Southwest Alaska Regional Geothermal Energy Project-Implementation of a Demonstration Enhanced Geothermal System Project in Naknek, Alaska
CX(s) Applied: B3.1
Location(s): Naknek, Alaska
Office(s): Energy Efficiency and Renewable Energy, Golden Field Office
Naknek Electric Association, Inc. (NEA) would demonstrate the potential geothermal resource of the existing G-1 well by performing logging and flow tests of the well. This project was previously analyzed in Department of Energy/Environmental Assessment-1759 Southwest Alaska Regional Geothermal Energy Project near Naknek, Alaska. However, an additional task (1.2 logging and flow tests) was added to the project, therefore another National Environmental Policy Act review was needed. Data gathered from the logging and flow tests of G-1 would be used by NEA to characterize the geothermal resource. This analysis is for Task 1.2 only. Task 1.2) Conduct Post-drilling Logging and Analysis of Previously Collected Geophysical Logging Data - Conduct a series of post-drilling logging runs and flow tests (if warranted) on G-1. Evaluate the suite of logs collected in G-1 during drilling in order to construct a seismic velocity model, estimate rock strength, and determine the magnitude of the vertical stress. If required, run additional geophysical logs to determine fracture characterization, understand formation properties, and deduce the orientation of the stress field.
