E.O.R

Why are we doing this??

• Primary oil recovery: can only recover 10 to 20 percent
• Secondary oil recovery: 20 to 40 percent.
• Tertiary oil recovery: 30 to 60 percent.
• Undeveloped domestic oil resources still in the ground.

% Recovery

Primary Oil Recovery

• The initial stage of producing oil from a reservoir.
• Use Natural Forces such as: 1- Expansion of oil, gas or both. 2- Displacement by naturally pressurized water. 3- Drainage from a reservoir in high elevation to a well in lower elevation. 4- Artificial techniques (pumps).

Secondary Oil Recovery

• Injection of fluids in a series of wells to force oil into another series of wells (essentially augmenting the natural forces used in primary methods).
• 1- Water flooding 2- Gas Flooding
