Paper presented at the SPE Canada Unconventional Resources Conference, September 28–October 2, 2020
Paper Number: SPE-199967-MS
... 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...

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...

... included petrophysical and geomechanical properties along with a 2D discrete natural-fracture network representing the distribution of natural fractures in the reservoir. Hydraulic fractures in parent wells were modeled using original stress settings from the 3D-MEM. Then, a dynamic model was constructed...

Paper Number: SPE-199987-MS
... 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...
