.... Abstract Shale and tight formations are characterized by extraordinarily low permeability (micro- to nano-Darcy) and existence of natural fractures at various scales. Horizontal drilling with multi-stage hydraulic fracturing has enabled commercial oil and gas production from those unconventional resources...

... recovery (EOR) processes. Currently, to achieve economic levels of production from these reservoirs, long horizontal wells with extensive hydraulic fracturing are required. However, the recovery factors are low, often less than 10% (Hoffman 2018), meaning large quantities of oil remain. Given the current...

... is close to the producing end) to a field case with a flow-regime signature attributed to a near-hydraulic fracture permeability enhancement, some similarities and differences are observed. This study demonstrates that the effects of rock heterogeneity on RTA results can be effectively studied...

... has a thickness of 20 m. This thickness is the height of the parallelogram representing the fault. The greater rectangular solid is used to exert the uniform background stress field to eliminate the boundary effect on the simulation. A parent well with three hydraulic fractures is placed 75 m away...

.... Abstract As has been demonstrated recently, flowback data from multi-fractured horizontal wells (MFHWs) can be analyzed to provide early estimates of reservoir and hydraulic fracture properties. However, MFHWs in close proximity (e.g., drilled from the same well pad) can experience inter-well communication...

... Abstract This study observed hydraulic fracture propagation, arrest, and closure in permeable rocks. The experiment was conducted on a Molasse sandstone block in a true triaxial state of stress. The study monitored fracture opening at the wellbore and fluid pressure measurements to understand...

... Abstract Imaging the reopening of a sub-horizontal Hydraulic Fracture (HF) propped with Electrically Active Proppants (EAPs) during pressure injections has been demonstrated by conducting controlled source electromagnetic surveys at UT-Austin's Devine Fracture Pilot Site (DFPS). To detect HF...

...) and document the journey from first discovery to field trials. ADD is a process where un-cemented, open hole laterals are drilled contemporaneously between offset "standard" wells, using the ADD wells to "harvest" productivity from offset well hydraulic fractures. A "standard" well or "frac well" refers...

... Abstract To maximize shale volatile oil field liquids production, an integrated study was conducted by quantifying the relative contributions of fluid properties, drawdown rates and hydraulic fracturing designs. The first part of this study includes analyzing production data from dozens...

...) is the phenomenon due to the depletion effects from parent wells affecting the fracture growth from child wells during the stimulation process. The child well hydraulic fractures preferentially propagate towards the lower pressured depleted regions. As a result of FDI, parent wells often experience high water cut...

The hydraulic fracture distribution for the studied stage was derived using a 1D geomechanical model. The hydraulic fractures from the three perforated intervals considered in this study were...

... Abstract Casing deformation occurs during hydraulic fracturing of unconventional plays, which often compromises wellbore integrity, compromises operations, and leads to a decrease in productivity and economics. In the Austin Chalk Formation, South Texas, casing deformation was commonly...

Each well has an arbitrary number of equally spaced hydraulic fractures of identical properties. Those properties can vary from...

... horizontal wells that were drilled and produced from 2011 through 2022, with two (2) of them being recently refractured in 2022. The calibration effort consisted of matching the daily rates (oil, gas, and water) and bottomhole pressure values of all the wells, during the hydraulic fracturing, flow back...
