1/2/2021, · The ,fracturing fluid, entering the shale reservoir leads to the reduction of the gas permeability of shale to a certain extent, especially for the imbibition time longer than the inflection point of the resistivity change in our work, and that way the ,fracturing fluid, should be ,flowback, earlier. So the shut-in time should be controlled reasonably.

The key point is that the flowback fluid differs from the initial fracking fluid that was used during injection, with respect of composition. The majority of the volume of sand and proppants stays trapped within the pores of the formation, while the chemical additives react due to intense injection conditions, such as high temperature, resulting in reaction products.

The work defined the relationships between gas well ,productivity, and stress sensitivity, formation angle, and WGR. The results indicate that deliverability increases with an increase in formation angle, and growth rate hits its limit at an angle of 40 deg. Due to the influence of formation angle, ,fluid, gravity leads to production pressure differences in gas wells.
