Acoustic monitoring of hydraulic stimulation in granites
… its high levels of heat and recoverable energy. Hydraulic fracture stimulation of low permeability EGS reservoir rock is widely employed to develop this resource and is generally required to make unconventional resources an economically viable resource. Significant challenges for EGS technology …

Structure Segmentation and Transfer Faults in the Marcellus Shale, Clearfield County, Pennsylvania: Implications for Gas Recovery Efficiency and Risk Assessment Using 3D Seismic Attribute Analysis
… an attempt to intersect fractures for effective hydraulic stimulation. If the fractures are contained within the shale, then hydraulic fracturing can enhance permeability by further breaking the already weakened rock. However, natural fractures can affect hydraulic stimulations by absorbing …

Time-lapse seismic AVAz in the Stocker Field
Organic rich Murdock reservoirs require hydraulic stimulation to be economically productive. Zones of high fracture density are desired due to the increase in permeability they would have. Thus, fracture characterization is an essential part of production planning in unconventional reservoirs. …

Imaging a Hydraulically Fractured Bakken Shale Reservoir Using 4D-Tomography and Reverse VSP Techniques with Perforation Shot Sources
… but also due to variabilities in the reservoir’ stimulation. Seismic images may be inconclusive in identifying areas where hydraulic fractures have penetrated and microseismic events can have uncertainties in their location and description. I propose the use of perforation shots to map regions …

Mechanical stratigraphy of the Vaca Muerta Formation, Neuquén Basin, Argentina
… are likely candidates for reactivation during hydraulic stimulation based on a stability assessment. The middle of the interval is suitably brittle, organic rich, and has now been documented to contain multiple natural fractures. Although this conclusion was reached independently, it is …

Structural and stratigraphic controls on fracture distribution within sand bodies of the Upper Iles and Lower Williams Fork formations, Mamm Creek and Divide Creek fields, Piceance Basin, Colorado
… natural fractures or induced fractures from hydraulic stimulation. Natural fractures have been documented to significantly enhance reservoir permeability. This thesis examines the stratigraphic and structural controls on fracture distribution within the Mamm Creek field through the use of …

Stress prediction, fracture detection, and multiple attribute analysis of seismic attributes in a Barnett Shale gas reservoir, Fort Worth Basin, Texas
… reservoir's ability to conduct hydrocarbons when hydraulically stimulated. The study area is a natural gas producing area of the Barnett Shale in the Fort Worth Basin of North Texas. To facilitate this project, EOG provided RCP with electric well logs, 3D P-wave seismic, microseismic, and …

Geomechanical Reservoir Model Calibration and Uncertainty Assessment from Microseismic Data
Hydraulic stimulation of low permeability rocks in unconventional reservoirs has been observed to trigger microearthquakes (MEQs). Triggering of the MEQ events has been linked to the pore pressure, temperature, and in-situ stress variations which result in crack initiation. The resulting clouds of …

Challenges of geophysical processes and interpretation of an unconventional play: a case study from Wattenberg field, Denver-Julesburg Basin, Colorado, The
… observed microseismic activity trends from hydraulic treatments. Identification of these correlations would improve the petroleum system characterization of the western flank of the basin’s syncline. However, the unforeseen presence of amplitude artifacts from acquisition footprint coverage …

Simulating and diagnosing three-dimensional multistage hydraulic fracturing with the generalized finite element method
Hydraulic fracturing is the process in which a fracture propagates through the injection of pressurized fluid in its cavity. This technique allows one to considerably enlarge the accessible reservoir volume by the injection of fluid along with the isolated segments of the wellbore into the …
