Abstract
This article describes ways of natural gas production from shales by means of drilling boreholes. Horizontal boreholes used for such purposes have been presented. Next, methods of acquiring geothermal heat were described, including both heat acquisition by means of thermal waters production, through borehole heat exchangers, and enhanced geothermal systems (EGS), particularly HDR systems, i.e. heat acquisition from hot dry rocks. The aim of this article is to present proposal of utilizing depleted shale gas wells for geothermal heat production. The way of heat provision, which is the most realistic, is deep borehole heat exchangers. They can be made using vertical sections of shale gas producing boreholes. The key issue is how to construct such exchangers. They should be made in the form of coaxial exchangers. Heating medium flow in such exchangers is downwards in an annulus space and to the surface inside the internal centric column. Insulation properties of such a column are of fundamental importance, due to energy efficiency of borehole exchangers. The column has to enable heating medium flow and thermally insulate reverse action streams with different temperatures. To this end, one can utilise pipes used for injecting steam to reservoirs in order to intensify production. In such pipes, thermal insulation is acquired by means of vacuum between two steel pipes. Such pipes are expensive and take a lot of place, thus limiting flow (higher flow resistance). Another solution is the application of plastics. Currently, at the Department of Drilling, Oil and Gas at AGH University of Science and Technology, works are carried out on the selection of plastic materials in terms of thermal insulation and mechanical resistance to high pressure. One up to a dozen boreholes are drilled from a single drilling position.
