... in over the past years. When run before fracturing in an open hole, it highlights formation heterogeneities and helps selection of the best zones to be fracked. If run after fracturing in a cased hole, this new type of log acquisition can be considered as a PLT proxy for identifying the producing clusters...

... of heterogeneity of imbibition in shale samples. The dynamic processes of water imbibition in the 1-inch (25.4 mm) core sample were explicitly demonstrated, and the imbibition along the matrix and imbibition through microfractures is distinguished through neutron radiography image analysis. The causes of observed...

... Abstract The tight carbonate Units within the Permo-Triassic Khuff Formation in the Middle East are considered the most prolific unconventional gas reservoir in the world. The Khuff reservoirs in Saudi Arabia are known for their complex vertical and lateral heterogeneity at the mesoscopic...

.... However, consistent conclusions regarding surfactant performance have not been reached, partially due to heterogeneity in unconventional reservoirs. An additional problem is upscaling the results of fluid loss studies from the laboratory to the field. For accurate prediction of fracturing fluid loss...

The impacts of geologic heterogeneity, completion design with multiple zippered wells, offset and infill wells on the size and shape of a dynamically changing SRV were studied. Additional cases were designed to investigate the impacts of (1) prior depletion...

The scale and degree of heterogeneity in unconventional reservoirs provides additional challenges for. Wireline logs provide measurement of physical phenomena at reservoir conditions...

... fracturing in unconventional reservoirs usually rely on simplified, log-based models. In such models, vertical heterogeneities are upscaled to a few, averaged facies with homogeneous stiffness, stress, strength, toughness and natural fracture properties. In reality, however, unconventional reservoirs often...
