Utah FORGE: Post Hydraulic Fracturing Circulation Testing Fiber Optics Report - August, 2024

This report documents the post hydraulic fracturing extended circulation test between wells 16A and 16B during August 2024. In 16B, fiber optic measurements of RFS DSS and DTS were primarily used to detect and map thermal inflow anomalies, as detected by thermally driven strain changes and thermal changes from DTS. The report provides a first pass integration of SLB Production Logging Tool (PLT) results with fiber optic results to look for correlations between the two different types of data. The report also takes a close look at the Fiber Optic derived cross well strain signatures created during the 16A frac, as detected at 16B producer well and correlates those Fracture Driven Interactions with the Circulation Flow Test results.
