Utah FORGE Modeling and Simulation Forum #2

"Hydraulic Fracture Stimulation Patterns in the FORGE Reservoir Using Multiple Stochastic DFN Realizations and Variable Stress Conditions" presented by Aleta Finnila (Golder)

May 20 at 11 am MDT

The presentation includes a summary of the current FORGE reference DFN and the sensitivity work performed to find average and end-member DFN realizations for hydraulic stimulation of the new well 16A(78)-32. There is a discussion of how the DFN can be used by other modelers and what type of filters should be used on the DFN in order to extract the best set of fractures for a particular simulation goal.The presentation includes a summary of the current FORGE reference DFN and the sensitivity work performed to find average and end-member DFN realizations for hydraulic stimulation of the new well 16A(78)-32.

This is the second forum of the series and is intended to have an open format to present modeling and simulation, both completed and planned, as well as activities being conducted by the Utah FORGE Team. This webinar has been recorded and is now available for viewing.

UPDATE: Audio recording has been fixed. Enjoy the full version.
