This file contains unprocessed drilling data tests on Sierra White Granite (SWG) using two new PDC bits. The tests were conducted at Sandia National Laboratories (SNL) in the Hard Rock Drilling Facility (HRDF). The collected data includes ROP data at rotational speeds of 80, 120, ...
The main objective of the developed software is to reduce the cost per foot during drilling, in other words, optimize the drilling operational parameters in achieving optimum ROP while avoiding critical operational parameters due to either low ROP, drillstring vibration, accelerat...
These reports review Fervo Energy's construction of a commercial enhanced geothermal system (EGS). Fervo has qualified full functionality of the system through production testing at commercially relevant operating conditions. The project site is located in a nearfield setting ad...
Polycrystalline diamond compact (PDC) bits are routinely used in the oil and gas industry for drilling medium to hard rock but have not been adopted for geothermal drilling, largely due to past reliability issues and higher purchase costs. The Sandia Geothermal Research Departmen...
Operational performance requirements are needed to support development of specifications for downhole motor power sections to be used for drilling hard rock during geothermal wellbore construction. Theoretical torque specifications are derived based upon a widely-accepted rock-re...
Final Technical Report for the GLADE Geothermal Drilling project in the DJ Basin of Colorado. The Geothermal Limitless Approach to Drilling Efficiencies (GLADE) project was undertaken to evaluate whether advanced oil and gas drilling practices could be adapted to improve geotherma...
Lessons Learned document for the GLADE Geothermal Drilling project in the DJ Basin, Colorado. The Geothermal Limitless Approach to Drilling Efficiencies (GLADE) project was undertaken to evaluate whether advanced oil and gas drilling practices could be adapted to improve geotherm...
Pre-Drill drilling prognosis for the GLADE Project wells, GLADE East and GLADE West, in the DJ Basin Colorado. The Geothermal Limitless Approach to Drilling Efficiencies (GLADE) project was undertaken to evaluate whether advanced oil and gas drilling practices could be adapted to ...
Files include daily mud reports for GLADE East and GLADE West wells in the DJ Basin, Colorado. Reports include daily mud data summaries for each well while drilling. The Mud Reports summarize mud composition and volumes each day throughout the project.
The Geothermal Limitless A...
Files include daily operational and drilling reports for GLADE East and GLADE West wells in the DJ Basin of Colorado. Reports include drilling summaries for work done and progress made daily for each well. There is a companion Final Drilling Report that summarizes some of the data...
The Geothermal Limitless Approach to Drilling Efficiencies (GLADE) project was undertaken in Denver-Julesburg (DJ) Basin Colorado to evaluate whether advanced oil and gas drilling practices could be adapted to improve geothermal well construction in deep, hot, hard-rock environmen...
Bottom hole assembly (BHA) designs were assessed in field trials for their ability to achieve critical low inclination requirements, while simultaneously enabling high drill rates. Because angle has historically been controlled by reducing weight on bit (WOB), these are often com...
Files include Well Log information and raw data files for both GLADE East and GLADE West geothermal wells in the DJ Basin, Colorado. Data can be viewed with a PDF file viewer or log viewer capable of reading .LAS files. Log types included are Cement Bond Logs (CBL's), Mud Logs, a ...
Permit Plans for GLADE East and GLADE West wells in the DJ Basin, Colorado. Files contain pre-drill permit information on the siting and anti-collision analysis for the wells. Wellbore trajectories are evaluated to position the wells within and around existing wellbores. Files inc...
Raw EDR (Electronic Drilling Recorder) data for GLADE East and GLADE West wells in the DJ Basin, Colorado. This data was recorded during drilling of both wells and is presented as two zip files. The zip files contain data from different portions of the wells, surface, intermediate...
Two ZIP files include Bottom Hole Assembly (BHA) summary data and results for both GLADE East and GLADE West wells in the DJ Basin, Colorado. Files contain bit photos, BHA assembly info, and where available post-run reports or logs for each run in each well. Data is separated int...
A fundamental issue in microhole drilling is that delivering high weight-on-bit (WOB), high torque rotational horsepower to a conventional drill bit does not scale down to the hole sizes necessary to realize the envisioned cost savings An optimization algorithm called a golden sec...
This submission contains photographs of rock core collected from EGS Collab Experiment 2 (and 3) boreholes. Cores were generally photographed in about 1-foot sections using Nikon D3300 DSLR cameras from two angles about 90 degrees apart, wet and dry. Core photos are provided here ...
This package includes data and models that support hydraulic fracture stimulation and fluid circulation experiments in the Sanford Underground Research Facility (SURF). A paper by Schwering et al. (2020) describes the deterministic basis for developing a "common" discrete fracture...
The objective of advanced drilling and logging technologies is to promote ways and means to reduce the cost of geothermal drilling through an integrated effort which involves developing an understanding of geothermal drilling and logging needs, elucidating best practices, and fost...
This submission has two shapefiles and a tiff image. The weights of evidence analysis was applied to data representing heat of the earth and fracture permeability using training sites around the Southwest; this is shown in the tiff image. A shapefile of surface temperature anomali...
The McGee Mountain geothermal area was selected to test early-stage shallow temperature survey techniques and drill two slim holes to test the resource. Geothermal Technical Partners, Inc. was able to complete only a small portion of the project before lack of funding prevented f...
Drilling results from the microhole project at the Sandia High Operating Temperature test facility. The project is seeking to help reduce the cost of exploration and monitoring of geothermal wells and formations by drilling smaller holes. The tests were part of a control algorith...
The files in this submission describes the results of a series of stress measurement and hydraulic fracturing experiments conducted at the Sanford Underground Research Facility (SURF) in Lead, SD. This report describes the accomplishments of the kISMET (permeability (k) and Induce...
Understanding the initiation and arrest of earthquakes is one of the long-standing challenges of seismology. Here we report on direct observations of borehole displacement by a meter-sized shear rupture induced by pressurization of metamorphic rock at 1.5 km depth. We observed the...
