Electronic Replacement for Mercury Maximum reading thermometers

Page last modified
April 11 2024

In the past, Maximum reading mercury thermometers were placed in logging cable heads to get a uniform, independent downhole temperature measurement. With the banning of mercury, AccSensum have developed the T-1000 thermometer (patented) allowing temperature vs time logs for the entire run duration.

Pros & Limitations
1
Up to 3 independent temperature measurements per run
1
Installation does not interfere in any way with wireline tool string or telemetry
1
With multiple runs, Horner plot to determine static temperature can be generated
1
Can be used to determine temperature gradients
0
Requires use of small lithium batteries
Specification

Depth
With provision of depth file, temperature vs depth is deliverable.
Range
0-165 ºC
Temperature
A calibrated Temperature measurement.
Weight
180g
