BGW light is a lightweight and compact winch designed for geophysical well logging using various methods. It is equipped with high-capacity drum with a built-in electric drive and a slip ring. The gear motor is controlled by a connected remote control unit allowing to adjust the speed of the winch drum rotation. The winch can be powered by both external and built-in batteries. It is quick and easy to switch to the manual operations mode with a drive through a gear-motor, and there is a convenient stopper on the handle. The counterweight can be easily attached to the winch and can be optionally equipped with a manual winch roller.

BGW lightwill weigh several tens of kilograms. At greater depths, it is better to use a power cable with a large cross-section of the core in order to balance the energy loss due to the ohmic resistance - it is only possible to work with such a line using a BGW or BGW light winches. Winches of this type can be equipped with built-in high voltage or stranded slip rings to ensure the operation of borehole sparker Pulse or borehole hydrophone (WellStreamer) and geophone (GStreamer) arrays.

BGW light application areas:
  • Borehole seismic surveys using CST, VSP, VSaP, sonic logging, etc.
  • Borehole electrotomography
  • Geophysical well logging using non-seismic methods
