When bottom-hole flow pressure equaled formation pressure, gas well ,production, was not 0 × 10 4 m 3 /d, the angle was large, and gas well ,production, was greater. Deliverability and stress sensitivity hold a linear relationship: the stronger the stress sensitivity, the lower the deliverability of the gas well, with the stress sensitivity index from 0 to 0.06 MPa −1 and the deliverability ...

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 ...

The well type is horizontal well. The main reasons for the poor ,production, effect of Well Z202-H1 are as follows: Reservoir pores are not developed; continuous thickness of thin reservoir; insufficient ,fracturing, treatment; low ,flowback, rate, large water ,production, and wellbore ,fluid, accumulation.

4.4. Mitigating reservoir damage by retained ,fracturing fluid, and environmental pollution by ,flowback fluid,. The retained conventional ,fracturing fluid, forms a zone with high water saturation in the microfractures or the matrix pore throats near the fractures, which affects the gas transmission and damages the gas deliverability of the gas reservoirs.

The misalignment fracture width of sample 1 is mainly concentrated in the range of 1.019‐2.719 mm, whereas the fracture width of sample 2 is mainly concentrated in the range of 1.921‐5.766 mm. The misalignment fracture of sample 2 provides a more convenient passage for fluids to flow therein. Figure 4.

Recent studies have focused on how wastewater disposal wells have caused dramatic increases in eastern US earthquakes. We focused instead on less common cases where hydraulic ,fracturing, alone has caused earthquakes and found seismicity separated into two depth zones: a shallow zone on younger faults, with more small-magnitude earthquakes than expected, and a deeper zone on older …
