The
Electronic Multi-Shot is
Designed to meet the demands of the borehole survey market, the
EMS
probe provides high accuracy definitive
survey information, before you case the well - in time to make any
directional course corrections.
It
provides a
cost effective alternative to photomechanical
borehole survey tools, eliminating the need for film developing, yet
fits in Peewee size running gear. The EMS
also provides
extended operational performance over
conventional electronic multishot products on the market. For high
temperature applications, the EMS
can be run in a standard PeeWee size thermal shield and pressure
case with an OD of 1.75”.
The EMS
can be readily connected to any Windows (95/98, 2000,
XP, ME) compatible
computer. Using the DMS Drillog TM survey and graphics software,
survey output formats can be customised by the user. These can
include a variety of parameters and plots including time, depth,
inclination, azimuth, gravity highside, magnitude and dip of earth's
magnetic field, probe temperature and raw data output for each
sensor. The EMS can also be used in
conjunction with a handheld palmtop style computer when a PC is not
required or optional LCD readout on probe.
