Application of Low Amplitude Seismic Emission Analysis to Evaluation of Hydrothermal Fractures Underlying the Western Flank of Newberry Volcano, Oregon

Abstract

Davenport Resources engaged Sigma3 to deploy an array of seismometers in cased shallow wells in the vicinity of deep exploration well 46-16, located on the western flank of Newberry Volcano, Deschutes County, Oregon. Monitoring lasted for seven days. Well 46-16, with a shut-in well head pressure of 600 psi, was opened once a day for three consecutive days, to allow fluid to flow from fractures into the well bore. The well was then shut in to allow pressure build-up. The results of the this test of the application of Low Amplitude Seismic Emission Analysis to detect hydrothermal fluid flow within fractures is reported.
