Features and benefits
Wireless/Wired communication system equipment on the ground.
Power supply modules downhole TeleSystems is carried out by means of a block of lithium battery.
The design of bottom-hole telemetry MWD allows the connection of additional modules of gamma-logging, the unit of the lithium batteries.
