... Abstract This paper builds on Klenner et al. 2018 , which utilized machine learning to understand well-to-well communication ("Frac hits") or fracture-driven interaction (FDI) during hydraulic fracturing operations. This paper introduces an infrastructure that enahances the process for real...

... Ghanizadeh et al. (2016) described a method to estimate unpropped fracture permeability and propped fracture permeability as a function of stress using core plugs. The measurement sequence involves first measuring matrix permeability ( k m ) on intact core plugs under stress (and as a function...

... parts of the Montney. In most parts of the Montney reservoirs, porosity is about 3 to 12 percent and permeability is in the order of 100 nano darcy. Such low porosity and permeability of the Montney makes hydraulic fracturing stimulation necessary in order to produce from the reservoir economically...

... Abstract Reducing fracture/well spacing and increasing hydraulic fracture stimulation treatment size are popular strategies for increasing hydrocarbon recovery from multi-fractured horizontal wells (MFHWs). However, these strategies can also increase the chance of fracture interference, which...

... rock volume and divert the fracture energy away from the depleted zones. This study investigates pre-loading and re-fracking of parent wells as potential Pressure Sink Mitigation (PSM) techniques to minimize fracture asymmetry in child wells. The impact of these techniques on possible production uplift...

... Abstract Analytical rate transient analysis (RTA) techniques are widely adopted for analyzing production data obtained from hydraulically fractured horizontal wells in tight or shale reservoirs. However, for a detailed characterization of the uncertain distributions of those complex...

Abstract An experimental procedure was developed to incorporate the mechanisms of Gas-Cycling Enhanced Oil Recovery (GCEOR) phase behavior, IFT change, swelling, viscosity reduction and residual-liquid shrinkage in the presence of porous media possessing propped hydraulic fractures and matrix...

...) of the Duvernay Formation to investigate the effects of kerogen maturity and mineralogy on pore morphology and wettability of shales. We investigated the effects of organic-pore connectivity and fractures on wettability of the EOW plugs. By using CT scan images, we divided EOW plugs into highly-fractured (HF...

As depicted in Fig.3 , the case study entails hydraulic fracturing of 4 stacked Multi-Frac Horizontal Wells (MFHWs), hereafter referred to as A, B, C, and D, targeting the lower Montney in British Columbia. The treatment starts with zipper-frac of A and C wells and is followed by zipper-frac...

Both types of inter-well communication tests have become common among the operators in tight and shale reservoirs. However...

... Abstract A new stage-by-stage analytical framework to identify and control high water influx stages in horizontal wells was successfully used in a multi-layer reservoir in Southeast Saskatchewan, Canada. The wells of interest were drilled in the Midale formation and hydraulically fractured...

... Abstract The purpose of this paper is to quantify the importance of lateral heterogeneity of permeability and porosity when modeling horizontal, multi-fractured tight unconventional wells exhibiting layer-wise fluid heterogeneity. Fluid and petrophysical properties are taken from the Eagle Ford...

... Abstract Cyclic gas injection in hydraulically-fractured wells has been successfully applied as an enhanced oil recovery (EOR) method in tight unconventional basins such as the Permian and Eagle Ford. However, displacement processes (continuous gas, solvent or water injection) such as those...
