Description:
The SS2100
Pressure/Temperature gauge combines an external fast response
platinum wire resistive temperature device (RTD) with Spartek
Systems’ proprietary high resolution sapphire pressure
sensor.
Pressure and temperature are fundamental measurements that are
required for both reservoir characterization and wellbore diagnostics.
A standard pressure gauge will normally have an internal temperature
sensor to automatically compensate the pressure transducer for
temperature effects. This sensor will typically provide accurate
temperature data, however, the temperature response time is
too slow for most applications. As seen in the graph below,
the external RTD has a response time ten times faster than the
internal temperature sensor found on most gauges. This is primarily
due to the amount of mass surrounding the internal sensor.
Utilizing
a proprietary sapphire pressure sensor, a fast response external
RTD, and the latest in low power data acquisition technology,
the SS2100 is
ideally suited for both long term monitoring, and wellbore diagnostics
applications (cement tops, tubing leaks, channeling, and gas
lift valves). The low power electronics and large memory capacity
allow the user to collect up to 666,666 data sets (pressure,
internal temperature, and external temperature) with a single
C cell battery. Depending on sample rates, this could represent
surveys from 3 months to 1 year. This performance has been achieved
without sacrificing sampling speed or resolution.
Spartek
Systems provides all the necessary tools and software to use
this technology for both stationary monitoring applications
and continuous depth based logging.
