Features and Benefits.
Wireless / Wired Ground Equipment Communication System.
The power supply of the downhole modules of the telesystem is carried out by means of a lithium battery unit.
The design of the downhole telemetry telemetry system allows connecting additional gamma-ray logging modules and a lithium battery pack.
Operating conditions.
The sand content in the solution is ˂1.0%.
The admissible diameter of the solid fraction in the solution is 2 mm.
Mud viscosity ≤140.0 sec.
Mud density ≤1.7 g / cm 3
