Various types of geological exploration (field and borehole geophysical surveys; drilling, development and operation of wells, operation of underground facilities) are associated with certain geoecological risks. This problem is typical for most regions of the world and Russia, including regions (Volga-Ural, Caspian, West Siberian, East Caucasian, etc. Geological exploration work has a significant impact on the environment, which is expressed in the destruction of sedimentary rocks, oil spills, pollution of the atmosphere, soil layer, groundwater; the formation of significant volumes of production waste, in particular, drill cuttings, which are stored in the adjacent drilling area. A special geo - ecological hazard is posed by the process of drilling a well, which is accompanied by various accidents, oil and gas outbursts, brines, pollution of rocks and groundwater, changes in natural landscapes and the underground geological sphere. Well development processes are environmentally hazardous, in which wells are blown off and a significant volume (tens of thousands and million m3 per year) of gas is released into the atmosphere and its pollution, as well as the operation of landfills for solid and liquid production wastes, underground gas storage facilities, etc. The article substantiates the geoecological risks during geological exploration. To minimize geological and environmental risks during geological exploration, the use of equipment and technologies that meet the most stringent environmental and industrial safety requirements is required

Key words: geocological safety, risks, brine showings, rock cuttings, drilling mud, waste, landfills
