The principal component of the drainage aid is a surfactant, which can reduce the surface tension between the oil and gas phases and the water phase, increase contact angles with rock surfaces, reduce the capillary forces within reservoir pores, and thus reduce the starting pressure necessary to overcome the water blocking during …
Reservoir fluid properties
Water viscosity is a measure of the resistance to flow exerted by water. Higher values indicate more resistance to flow. For water, the viscosity decreases with increasing temperature, and increases with increasing pressure. Water viscosity is a very weak function of pressure. Water at room temperature is approximately equal to 1 cP.
Experimental Investigation of Cooling Effects Resulting From …
Initially, when injecting cold, high pressure CO2 into a hot low pressure environment, heat transfer from the surrounding reservoir environment will mask or counter Joule-Thomson gas expansion cooling effects. The most significant early-time cool down effect may be the result of injecting a cold fluid into a hot reservoir.

Faults in CO 2 storage reservoirs affect the migration and spatial distribution of injected CO 2 in reservoir formations. Based on geological data from the Ordos CO 2 geological storage demonstration project site, A 2D numerical model of the CO 2 storage reservoir was constructed to study the influence of high-porosity and high …

PEH:Gas Reservoirs
In addition, low-permeability reservoirs can have significant pressure differences across the field because certain areas can be drained more effectively than others. Poston and Berg [17] discuss methods for adjusting p / z plots for the lack of sufficient buildup time in determining average reservoir pressures.
Production decline curves for low-pressure gas reservoirs …
A family of production decline curves for low-pressure gas reservoirs are presented for radial flow geometry with closed outer boundary and with a centrally located well. The proposed production decline curves are applicable to conventional gas reservoirs that produce gas and water simultaneously.
