The method in this paper is more accurate compared with conventional point-source solution, and can handle the transaction from transient flow to pseudo-steady state flow smoothly. The results of the study show that in low permeability formation, hydraulic fracturing...

When the pressure, either in the wellbore or in the reservoir, drops below the dew point pressure, a liquid condensate phase appears and reduces gas production...

Digital image processing techniques are applied on the recorded images not only for volumetric phase distribution inside the test section, but also...

... Abstract Propellant-assisted perforating systems are used to stimulate the near wellbore region and to alleviate the formation compaction damage from the perforating event. This method involves combining a perforating gun with a high pressure, gas generating propellant. Detonation...

The pumping rate and water production rates were accurately estimated by matching the bottomhole temperature through the numerical simulation using a wellbore model. In 2008, much larger and longer gas production was accomplished with a stepwise reduction of the bottomhole...

... Abstract Non-equalized production influx along the horizontal or inclined wellbore is believed to be responsible for early water/gas breakthrough in oil production wells. Non-equalized water injection distribution has been recognized to cause poor sweep efficiency in waterflooding. The non...
