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
