Memory Production Logging System
|
In memory production logging the production logging tools are run on non conducting wireline (slickline) or on coiled tubing. Power is supplied by a lithium battery at the top of the string. Instead of data being sent up the line the telemetry is decoded and data is stored in a memory tool according to a pre-programmed sample rate. Simultaneously depth and line speed data is recorded at surface in memory. After the tools are recovered from the well the two sets of data are merged with output files in ASCII format of depth, line speed and tool responses. These ASCII files are read into log plotting software and after depth correlating plotted as production logs.
