... Assessment Partnership’s (NRAP) Integrated Assessment Model NRAP-Open-IAM, we assessed the risk of brine and CO 2 leakage along nearby, hypothetical cemented wellbores and through the caprock layer above the storage reservoir. The following components of NRAP-Open-IAM were used to setup the model...

... Stratigraphic sequences are sometimes thin, rarely horizontal and juxtaposed due to faulting. Wellbore trajectories in such strata may not lie along principal stress direction. Perforations for hydraulic fracturing may also be inclined to the principal stress direction. Fundamental understanding...

.... Preliminary results suggest that internal shale barriers mitigate dispersion and deter migration into the caprock, cushion gas volumes significantly impact brine production, elevated gas saturations are preserved near the wellbore utilizing lateral placement of perforations, and associated brine production...

Our primary zone of interest is the horizontal section of the wellbore located in the Codell Formation. We identified a low-velocity section of the horizontal well through data analysis. The low...

... of strike-slip event is often observed independent of fault activation. These events occur in the completion interval, strike parallel to the hydraulic fracture growth and trend towards pressurized offsetting wellbores. The mechanism of these events is possibly due to a stress rotation and shear on existing...

... fluids associated with hydraulic fracturing of unconventional reservoirs. We compute the CSEM signature of conductive injected fluids and determine the effects of the position of the injection site along a lateral wellbore and its conductivity, while also considering the conductivity of the source...

... multiple receivers and one cross-dipole source is lowered into a well. As the tool descends into the well, the cross-dipole source excites high frequency (kHz) waves into the geologic formation adjacent to the wellbore. When these waves hit a scatter, they reflect back towards the well, where the downhole...

In addition, such models depend on strict assumptions for using the measurements...
