Premier Quartz
This
tool is a very short ‘quartz’ style downhole pressure and temperature
recorder. The tool features a single housing with the leak path
protected by a silver coated metal O-ring providing a metal / metal
seal, secondary metal / metal and double O-ring seal. The
electronics are protected by being housed in a sealed internal chamber
which has been evacuated and filled with argon. These measures render
the tool especially suitable for long duration jobs in difficult
conditions and wells with highly corrosive fluids and gasses.
FEATURES:
•
Windows software package produces screen plots,
printouts and
export files at the well site.
•
The Quartzdyne sensor generates low
drift, high accuracy and excellent
resolution data in
all conditions.
• Metal-to-metal seals eliminate leaks in
hostile wells.
APPLICATIONS:
• Production testing in HPHT wells.
• Well testing in HPHT wells.
BENEFITS:
• Records high quality pressure and
temperature data.
•
The Premier Quartz is supplied with
new electronics for every data
gathering campaign which
means
better
reliability. |

Extreme Quartz
This
new 200 degree C memory gauge brings together the Hybridised Quartzdyne
transducer and Omega’s own high temperature electronics, to produce a
reliable memory gauge for the most hostile of well conditions.The
tool will record very high quality pressure and temperature data in
wells where the pressure is 20,000 psi and the temperature reaches 200
degrees C.
FEATURES:
•
Windows software package produces screen plots, printouts
and export files at the well site.
• The Quartzdyne sensor generates low drift, high
accuracy
and excellent
resolution data
in all conditions.
• Metal-to-metal seals eliminate leaks in
hostile wells.
• Detachable batteries for easy
replacement.
APPLICATIONS:
• Production testing in HPHT wells.
• Well testing in HPHT wells.
BENEFITS:
•
The Quartzdyne sensor generates low drift, high
accuracy
and excellent
resolution data in all
conditions.
• Metal-to-metal seals eliminate leaks in
hostilewe lls.
• Omega’s user friendly ‘Run-It-Yourself’ package
can
reduce the POB.
•
The Extreme Quartz is supplied with
new
electronics for every data
gathering campaign which
means
better
reliability. |

Sentinel Tool
The
Omega Sentinel is an extremely rugged downhole pressure and temperature
recorder designed to be run as part of any wireline string. This fully
automatic gauge requires no operator input to start or stop the tool
recording to memory.The tools continuously monitor the pressure and
temperature, then starts to record to memory when the pre-set
thresholds are exceeded. Each survey is stored in a separate file in
the tools 1,000,000 data set memory. The data is recorded against real
time sp each survey is easily identified.
FEATURES:
• 1,000,000 data set memory gives a full history
of your
wireline operations.
• The tool is continuously powered with a real
time clock and is full automatic.
•
Windows software package produces screen plots,
printouts and export files at the well site.
• The extremely low power consumption means that
the
batteries will last
longer, as a result the tool can stay
in the field
for up
to one year.
• The AA size battery falls below the
IATA dangerous good threshold.
APPLICATIONS:
• Any bottom hole pressure and
temperature survey.
• The tool can be run with Perforating
Guns. |
 |
Micro Automatic Gauge
This
tool requires no operator input to acquire data. Omega supply the tool
in monitor mode which means the sensor is checking for pressure and
temperature changes every two minutes.
FEATURES:
•
Windows software package produces screen plots, printouts
& export files at the
well site.
• Any Omega downhole gauge can be used as
surface
recorder.
• The tool is totally automatic so requires no
operator input to record data.
• All data is stored with real time values so data
identification is simple.
• 1,000,000 sets of data so a one
second sample rate gives 11.5 days
of data.
• Overall length, with a six month battery pack,
is just 10.5” making wireline
rig-up easier.
• Innovate electronics dramatically
reduce battery power consumption.
• The AA size battery falls below the
IATA dangerous good threshold.
APPLICATIONS:
• Production surveys.
• Gradient surveys.
• Coil Tubing gauge carrier.
• Gravel pack data gathering.
• In an Omega gauge carrier or in the
Omega
• Set Down Weight Recorder.
• Well testing.
• Surface pressure recorder.
