... Abstract The Greater Permian Basin includes both conventional and unconventional oil production. While Permian's conventional oil production (via primary, secondary, and enhanced oil recovery) has been very successful over the last half a century, the average primary oil production from its...

Primary drainage and one cycle of CO 2 huff-n-puff were conducted sequentially. Oil recovery was obtained through core mass measurement, produced liquid mass...

... Abstract CO2 Huff and Puff provides dual benefit of sequestration and enhanced oil recovery in unconventional oil fields. We present a novel hybrid model optimization workflow for huff-n-puff operations. The resulting high-dimensional optimization problem with 5n+2 (for ‘n’ huff-n-puff stages...

... parameters - one of the most important being the impact of well interference on the estimated ultimate recovery (EUR) per well, when more than one well is drilled per drilling spacing unit (DSU). This paper outlines the implementation of three multi-disciplinary methods and best practices that when used...

... 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...

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.

... 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...

... 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...

... 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...

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...
