Mud volcanism is a combination of the processes causing lifting and eruption to the surface via water channels clay masses and pieces of hard rocks which have been softened by underground waters. Mud volcanoes are mainly found in the areas of oil and gas fields where thickness of the sedimentary crust is high and there are shale layers in the stratigraphic section which serve as cap rocks for those fields. Presence of the shales is required for development of mud volcanoes. Areas of mud volcanoes development territorially related to the zones of oil and gas accumulations where discovered oil and gas fields on current stage of exploration are mainly referred to the Mid-Miocene – Pliocene age of the stratigraphy.

Aim of the analysis of scientific materials defined indirect relation between mud volcanoes and exploration of oil fields.

Keywords: mud volcano, oil, gas, breccia, eruption, clay
