Introduction

Oil recovery operations traditionally have been subdivided into three stages

Primary Secondary Tertiary or EOR

Oil Recovery

Oil Recovery

Primary Secondary Tertiary or EOR

Oil Recovery

Primary Recovery

The initial production stage, resulted from the displacement energy naturally existing in a reservoir.

• Natural Flow

• Artificial Lift

Oil Recovery

Primary Secondary Tertiary or EOR

Oil Recovery

Secondary Recovery

The second stage of operations, usually was implemented after primary production declined.

• Waterflood,

• Immiscible gas injection

• Pressure maintenance

Oil Recovery

Primary Secondary Tertiary or EOR

Oil Recovery

Tertiary Recovery

The three major EOR methods are:

• Miscible (mixing of oil with a solvent)

• Chemical (flooding with chemicals)

• Thermal (application of heat)

Exploration and Production

Recent price increases have led to oil exploration and production in areas where extraction is much more expensive:

Extremely Deep Wells, Extreme Downhole Temperatures and Pressures Depleted Oil and Gas/Condensate Reservoirs Heavy Oils Oil Sands Shale Oil and Shale Gas Environmentally Sensitive Areas

High technology is required to extract the oil and gas. 8
