Project Title Feasibility and Design for a High-Temperature Downhole Tool
Project Type / Topic 1 Laboratory Call for Submission of Applications for Research, Development and Analysis of Geothermal Technologies
Project Type / Topic 2 High-Temperature Downhole Tools

Project Description Although the oil and gas industry have been regularly using logging tools for measuring the characterization of formations while searching for hydrocarbons, these tools can only operate up to 150–175oC. The maximum operating temperature can be increased up to 260oC when thermal shielding is used. In this proposal, Oak Ridge National Laboratory will investigate the feasibility of developing components for enabling operation at higher temperatures, up to 400oC for use in geothermal wells. The need to operate at higher temperatures for geothermal wells is the main challenge, and the primary objectives of this proposal are to measure and characterize the effects of the downhole environment on the scintillation properties of the candidate crystals.
State Tennessee
Objectives Perform both feasibility and design studies for a high-temperature downhole tool that can measure the porosity, lithology (mineral composition of formation), and density profile of geothermal wells as a function of depth.

Targets / Milestones - Evaluate and test the commercially available scintillators.


- Evaluate high performance scintillators that are not commercially available.
- Investigate the availability of photosensors capable of meeting the stated environmental specifications via an evaluation of prior related work on what would be considered highly specialized photosensors and environmental testing of commercially available photosensors having specifications that most closely match the stated environmental specifications.
