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.

Description

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)*.

*tailor-made one-core cable tool is available
