What’s New: HFTC, the Parent/Child Industry Study, HFTS2, Supercritical Geothermal, DFIT, and Automated History Matching
This post reviews some of the more interesting things happening at ResFrac right now: HFTC paper with Apache on Calibrating models with offset fiber, parent/child well industry study, HFTS2 project, engineering geothermal systems, DFIT’s and automated history matching.
Introducing ResFrac’s Sensitivity Analysis Tools
ResFrac’s sensitivity analysis tools help operators to create, run and interpret batches of simulations that vary systematically, enabling convenient and reliable work flows to test ideas and optimize economic performance.
The ResFrac Parent/Child Industry Study has Kicked Off!
ResFrac’s Industry Study will be studying the interactions between parent wells and child wells (infill wells) to identify optimizations that improve economic performance.
Why Deep Closed-Loop Geothermal Is Guaranteed To Fail
Deep closed-loop geothermal relies on heat conduction to bring energy to the wellbore. Conduction through rock is slow: a fundamental problem that will prevent the concept from ever being economically viable.
Integrated Reservoir Modeling Supports a Culture of Continuous Improvement
The ResFrac mission is to accelerate the process of continuous improvement. We simulate the entire well lifecycle in a single integrated simulation, help operators to synthesize information, make changes, and continue to improve.
The Value of Subsurface Modeling
ResFrac’s physics-based subsurface modeling helps oil and gas operators to identify inconsistent data, explain complex phenomena, and optimize decision making.
Theoretical and Empirical Problems with the Holistic Permeability Correlation for DFIT Interpretation
In this post, I focus on a particular correlation that is sometimes used in the industry to estimate permeability from a shale DFIT: the ‘holistic permeability correlation.’ I show that this correlation can greatly overestimate permeability. When applied to optimize frac design, well spacing, and cluster spacing, overestimated permeability leads to significant loss of economic value.
