But What Does Reservoir Management Mean? •

An ongoing continuous PROCESS

•

Developing and depleting resources in a manner MAXIMIZING benefits, advantages, and economic recovery

•

Judiciously employing time and manpower resources while MINIMIZING waste

•

OPTIMIZING the process using current technology

Why Do We Need Reservoir Management? • A reservoir can be produced only once – Many production options exist • Some reservoir processes are irreversible – Reserves can be irretrievably lost • Arbitrary development / production scheme can be harmful – Contrary to established objectives or constraints – Adversely affect recovery • Some data can only be obtained at certain points in a reservoir’s life
