is designed for rocks volume density estimation in section of oil-bituminous, ore and coal wells with a depth up to 5000 m and hole diameters ranging from 76 to 400 mm.

Description

Features and Advantages

• scattered gamma-ray measurements are conducted at two different distances from source;
• during measurements the sonde is clamped to the well side by the surface control system;
• wide range of measured density;
• absence of drilling mud/clay coating effects on the investigation result;
• cased-hole investigation.
