The DeviCore BBT is the
latest core orientation
innovation
from Devico. The DeviCore BBT
represents an integration
ofthe patent pending
Brilliant Blue™ technology
and other proprietary
Devico technologies. The
DeviCore BBT employs the same
Devidip system probe
technology which has proven
to be an industry leader in
reliability for more than 10
years as a part of the
Devidrill,
combining electronic core
orientation integration with
brand new ergonomic running
gear. The kit includes two
DeviCore BBT probes and a
core barrel extension and is
ready to be assembled on the
drilling equipment on site.
The probes also has a valve
system in front securing
that pump-in time isnot
affected.

|
|
|
|
DeviCore BBT comes equipped
with the IP67 rated Nomad
PDA system and DeviSoft.Mobile
software. The operation
follows a clear step-by step procedure,
and one probe can be started
and downloaded while the
other is down in the hole.
DeviCore BBT uses three
high-accuracy
accelerometers, it measures
inclination, orientation,
gravity vector, temperature
and battery status, and
offers quality control on
the results. Communication
between DeviCore BBT and the
PDA is done wirelessly via
Brilliant Blue Technology.
USING DEVICO’S CCO SYSTEM
OFFERS THE FOLLOWING
ADVANTAGES:
No interruption of the
drilling cycle, i.e.
Cost effective
Regular readings
Accurate orientations and
inclination
Effective in a broad range
of ground types and core
breaks
Provides high orientation
accuracy from 0ºto
+/-88° dip
Digital data recorded for
use in analyses at a later
time

If you know how to run your
inner tube, you know how to
run your DeviFlex. It is
THAT easy. DeviFlex is a
non-magnetic electronic
multishot for surveying
inside casings and drill
strings by simply using the
wire line system. Magnetic
disturbances will not
influence the tool at all
and it is supposed to be
simple to use. Just pump the
tool into the hole and pull
it out in given intervals.
No adjustments are necessary
The DeviFlex tool consists
of two independent measuring
systems. Three aaccelerometers
and four strain gauges are
used to calculate
inclination and change in
azimuth. In addition, the
DeviFlex records and stores
gravity vector,
temperature, and battery
capacity.
|
|
|
|
The DeviFlex fits casings
and drill strings from
B-size and up to P-size. You
need one instrument and a
set of sleeves with various
wheel sizes to adjust for
different hole ddimensions.
The tool has been proven to
work in horizontal as well as
vertical holes.
The DeviFlex communicates
with a PDA, and the results
can be viewed on the PDA
screen in field once the
data is downloaded from the
tool. The data can
thereafter be further
processed in DeviSoft,
analyzed, plotted andreported
to the client.
