SureShot Power Options

The APS MWD system uses either battery pack(s) housed in APS battery module(s) or a turbine alternator, which can be run alone or in combination with battery module(s).

BATTERY MODULES

  • Use 10 x DD Lithium cells available from a number of approved suppliers.
  • Available in 20,000 psi (137.9 MPa) standard version with ToughMet™ barrels, plus 25,000 psi (172.4 Mpa) with Inconel 718 barrels.
  • Available with rubber fin centralization or pad centralization.
  • A novel approach to intelligent MWD batteries is coming soon from APS, featuring:
    • Improved battery switching and power management
    • Performance data logging – current draw, voltages, temperature and other parameters
    • Enhanced safety

Reliable and rock-steady power provides added confidence for any run length.

The APS Turbine Alternator† is a high-temperature, axial flow design for use in measurement-while-drilling (MWD) and logging-while-drilling (LWD) systems. This device provides reliable, ongoing power at temperatures of up to 175°C, taking the place of expensive, short-lived disposable batteries. The turbine is configurable to match the required flow rates for typical BHA/hole size combinations.

  • Provides rock-steady power over any run length.
  • Reduces or eliminates battery safety issues.
  • Reduces or eliminates depleted battery shipping and recycling costs.
  • Satisfies power requirements for advanced LWD services, which are problematic with batteries only.

† U.S. Patent #7,201,239
