... is to study the effects of different modeling strategies on scale-up. In an analytical approach, permeability values are averaged or scaled up by using selected mathematical averaging method. The scale-up results obtained from these methods depend only on the distribution of permeability values in reservoir...

... for scaling permeability of a reservoir formation is the average method. Begg et al .2 determined that harmonic and arithmetic methods gave the lowest and highest values, respectively, of average permeability and the geometric method provided results between the values from harmonic and arithmetic methods...

Surprisingly, in many reservoirs, initial fluid saturations are virtually unknown or improperly measured, resulting in gross over or under estimation of oil or gas reserves in place...

... cutting oil production by a factor of 4 times due to relative permeability effects. Gas rates even as low as 5 e3m3/d affect oil production of less than 5 m3/d. Load fluid clean-up can also be a problem due to low energy flowbacks. saturation annual technical meeting undersaturation stimulation...

... be used to analyze the reservoir performance and to estimate some reservoir parameters such as reservoir thickness, permeability, and the trend of the increase or decrease of the productivity along the wellbore. In well testing of horizontal wells with constant length, the effect of the reservoir...

... Abstract Pressure transient testing techniques such as pressure buildup, pressure drawdown, and constant rate injection have been used in petroleum industry for well performance evaluation and reservoir characterization. Conventional method of analysis usually assumes that permeability...

... and production in tighter, less permeable zones, the damage-while-drilling issue becomes extremely important. The objective of this paper is to present and discuss the methodology and testing results used in selecting a drilling fluid to be employed in drilling a horizontal well in the Cardium gas reservoir...

... Abstract Accurate relative permeability data are essential for predicting the performance of two-phase flow through porous media. Many factors, such as the rock and fluid properties, may affect the measurement of relative permeability. However, the saturation levels of the fluids flowing...

... Abstract Adequate numerical prediction and forecasting of reservoir performance rely on the knowledge of relative permeabilities. In gravity driven processes the flow is complex, consisting of co-current and counter-current flows. This work describes the characteristics of gravity driven flow...

If conduits for water flow are available then they need to be blocked in order for production wells to continue operation. In terms...

This exploitation technology is already being applied in Europe and, in a more limited extent, in the U.S. Its application in Canada is currently being tested and/or evaluated by several...

... Abstract Injection of water into reservoirs are very common in petroleum industry. For examples, produced water is disposed into deep, permeable reservoirs. In water flooding recovery process, water of huge volume is injected into reservoir to displace oil-in-place to nearby producers...
