SCOPE OF APPLICATION
- Oil and gas wells, with/without tubing
- Operating or killed wells
- Any lithology
- Heavy or light cement
- Well filling - gas/water/oil
FEATURES
Multiparametric studies realized in one trip:
- Compensated Neutron Log to determine water saturated porosity, neutron parameters of the environment
- Three-probe spectral neutron gamma-ray logging for radial (3 logging depths) determination of elemental composition, nuclear parameters of the medium
- Spectral gamma-ray logging to determine K, U, Th concentrations
ADVANTAGES
- Express quality evaluation of cement filling behind two pipes (including accumulation of gas, water)
- Formation evaluation: saturation, porosity; by indirect parameters: density, permeability;
- Evaluation of formation lithology
