is designed for hole director cementing quality control and investigation of sections in large-size open holes by kinematic and dynamic parameters of elastic waves.
Problems to be solved
- weak cement interval determination and cement matrix bulk-contact defects definition;
- lithologic layering and reservoir identification and porosity estimation.
Features and Advantages
- large-size hole investigation;
- the tool is operated through a triple-core cable of up to 6000 m in length, with the computerized logging stations equipped with fast-acting analog-digital converters which allow to record the full wave picture (of GEKTOR type)*.
