Description

Features and Advantages

• the tool is operated through a one-core cable of up to 6000 m in length, with computerized logging stations equipped with fast-acting analog-digital converters which allow to record the full wave picture (of GEKTOR type);
• the tool admits the conveyance to the investigation interval through the drill pipe (inner diameter 2.5″);
• the tool allows to measure elastic wave dynamic and kinematic parameters as well as acoustic noise and temperature.
