A New model of gas-water two-phase seepage based on Newton's law of motion [PDF]
HeliyonThe pore throat size, structure distribution, and lithology of porous media in gas reservoirs are varied, and the gas-water two-phase seepage law is complex, making it difficult to describe the seepage model.

Measurement of Water Velocity in Gas-Water Two-Phase Flow with the Combination of Electromagnetic Flowmeter and Conductance Sensor. [PDF]
Sensors (Basel), 2020 A method to measure the superficial velocity of the water phase in gas–water flow using an electromagnetic flowmeter (EMF) and rotating electric field conductance sensors (REFCSs) is introduced in this paper. An electromagnetic flowmeter instrument factor model is built and the correlation between electromagnetic flowmeter output and gas holdup in ...

The Effect of Drilling Fluid on Coal’s Gas-Water Two-Phase Seepage
Geofluids, 2022 In the process of coal bed methane (CBM) production, the output of CBM is mainly related to the relative permeability of gas and water in coal seams. However, during the drilling process, the invasion of drilling fluid into CBM reservoirs changes the ...

Numerical Simulation of Gas Injection to Increase CH<sub>4</sub> Production on the Basis of Gas-Water Two-Phase Flow. [PDF]
ACS OmegaGas injection to increase coalbed methane (CBM) production has triple benefits. In this paper, a coupled heat-water-force flow model is established to discuss the influence of different injected gases on enhancing the extraction of CBM, and the effects of mixture injection and injection temperature on gas production are analyzed.
