Ladies and Gentlemen, POISK Science and Production Association is happy to welcome you at our website!
The main scope of our organization's activities covers development, manufacture and sale of echolocation ultrasonic well-logging instruments designed for determination of well geometry, as well as environmental geological monitoring of underground chambers with the Scanner-2000 well-logging instrument. Fast and accurate identification of dimensions, shape and spatial arrangement of underground dissolution chambers determines efficiency of managing the salt production process and rational use of mineral resources. The SCANNER-2000 well-logging instrument is meant for determining dimensions and shape of chambers forming at borehole salt recovery. The instrument's operating principle is ultrasonic location.

Key technical specifications:
1. Maximum measured distance obtained through ultrasonic location in the
||Minimum measured distance (by conditional radius)
3. Distance measurement error (for ground check),
at distance up to 5 m, max
||Azimuth angle error as referenced by the geomagnetic field, max
||Permissible external hydrostatic pressure, max
||liquid (NaCl brine)
||Operating temperature (of working medium)
a) diameter, max.
b) length, max.
||Length of logging cable
||Supply voltage (AC 50Hz)
||Power consumption, max.
||Service life, min
||Profile registration time, max.
||The time of profile registration is max.
Registration, processing and 3-D visualization of measurement results are fulfilled with an IBM-compatible PC on the real time scale through the standard PC interface (LPT-, or COM-port). Preliminary processing of results includes intelligent algorithms of screening out interference signals and multiple reflected waves, restoration of missing measurement data, profile smoothing and adjustment based on a priori information from survey measurements. The processing software calculates the principal parameters of profile: area, maximum and minimum radii, profile decentration, factors of profile shape deviation from the perfect one, which makes it possible to assess the level of anisotropy of the washout process. The software provides tools for 2-D and 3-D visualization, comparing profiles of different levels and different washout stages.

The instruments have been successfully operated: since 1998 - at the MOZYRSOL brine recovery site, since 2002 - at the SAYANSKKHIMPLAST mine, since 2006 - at BelTransGaz gas depots, since 2007 - at the SODA brine recovery site; since 2000, they have been successfully used at oil storage facilities, and for cases of waste storage washout; in China - for cases of technologically complicated column conditions, including measurements taken through the column.
With hope for fruitful cooperation,
