In this case areas of high proppant concentration, i.e., above 7.3 Kg/m 2 (1.5 lb/ft 2) are zones prone to ,flowback,. As the reservoir ,fluid, (or ,fracturing fluid, during cleanup) moves through the bed of proppant, it can, with enough velocity, pick up the upper layer of unconsolidated proppant, move it to the wellbore or settle it in some fracture cavities.

26/4/2017, · Hydraulic ,fracturing, is the process of pumping a ,fluid, into a wellbore at an injection ,rate, that is too great for the formation to accept in a radial flow pattern. As the resistance to flow in the formation increases, the pressure in the wellbore increases to a value that exceeds the breakdown pressure of the formation open to the wellbore.

It involves pumping ,fluid, into a wellbore to create enough pressure to fracture the hydrocarbon-bearing rock layer. The ,fracturing, takes place at the start of the wellbore's life cycle. The injected ,fluid, is often water, and it usually contains various chemical additives and a proppant, like sand, to keep the fractures open so oil and gas can flow to the well.

One of the significant issues associated with fracking in shale is that massive amount ,of fracturing fluid, (~5–50%) is retained in the formation after the fracking process [10,11]. For example, Ge [9] and Penny et al. [12] reported that only around 5% of the water is recovered the ,fracturing, processes in shale while Nicot et al. [13] found less than 20%.

Then, the volume of secondary fracture system can be estimated from the volume ,of fracturing fluid, injected into reservoir layer. Assuming the matrix block is divided into plats by secondary fracture (Fig. 2 ), the porosity of connected natural fractures is 100% and the system compressibility of secondary ,fracturing, networks is homogeneous, ω and λ are defined as (Warren and Root 1963 ; Wang 2015 ):
