OPEN HOLE LOGGING

For the open hole logging, the software-controlled hardware system AMC MAGIS-2 is used.

Description

AMC MAGIS-2 is designed for surveys in prospecting, exploratory, and production oil and gas open-hole wells with the diameter from 120 to 250 mm and depth up to 5000 m. These surveys are carried out by means of electrical, radioactive, and sonic logging techniques, high frequency induction isoperimetric sensing, directional survey, profilometry, thermometry, and coupling localization. 

AMK MAGIS-2 provides quality digital data using laterologging, guard-electrode logging, electrical survey, SP, micro laterolog, microlateral sonde, and inductive electro-magnetic logging, resistivimetry, thermometry, CCL, profilometry, directional survey, gamma-ray log, natural gamma-ray spectrometry, 2TDTL, gamma-ray neutron log, density log, acoustic velocity logging, and VIKIZ-M under the maximum well temperature of +120°C and the hydrostatic pressure of 80 MPa.

Design options:

а) LL + GEL + IEML (5 probes) + inclinometer + SP
b) NGL+2TDTL +GRNL+GRL+MCL+АVL+MLL+ML+PB+VIKIZ+SP

Tasks

  • assessing oil and gas saturation of collectors in cross sections of drilled uncased oil and gas wells using methods of electrical sensing;
  • assessing flow and volume properties of drilled uncased oil and gas well columns by radioactive, sonic, and induction logging;
  • well integrity study by means of profilometry and spatial orientation of a well by means of directional survey;
  • monitoring process parameters: axial load on the head of the well device, temperature and pressure of the surrounding environment;

Advantages

  • Saving all logging data in the internal memory of the telemetry module, without any information losses in the logging cable, with the possibility of subsequent rapid downloading (1 Gb in 8 minutes);
  • Complete logging in one round-trip operation;
  • A fast intermodule interface with a universal data transfer protocol.  Adaptive telemetry for any type of logging cable.
