BGW is specifically designed for seismic acquisitions in relatively deep wells, when cable and borehole equipment weight do not allow to perform convenient and safe operations.

Even with a borehole depth of 100 m, a standard coaxial cable with a 10-mm² cross section will weigh several tens of kilograms. At depths of several hundred meters, the use of a power cable with a large cross section of the core is required to balance the energy loss due to the ohmic resistance - it is only possible to work with such a cable using a BGW winch.

Depending on the acquisition type, BGW can be equipped with high-voltage or low-voltage multicore slip rings to ensure the operation of the borehole sparker Pulse or borehole hydrophone (WellStreamer) and geophone (GStreamer) arrays. A powerful electric gear motor allows adjusting the speed of the winch drum rotation and fix the equipment at the desired depth. In case of a power cutoff, manual winch operations can be performed. Additional convenience of work is provided by a universal manual winch roller and an integrated counterweight with a wide range of adjustments for various wellheads.

BGW dimensions and the detachable counterweight with the winch roller make its transportation easy and allow one to perform field operations with a stationary winch installed in the back of a pickup truck, a trailer, or a minibus.
