Survey of Oil Sludge

The purpose of the GPR survey is to estimate the volume of oil sludge. The oil sludge collector is a hollow bounded by two dams. GPR profiling was carried out by the antenna with a central frequency of 100 MHz in the winter time in the frozen surface of the sludge collector. The figures below show the antenna unit of the GPR, located in a specialized radio-transparent sled, as well as a towing device, which ensures a uniform speed of the GPR profiling:
