Battery Module

Compass uses high-energy Lithium Thionyl Chloride double-D size batteries in a stack of eight with a 175°C (350°F) temperature rating. The cells are diode protected to prevent reverse power charges, and are protected by a 5 Amp fuse on the power line. With a Compass Stepper Pulser, a battery pack will operate the MWD system for over 450 hours and over 300 hours with an added gamma probe.

 

The design of our system allows for the addition of a second battery pack that will be activated when the power of the first battery drops to a predetermined level. This allows the operator to place the batteries in various positions in the MWD tool design. This option allows the users to determine the optimum position of the directional module determined by magnetic spacing requirements. The use of flexible finned intermodule connectors allows multiple design options on the MWD system with the standards being to place the pulser on the bottom (required) and the gamma and directional module located at the optimum positions.

 

The Battery Module is 68.9″ (1.77 m) in length and weighs 28 lb (12.7 kg).
