Characterization of Flow Behaviour in a Crude Oil Production Well

The estimation of pressure drop in vertical wells is not just important, it's a critical aspect.

Reservoir production capacity depends on Reservoir Pressure, Thickness and Permeability of the Production Zone, Type and Spacing of Reservoir Boundaries, Well Radius, Reservoir Fluid Properties, Near Well Conditions, and Relative Permeabilities of the Reservoir.

Reservoir production capacity can be mathematically modeled based on flow regimes such as transient flow, steady-state flow, and pseudo-steady flow. These models can describe how a reservoir produces hydrocarbons as a function of variations in pressure and other parameters.

The well's flow rate as a function of bottom pressure characterizes the flow through the reservoir, and this defines the well's behavior curve (IPR—"Inflow Performance Relationships").

To moddeling to oil well production I analysis the mechanical skin factor calculated using the Karakas and Tariq (1991) to the diameter of the perforations of 10 mm and the length of a performance of 152.4 mm and the diameter of the perforations of 40 mm and the length of a perforation of 1270 mm for the Duns & Ros, Orkiszewski, Hagedorn & Brown, and Beggs & Brill correlation.

This paper addresses the procedures for establishing IPR curves for various reservoir types and well configurations.
