... Abstract A general assumption in unconventional development is that horizontal wells in close vertical proximity tend to interfere with each other, causing the ultimate recovery of each well to be diminished to the extent that their stimulated rock volume (SRV) overlaps. However, recent...

... Basin. The obtained uncertainty is propagated further to report probabilistic production forecast and assess the well-spacing impact on oil recovery both for individual wells and for the whole field. We built a 1-by-2-mile reservoir-simulation model for the two wells of interest. We hypothesized three...

... approaches and lead to insights about predicting and engineering flow regime changes. To assess the impact of completion technology on flow regime changes, we first quantified metrics for production data for 16,000 Midland tight oil well production data, including Estimated Ultimate Recovery (EUR), time...

... Abstract Carbon capture and storage in depleted shale gas reservoirs offer an opportunity to utilize CO 2 for enhanced gas recovery while providing access to fossil fuels. To evaluate CO 2 sequestration coupled with enhanced gas recovery (CO 2 -EGR-CCUS), we have developed a model...

This paper outlines the implementation of three multi-disciplinary methods and best practices that when used...

... is recovered and transported to the laboratory. Due to the change in pressure and temperature throughout the recovery process as well as the associated subsequent on-site handling procedures, a significant amount of oil / water and especially gas will be lost or significantly altered. Pressurized coring...

... Abstract Formation compressibility (pore volume strain per unit change in reservoir pressure) is an important rock property that can directly impact drive energy and recovery in conventional reservoir settings but is invariably minimized/ignored when simulating unconventional resource rocks...

These include undesirable asymmetrical fracture propagation toward the primary well, adverse fracture/fluid interactions with the depleted fracture network, and under-stimulated reservoir volume around the infill well. These interactions reduce the recovery potential...

The overall purpose of a horizontal well is to effectively distribute the wellbore drawdown into the reservoir over a larger area than a vertical well completion, thereby improving the recovery and economics. After the well has been completed...

.... The sample was monitored for 300 s at 1% oscillation strain followed by 1000% oscillation strain to shear the sample for 30 s. At t = 0 min, 1% oscillation strain was applied for 300 s to allow the sample to recover. Percent recovery was calculated by comparing values of the storage modulus/loss modulus...

Success is dependent on many variables, several of which include well spacing, completion design, and mechanical stratigraphy. Optimizing development is contingent upon understanding how these variables interact...
