The advent of modern horizontal drilling and hydraulic fracturing helps make the Bakken oil production economic. upstream oil & gas drainage drillstem testing drillstem/well...

... Abstract The objectives of this paper are: (1) to present a workflow for X-ray micro Computed Tomography (micro-CT) applied to field cores, (2) to show examples of high-resolution X-ray scans of sections of the slant core from the Hydraulic Fracturing Testing Site 2 project (HFTS2...

... Abstract Well interference directly impacts well spacing optimization and well economics, thus it has received significant attention. Observed in many unconventional reservoirs, well interference is mainly attributed to connection of hydraulic fractures. Few studies have compared the hydraulic...

... wells were drilled around a single Middle Bakken producer to measure wetted and conductive fracture geometries. Trajectories of the two monitor wells, one in the Middle Bakken and one directly below the producer in the Three Forks, were strategically designed to intersect hydraulic fractures at varying...

... oil reservoir is modeled with a pair of parallel horizontal wells in the reservoir producing at equal rates. Varying well spacing, perforation cluster spacing, and BHP generate a total of 11 combinations of depletion scenarios. The hydraulic fractures are characterized by the local grid refinement...

... Abstract The Montney play is currently the most prolific unconventional resource in the Western Canadian Sedimentary Basin. It is exploited through hydraulic fracturing of multiple benches and is prone to induced seismicity - a potential hazard and nuisance to operations and residents...

... Abstract Well spacing and hydraulic fracture design optimization are among the most important challenges confronting companies operating in unconventional reservoirs. Field trials are time consuming and expensive. Reservoir simulation and/or rate transient analysis can help guide development...

... Abstract This paper demonstrates how geochemical production allocations can be used to calibrate reservoir simulation models and improve the optimization of well spacing and hydraulic fracture design in unconventional assets. Geochemical analyses provide quantitative assessments of flow...

... Abstract A 3D numerical model is presented to analyze the gas flow behavior in hydraulically fractured horizontal wells in anisotropic heterogeneous naturally fractured reservoirs with triple porosity (organic and inorganic matrix, and a fracture network). This model generalizes the models...

... Abstract Hydraulic fracturing is extensively used to stimulate unconventional oil and gas and geothermal reservoirs. The fluid is pumped into a selected section of the wellbore to create and extend a fracture(s) into the formation. The applied pressure in the fracture(s) re-distributes...
