... Abstract This study provides the first direct observations of horizontal bedding plane slippage detected using cross-well low-frequency distributed acoustic sensing (LFDAS) during hydraulic fracturing stimulation in the Sichuan Basin, China. Traditional completion designs assume vertical...

... Abstract Distributed Strain Sensing (DSS) is frequently used to capture hydraulic fracture propagation and geometry in unconventional reservoirs and Enhanced Geothermal Systems (EGS). DSS fibers are sensitive to strain variations induced by dilation and shear deformation of hydraulic fractures...

... Abstract The combination of hydraulic fracturing and horizontal wells has been very well established. Initially deployed in moderate quality conventional style reservoirs ( Owens et al. , 1992 ), ( Abou-Sayed et al. , 1995 ) and ( Cipolla et al. , 2000 ). Then, more recently, and even more...

... Recently, multi-stage hydraulic fracturing is being implemented in hot geothermal reservoirs both in enhanced geothermal systems (EGS) and superhot reservoirs such as the Utah FORGE and Newberry, respectively. Hydraulic fracturing in these fields poses distinct challenges to design...

... to legacy data acquired from the asset. After thoroughly evaluating the acquired data, a complete pad is history-matched using an integrated hydraulic fracturing and reservoir simulation workflow. The calibrated model is then used for a sensitivity study, which is further enhanced through machine learning...

... a vertical well with a single planar hydraulic fracture extending to the boundary of the reservoir ( Fig. 2 , left). The well is assumed to be isolated and not in communication with offset wells. The single-porosity reservoir is assumed to be homogeneous and isotropic, and the producing fluid...

... into production from unconventional oil, condensate and gas reservoirs. Stress-dependent Pore compressibility Considerations NaSh simulation model considers a finite size reservoir block, with a well and hydraulic fractures. The fractures are introduced into the model as discrete features. Hence, dual...

..., requiring the implementation of a stimulation service or the placement of a small hydraulic fracture to be able to bypass the damaged zone, restore the injectivity, balance the economics and comply with the government requirements. In other cases, despite properly planning the placement of the disposal...

... of completion styles from small hybrid to large slickwater treatments. Production performance is analyzed along with acquired data and field tests run by previous Operators. After a complete reservoir characterization (both petrophysics and geomechanics), an integrated numerical model for hydraulic fracturing...

... to detect many micoseismic events being at close proximity to the hydraulic fracture. However, only hodogram details of the signals on the three-component geophones are able to constrain the depth of the microseismic event. Compared to geophones deployed in a vertical well, the depth accuracy is relatively...

... Abstract A combination of hydraulic fracturing and horizontal wells is now being used to tap geothermal energy from naturally fractured reservoirs. Fully grid-based numerical models are currently used to simulate heat recovery from enhanced geothermal systems (EGS). Such models require a fine...

... electromagnetic (EM) surveys for the past six years to monitor hydraulic-fracture behavior at the Devine Fracture Pilot Site (DFPS). The sub-horizontal orientation of a shallow hydraulic fracture at the DFPS provides uniform access to the fracture area for interrogation and data collection. Ahmadian et al. (2023...

... nominally planar growth orthogonal to the wellbore for the two cased and perforated zones – favoring intersection with the soon-to-be-drilled production well. These treatments superficially seem mundane. However, they successfully demonstrated the viability of hydraulic fracture creation in a cased well...

... and pressure at the mouth (entrance) of hydraulic fractures. Because both pipe and perforation friction are proportional to flow rate squared, standard step-down tests that rely on the steady pressure response at a set of injection rates cannot uniquely determine pipe and perforation friction. We introduce...

... In the period from 1990 through 1995, STIM-LAB Inc. conducted a wide-ranging study into various aspects of hydraulic fracturing treatments of coal reservoirs. The final report ( STIM-LAB Inc., 1995 )contains the outcomes and recommendations of a number of novel experiments, ranging from...

... as well as hydraulic fractures induced by the parent well completions. Following coring operations, a full log suite including formation image log (FMI) was acquired to further characterize reservoir properties. This also provided an opportunity to ground-truth the more commonly used measurement...

... that was conducted to optimize multistage hydraulic fracturing design in the presence of natural fractures of various density in the Clair field. The production uplift of hydraulic fracturing in conventional reservoirs is well understood. However, the presence of natural fractures adds an unconventional twist...

... Abstract In collaboration with the Advanced Energy Consortium, our team has previously demonstrated that the placement of electrically active proppants (EAPs) in a hydraulic fracture surveyed by electromagnetic (EM) methods can enhance the imaging of the stimulated reservoir volumes during...
