Exploration Basis
A vertical seismic profiling survey was conducted to gain a better understanding of the geology and structure of Neal Hot Springs and the surrounding areas. This study was conducted by students and faculty in geophysics field camps from the Colorado School of Mines, Boise State University, and Imperial College London.
 
Notes
Three vertical seismic profiles (VSPs) were taken in three different wells. A 60 kg accelerated weight drop and Vibroseis machine was used as the seismic source. Two receiver arrays were used, one was a linear geophone array on the surface and the other was a sonde located down hole. The surface geophones were spaced at 1 m intervals and only measured the up-going wave field. The downhole sonde measured both the up-going and down-going wave fields. Geoids were used to digitize analogue signals. There were data quality issues during this survey due to interference from well casings and a layer of mudstone which obstructed deep measurements. The deepest recordings were 184 m.
