Geothermal wells: CCTV Surveys and Geologging

Geophysical logging and CCTV surveys can provide vital data and checks for the construction and development of geothermal wells.

• Measurement of fluid temperatures
• Identification of flow zones
• Monitoring of water quality
• Evaluation of formations
• Checks on borehole construction
• Monitoring the effects of well development
• Assists in the design of wells
