Project Title Advanced Seismic data Analysis Program (The “Hot Pot Project”)
Project Type / Topic 1 Recovery Act: Geothermal Technologies Program
Project Type / Topic 2 Validation of Innovative Exploration Technologies
Project Description The proposed exploration surveys, drilling programs, data analysis and report generation will require 18 months to complete. It is anticipated that the resource confirmation drilling program will be successful in intersecting structural targets predicted by the 2.5-D advanced seismic analysis and model construction, effectively validating use of this innovative technology as a means to reduce drilling risk through improved well targeting. Oski expects that temporary field jobs will be created during the drilling stage and that long-term direct and indirect jobs would be created once this geothermal resource is proven and a geothermal plant is designed, financed and built.
State Nevada
Objectives Improve geothermal well target selection and reduce drilling risk through the application of an innovative and advanced analytical method for interpreting seismic data to locate deep geothermal structures.

Targets / Milestones The proposed project involves the application of advanced seismic data analytical techniques to generate a 2.5-D structural image of the project area. Recent data analysis of seismic surveys performed in geothermal systems has utilized the current accepted technique of first-arrival velocity optimization followed by pre-stack depth migration (Honjas et al., 1997, Pullammanappallil et al., 2001, Unruh et al., 2001). However, this technique is constrained by accurate velocity information below depths of 3,000 feet and approximates deeper information by ‘stacking’ velocities along an assumed gradient. The Hot Pot project proposes to improve upon this method by using the innovative analytical techniques of combined Coherency-First Arrival data processing and Full Waveform Inversion velocity model derivation to construct a 2.5-D model of the geologic structure at depth. Higher resolution images can be produced with a 3-D seismic survey, but this requires a very dense grid of tightly constrained seismic lines which is very expensive to run. It is expected that results equivalent to a 3-D model can be obtained at a cost approaching that of a standard 2-D model with the proposed 2.5-D technique.

Impacts If successful, this should provide higher-quality seismic reflection images and more accurate depth control on imaged structures at depths typically targeted in geothermal fields.
