The logging system is manufactured by Century Geophysical
Corporation located in Tulsa, Oklahoma. This system
digitizes all the sensor measurements downhole,
which minimizes interference from varying wireline
cable lengths and other factors that may affect
the data.
The interface between the logging tools and the
host computer is via a specially developed Multi
Protocol Tool Card which fits into any standard
ISA slot in the host computer. Visual Compu-Log
software to run the log acquisition, log display
and processing is installed on the host computer
and operates under the Windows 98 environment.
Black and White printouts of the acquired logs are
available at the well site upon completion of the
log acquisition; colour logs are also available
after log processing.
The entire logging system is housed within a commercial
van for rapid deployment to the well site. Aztec’s
logging tools are capable of recording multiple
parameters in a single logging run minimizing rig
standby time.
All tools acquire a Natural Gamma log for easy depth
correlation between separate logging runs. All measurements
are calibrated and can be recorded in engineering
units or counts per second.

Notes on the 9057 tool:
1. Electric logs must be run in non-cased, fluid filled
boreholes
2. After processing, the x - y inclination and azimuth
logs provide a detailed report on the verticality and
direction of the borehole.
3. A porosity log is also acquired for a given formation
matrix.
