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 wire line of 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 at the ohmic resistance - work with such a line is possible only with the use of BGW winch.

Depending on the acquisition type, BGW can be equipped with high-voltage or low-voltage multicore sliding contacts to ensure the operation of the Pulse downhole sparker or WellStreamer and GStreamer downhole recording systems. A powerful electric gear motor allows you to adjust the speed of rotation of the winch drum 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 counterweigh 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 you to perform field operations with a stationary winch in the back of a pickup truck, trailer or minibus.
