Project Overview
The Olene Gap Geothermal Energy and Data Center Project is located in Rural Klamath County, Oregon, approximately 9–10 miles east of Klamath Falls. The project area provides space for geothermal generation, wellfield facilities, electrical infrastructure and potential co-located data-center development.
The current strategy is phased, beginning with approximately 10 (2X5) MW of geothermal generation and expanding to 20 (4X5) MW and potentially more, subject to final resource confirmation, engineering, permitting, financing and commercial arrangements.
There are Pacific Power's 69 KV and 12 KV power lines on this private land for easy access to power.
Geology, wells and resource assessment
The following project images are drawn from the Olene Gap technical record. Figure numbers below are assigned specifically for this website.

Understanding P90 and P10
P90 is the more conservative, higher-confidence case: in standard exceedance terminology, there is about a 90% probability that the actual resource measure will equal or exceed the P90 estimate. P10 is the larger, more optimistic case: there is about a 10% probability that the actual resource measure will equal or exceed the P10 estimate. The two cases illustrate a probabilistic range; they are not guarantees of plant output.
P50 is the median possibility. As per one reservoir engineering report it is 12 MW and as per another reservoir engineering report it is 22 MW.
Existing well information
OG-1 was drilled to approximately 3,775 feet and recorded temperatures of approximately 250°F. Testing and evaluation indicated strong permeability and injectivity characteristics, supporting the case for further wellfield development.
Additional production and injection drilling, testing and engineering will be required as the project proceeds toward commercial operation.
Why the existing work matters
The Olene Gap project is not beginning with a desktop concept. Existing drilling, test data, resource studies and project-development work can be reviewed to determine precisely what additional work is needed for the next phase.
