For this month’s Office Hours, we had a presentation from ResFrac Senior Reservoir and Completions Engineer, Ankush Singh, on modeling CO2 injection and long-term storage using ResFrac. The true injection capacity of a CO 2 storage site should be calculated in terms of how much fluid can be injected economically, while minimizing the risks such as caprock failure and induced seismicity. We will discuss some of the fully coupled 3DResFrac simulations we performed to better understand the changes in the subsurface resulting from CO2 injection. The simulations demonstrate the importance of utilizing a fully integrated 3D hydraulic fracture, geomechanics and compositional fluid flow simulator to understand the subsurface risks and optimize CO 2 injection.

For this Office Hours, Garrett Fowler reviews his recent blog post, “Automated history matching to fracture geometries as measured by Volume to First Response (VFR): A Tutorial.”

For Office Hours this month, ResFrac Director of User Success, Dave Ratcliff, gave a review of his 2022 HFTC paper with Devon, Modeling of Parent-Child Well Interactions.

For Office Hours this month, we had a presentation from ResFrac Senior Reservoir and Completions Engineer, Rohan Irvin, on optimizing well spacing and completion design using simulation models calibrated to the Hydraulic Fracture Test Site 2 (HFTS-2) dataset.

This Office Hours presentation from Mark McClure on refracturing, automated history matching, and automated economic optimization covers a ResFrac case study using a public ‘refrac’ dataset on which we perform an automated history match to the original and ‘post-refrac’ dataset. Then, we perform an automated economic optimization on job size for the refrac design.

For Office Hours this month, we had a presentation from Mark McClure entitled, “Direct Validation of DFIT Interpretations from In-Situ Strain Measurements,” reviewing a presentation he gave on April 11, 2022, at Saga Wisdom’s Sökkvabekkr conference in Austin, TX.

For this Office Hours, we continued the topic introduced by Professor Mark Zoback on the recent updates to the North American Stress Map with a presentation by ResFrac’s Ankush Singh on predicting stress profiles from log and lab data using the Viscoelastic Stress Relaxation (VSR) concept.
