Utah FORGE 3-2417: Pulsed Interference Tests at Wells 16A(78)-32 and 16B(78)-32 - September 2024

Description

This archive contains data and a report from Pulse Interference Tests (PITs), which were conducted on September 4, 2024, immediately following a 30-day recirculation test at the Utah FORGE site. Injection and backflow were induced in well 16A(78)-32 while pressures were measured in wells 16A(78)-32 and 16B(78)-32 (hereafter referred to as 16A and 16B) during a single day of testing. During the tests, 16B was shut in so that variations in formation pressure could be measured. The PITs included three pressure pulse periods of 20, 40, and 120 minutes, repeated four times each. The recorded periodic hydraulic responses in 16B were minuscule but were resolved through filtering processes at the known frequencies of pulses. The ability to extract hydraulic signals from noise using time-series analysis is a significant practical advantage of periodic PITs, as small injection volumes can be used.
