Complex Econonomic Optimization, Part 1

For Office Hours this month, we had a presentation from ResFrac Director of User Success, Dave Ratcliff. He presented a Complex Economic Optimization workflow where he explains how to vary stage length, cluster count, and well spacing while keeping the perforation friction drop constant to maximize NPV/Section. This is part 1 of a 2-part series, we will continue the discussion in an upcoming Office Hours.

Modeling CO2 injection and long-term storage using ResFrac

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.

Refracturing, Automated History Matching and Automated Economic Optimization

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.
