Purpose: downhole measurements of apparent resistivity (AR)
of rocks by two compensated induction sondes ("61" - of large
investigation depth LID and "80.9" of middle investigation
depth MID) & lateral microsonde.
Must to use with system control block "111"

The basic technical parameters:

1.AR interval, ohm-meters
-for induction sondes: 0.2 - 200
-for lateral microsonde 0.2 - 1000
2.The error bound, p.c. (%)
-for induction sondes: +-(5,0 + 0,2r)
where: r - real measurement, ohm
-for lateral microsonde: +-10
3.Diameter of device no more 75 mm
4.Device length no more 7.5 Meters
5.The investigation depth, M
-for LID induction sonde: 1.65
-for MID induction sonde: 0.85
-for lateral microsonde: 0.4
6.Device weight no more 130 Kg
7.Max environmental temperature 120C (175C)
8.Max environmental pressure 100 (120) MPa
9.Time of using in Max environmental temperature
no less then 8 hours (3 hours)
10.The measurement velocity no more 800 M/h
