... Abstract This work presents a novel framework to quantify the variability in hydraulic fracture geometry in a multi-cluster multi-stage hydraulic fracturing treatment well using stage-by-stage Instantaneous Shut-in Pressure (ISIP) analysis. The fundamental Sneddon’s equation is used to develop...

... by increasing trends in instantaneous shut-in pressure (ISIP). Rate per perforation was found to be a statistically significant predictor of near wellbore connectivity. Far-field diverter was also used to enhance nearfield connectivity and achieve better uniformity. Introduction Hydraulic fracturing...

.... The stress interpretation results from the DFIT cycles demonstrate that fracture reopening pressure generally provides a reliable estimate of the minimum principal stress (S 3 ). ISIP consistently provides a relatively higher estimate of S 3 and can be used as an upper limit for constraining S 3 . Fracture...

... indicates stress shadowing effects among neighbor stages. The uncertainties are estimated using the statistical bootstrapping method. In addition, the stress inversion results were compared with ISIP (Instantaneous Shut-In Pressure) data and b-values and show some level of consistency. Introduction Vaca...

... difference simulator using each of the three petrophysical inputs. Scalars for the models were calibrated to offset DFIT data. The resulting models were compared to determine the optimal model. Pre-stimulation instantaneous shut in pressures (ISIP) was evaluated in the horizontal well for each stage. High...

... stimulation stages. Water hammer simulation also suggests an accurate method to estimate instantaneous bottom-hole shut-in pressure (ISIP). This ISIP estimation for multi-stage treatments clearly shows the impact of the inter-stage stress shadow effect when applied to multi-stage fracture diagnosis...

..., the instantaneous shut-in pressures (ISIP's) measured during each hydraulic fracturing stage depict significant variations in the estimated S hmin magnitude along both WDFD wells (Figure 1, Figures 2b and 3b). The estimated S hmin values generally scatter between the lower bound set by the frictional...

... because of its low permeability and the commingled completions used to produce the Spraberry/Dean/Wolfcamp intervals. The first technique uses a Pad ISIP methodology to obtain calculated pore pressure values across all 10 completion stages in each vertical well using 10 bbl injection tests...
