Assignment #2

1. Describe about flowrate based on the flow regimes in the reservoir! (Transient flow,

Steady-state flow, and Pseudo-Steady-State flow)

2. Construct IPR of a vertical oil well in an oil well reservoir. Consider (1) transient flow

at 1 month, (2) steady-state flow, and (3) pseudo-steady-state flow. The following data

are given:

Porosity (Φ) = 0.20

Effective horizontal permeability (kh) = 10.2 mD

Payzone thickness (h) = 63 ft

Reservoir pressure (Pe = ̅) = 6000 psia

Bubble-point pressure (Pb) = 1000 psia

Fluid formation volume factor (Bo) = 1.2

Fluid viscosity (µo) = 1.8 cp

Total compressibility (ct) = 0.0000129 1/psi

Drainage area (A) = 640 acres (re = 2980 ft)

Wellbore radius (rw) = 0.328 ft

Skin factor (s) = 0

3. Explain about Vogel’s IPR model, Fetkovich’s IPR model, and Composite IPR model!

(Min. 300 words)

4. Explain about Future IPR and give an example based on Vogel’s and Fetkovich’s!
