The impact of geological environment on pipeline systems in the area of stray current

It is proposed to apply a set of geophysical methods to engineering surveys when designing and operating linear underground constructions of pipeline transport. The study allows for identifying the area’s best fitting for laying and operating the pipeline transport system. The paper provides a complex of geophysical methods to guarantee safety standards on the pipeline transport systems when affected by natural and anthropogenic hazards.

Electrical methods, such as symmetrical electrical profiling, gradient potential method and self potential method, were used to identify possible areas of corrosion on the underground oil pipeline «Kremenchuk-Herson». Research the effect of stray current on steel pipe. The low apparent resistivity and high negative spontaneous potential values are indicated that the soil is very corrosive and there is the possibility of the pipeline failure in the future. Electrical geophysical investigations along buried pipelines should be undertaken for the early detection and prevention of pipeline failure with its negative environmental and economic consequences.
