Mathematical modelling of thermal stresses within the borehole walls in terms of plasma action
(Dnipro University of Technology, 2021-06-30)
Purpose is the development of a mathematical model to study and describe thermal processes within the borehole wall in
terms of plasma-based rock breaking.
Methods. The following has been applied: theoretical analysis ...
Analytical modeling of mine water rebound: Three case studies in closed hard-coal mines in Germany
(Dnipro University of Technology, 2021-09-30)
Purpose. In this paper we present and validate an analytical model of water inflow and rising level in a flooded mine and
examine the model robustness and sensitivity to variations of input data considering the examples ...
Studying the influence of the carbon dioxide injection period duration on the gas recovery factor during the gas condensate fields development under water drive
(Dnipro University of Technology, 2021-06-30)
Purpose. Studying the process of carbon dioxide injection at the boundary of the initial gas-water contact in order to slow
down the formation water inflow into producing reservoirs and increase the final hydrocarbon ...
Factors influencing the flooding process of former coal open-pits
(Dnipro University of Technology, 2021-06-30)
Purpose. This study aims to identify the main factors that influence the flooding process of the remaining gaps of open-pits
comprising essentially the velocity and duration of flooding, but also the stability of in situ ...
