... Abstract Concurrent gas and oil production from the Virginia Hills Belloy Shunda Unit #I Unit wan considered. A full field simulation study was used to evaluate the impact of initiating early blowdown of the gas cap. An excellent match of the production, pressures and two-phase interface...

... the gas-oil contact is actually in a two-phase (gas-liquid condensate) state. This has significant implications as the initial oil-in-place of the gas condensate reservoir is much higher than previously expected due to initial liquid saturation in the gas cap in addition to condensate held in the gaseous...

... and controlled by dolomization and fracturing. There is a down dip water leg and early testing indicated the presence of an up dip gas cap. The production performance of the field was difficult to evaluate, in particular, water production. Numerical modeling (simulation) has given significant insights...

... Abstract The performance of a horizontal well in the presence of a growing cone before breakthrough is studied. Examining the flow mechanism in rese11loirs with bottom water or gas cap, we consider the interface as a no-flow moving boundary before breakthrough. The paper presents...

... cap, overlying an aquifer or both, Coning occurs in a well on production, when the water or gas zone moves up towards the wellbore in the form of a cone. Eventually, the water or gas breaks through into the well and water from the aquifer and/or gas from the gas cap is produced along with oil...

... Abstract The first horizontal wells in the Prudhoe Bay Unit were drilled in the central gravity drainage area to increase standoff between the wellbore and the gas cap for improved recovery and increased production rates. Subsequent applications of horizontal wells have included producers...

.... The reservoir. which forms part of the prolific Leduc Reef Chain, is one of the most capable producing fields in Canada. The original oil-in-place is estimated to be 657,138,000 stock tank barrels with an original gas cap of 444.900 million cubic feet. The recovery mechanism is primarily gas cap expansion...
