This analysis underscores the importance of incorporating initial gas production data into the input variables...

The sequence initiates with reservoir levels in bottomset facies and evolves to clinoform geometries that prograde from southeast to northwest (Vittore et al. 2020).

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...

... data of the child well was evaluated against a nearby legacy producer. Compared to a base geometric design, the stage count was reduced by 8 (19%), total entry points and cluster efficiency remained the same, and the average stage Shmin variability was reduced by over 80%. Based on modeling results...

... Abstract Variability is embedded in unconventional plays both on a regional and local scale. This inherent variability – when present in production wells – can be managed when the average ultimate recovery for of the development wells remains above the commercial threshold. During the early...

... 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...

... is therefore defined by the S+A fraction while resins and asphaltenes are considered not producible. Geochemical data indicate that petroleum stored in the pores of the shales have variable SARA composition, ranging from 50% S+A in low thermal maturity portions of the basin, to 97% S+A in higher maturity areas...

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...
