Prospecting for karst disturbances using electrical exploration methods

Abstract
The industrial oil-shale bed of the Leningradskoye field is confined to the Kukruse horizon of Ordovician limestones. The thickness of the overlying strata varies from 50-60 m in the north to 80-100 m in the south. In the northern part, Ordovician limestones occur directly under Quaternary sediments; in the southern part, in addition to Quaternary sediments, they are overlain by Middle Devonian sediments (marls, sands and clays). The thickness of Quaternary sediments is on average 5-10 m.
