Study of this subject is directed at these fundamental thematic spheres of action – methods for the determination of basic physical characteristics of reservoir rocks, liquids and gases, primer of technics and technology used by liquid and gas production, flow intensification, secondary and tertiary production methods, collecting, transport and treatment of hydrocarbons, underground well repairs, methane output using surface coal-seam degassing, effect of a production activity upon an environment.
The part „Drilling technologies“ is intent expecially on these thematic spheres of action – the basic kinds of boreholes drilled in underground conditions, methods of their realisation and the purposes of their utilization. Drilling technics and technological processes utilized during drilling boreholes in underground – main function blocks (units) of drilling machines, geological exploratory and operative technical boreholes, safety boreholes drilled in underground – degassing, dewatering, geotechnical boreholes, large – diameter drilling in underground, new technologies and technical means used by drilling underground boreholes, drilling using down – the – hole hammers, new trends in drilling technologies.
