Abstract
Accurate wellbore measurement was made possible with the use of electronic Temperature-Pressure-Spinner (TPS) equipment in PNOC-EDC geothermal wells.
Combined waterloss, injectivity and pressure fall-off data are derived in a single completion survey. Various wellbore phenomena such as downilows,upflows and gas feeds are detected through the logs.
Downhole measurement of the non-condensible gas content of production fluids is also made possible at any depth above the flashpoint.
Stand-alone spinner logs are also used regularly for measurement of well injection capacities.
Examples of various applications are presented.
