Over 100,000 Pressure values from Quartz sensor can be stored at 24 bit accuracy in the standard tool; this capacity can be increased if required. The data files generated can be analyzed with standard commercially available packages.
The Production Logging tools can be run with a Memory Section. This allows this type of log to be used on SLICKLINE or COILED TUBING and also for TFL applications. Up to six tools can be used simultaneously in addition to a Casing Collar Locator and a Pressure Gauge. Approximately 30,000 complete sets of readings can be taken before any memory expansion is required. When Production Logging with a memory string, depth is recorded on a separate instrument at the surface. File merging software is supplied to allow depth referenced logs to be presented in standard API format.
To Program and download the tool, a computer is used. The computer "talks" to the memory section using software which contains a Profile Editor for selection of tools and sample rates for up to 256 program steps. Once a program is completed, it is loaded into the tool and verified, after which applying battery power will start it running. Other functions contained within the software include tool testing, data conversion, merging, etc.
A computer based Depth/Time recorder adds the ability to relate the recorded data to depth. This device also includes the interface to program and download the tools. Standard printers can be used to output Plots and Logs after processing by commonly available software packages, e.g. PLATO, PETCOM, LISTOOLS, etc.
