Geothermal Fast Tool

Description

Geothermal Fast Tool

The Geothermal Fast Telemetry (GFT) is a high temperature logging tool that will allow you to work continuously for up to 4 hours at 350ºC or up to 6 hours at 300ºC. This unit measures and records: wellbore temperature, pressure, flow, gamma ray, and collar locator using a high end electronic system protected by a flask housing. Different sizes of flowmeters are available based on your wellbore design. GFT runs on Warrior System (SDS), and on Memory mode.
