GHT-Gas Holdup Tool
Measures the gas void fraction in the wellbore around the tool
The Gas Holdup Tool (GHT04) has been designed to measure the gas void fraction in the wellbore around the tool.
To achieve the measurement, a 3 milicurie cobalt source is mounted in the bottom of the tool to emit gamma rays, which are then detected by a scintillation type detector for counting. The GHT tool provides an excellent measurement of the gas fraction in wellbores.
