Lamont Test Well Overview

Two holes were drilled into the wide ranging rocks underlying the Lamont Campus. Both holes penetrate the diabase sill while the deep hole pushes thought the bottom of the sill into the sand-shale sequence beneath the sill. Both holes will remain uncased, however the shallow hole will contain a high pressure vessel and associated apparatus which will become a high pressure testing facility for logging tools and other long downhole devices.


  • Field testing equipment (baseline logs are available)

  • Pressure testing equipment to 10,000 psi

  • Cross-well hydrologic investigations

  • Tracer test

  • Pump and slug tests

  • Packer tests

  • Fracture analysis

For information regarding the geology of the test hole or the logging
operations that have been carried out, please see the Lamont page in the
Research and Projects section.
