LDEO-BRG developed a multipurpose data acquisition
system (3rd Party DAS) installed in the Downhole Measurements
Lab (DHML) to interface with a wide variety of logging
tools and support equipment. This system offers numerous
features including a standard computer platform from which
to launch acquisition software, several power supplies,
and a work space in the acquisition area devoted to third-party
equipment. Currently, the system is based on unique modular
software for data telemetry, equipment triggering and switching
for a variety of downhole devices. Each module has been
written for a specific piece of equipment and can be run
from any PC with the proper hardware installed.
The system currently utilizes the Windows XP operating
system. Recent enhancements to the third-party tool included
the design of a cablehead crossover that allows third-party
tools to connected to the Schlumberger cablehead via an
inexpensive, modified off-the-shelf connector. BRG maintains
two identical DAS systems.
