Assignment

Subject: Enhanced Oil Recovery

Due date: Feb. 4, 2010 before 5pm (please upload in the eLearning)

Welge Method

Data Summary

Injection Rate Qi 1200 bbl/d/well
Water viscosity w 0.5 cp
Oil viscosity µo 4.5 cp
Initial water saturation Swc 0.2
Residual oil saturation Sor 0.2
Porosity 0.22
Dip angle θ 0
Reservoir thickness H 50 ft
Distance between injection wells W 800 ft
Distance-injectors & producers L 2000 ft

Questions:

  1. Find the Time break through
  2. Estimate the time and the water amount needed to recover 80% of oil
  3. Plot average saturation vs cumulative water, injected from t=0 until abandonment

Answer must be in the .xls format

Good Luck!!!
