Paper presented at the SPE/AAPG/SEG Unconventional Resources Technology Conference, June 13–15, 2023
Paper Number: URTEC-3860563-MS
... 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...

... deep-water reservoirs around the world. Introduction Mixed siliciclastic-carbonate mudstone unconventional reservoirs contain complex sub-well-log-scale heterogeneity in mineralogical composition due to depositional process variability (Lazar et al., 2015; Comerio et al., 2020, Kvale et al., 2020...

... reservoir contributions to producing unconventional wells. Failure to account for geologic variability, analytical limits, and source and reservoir signatures can lead to misleading and costly allocations. Further, lack of recognition of what causes chemical variation beyond simply source facies leads...

The quadrant style classification scheme is a unique rock typing tool, particularly for low stiffness zones where texture variability will dictate pressure support versus permeability hindrance. The resulting geologic framework offers...

Although PCA methods have been shown to explain high percentages in variabilities when robust elemental data are available, it mainly depends on the assumption of linear relationships. We introduce a new algorithm that outperforms our earlier results on the same dataset. Uniform...
