CONSTRUCTING AN EXPERIMENTAL EQUIPMENT FOR TESTING THE INFLUENCE OF NATURAL GAS – HYDROGEN MIXTURE ON THE PRODUCTION TUBING
Veselin Mitkov
An experimental equipment is constructed for testing the effect of gas-hydrogen mixture at different % hydrogen and methane contents (5%, 15%, 25%) on the steel tubing used for production and injection of gas wells for underground gas-hydrogen storage. The pre...

NEW TECHNOLOGY FOR DEVELOPING HYDROCARBON RESERVES OF COMPLEX RESERVOIRS WITH UNDERLYING WATER
Miel Hofmann, Sudad H. Al-Obaidi, Igor P. Kamensky
This study presents a novel technique for developing complex oil reservoirs with bottom water. The method involves injecting freshwater below the oil-water contact (OWC) and subsequently stabilizing it with a polymer to create a barrier. This approach is desig...
