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!
