadvantages, are: excessive use of water, narrower fracture widths that other fluids and a poor capacity to carry the proppant toward the interior of the fracture due to its low viscosity.

Synthetic ,flowback, water was obtained by reacting the synthetic ,fracturing fluid, with 25 g/L shale at 80 ℃ and 83 bar for 24 h simulating downhole conditions encountered in natural gas reservoirs. The variation in these conditions across different gas formations can be large,and its impact on polyacrylamide degradation was investigated previously.

Hydraulic ,fracturing, is used to increase the permeability of shale gas formations and involves pumping large vols. of fluids into these formations. A portion of the frac ,fluid, remains in the formation after the ,fracturing process, is complete, which could potentially contribute to deleterious microbially induced processes in natural gas wells.

Disadvantages: • Treatment must be sufficient to allow reuse/ recycle for subsequent fracking purposes. • Treatment may be difficult, expensive or not practical. • Treated water must be stored until it can be reused. • Fracking companies must be able to adjust their process to use treated water which may be expensive and incur operational risks.

Commonly, large volumes of water-based ,fracturing, fluids are injected into the reservoir during the ,fracturing process,. However, there is a large difference between the volume of slick water injected and ,flowback,, which means a lot of slick water remains trapped in the reservoir and will react with the shale matrix [ 14 – 16 ].
