The equipment was development by AO NPP VNIIGIS in cooperation with AO NPF GITAS
is designed to determine rock electrical resistivity azimuthal distribution within a borehole with the scanning focused lateral logging sonde array.
Problems to be solved
Open well bore:
- geological formation azimuthal heterogeneities estimation;
- determination of layer bedding elements (dipmeter logging);
- reservoir quality discrimination and estimation of their anisotropy by electric properties;
- identification of vertical fracturing.
- strata inclination determination.
Cased well bore:
- Control of string technical condition;
- Detection of perforation holes, including slatted and drilling perforation.
