AN INTEGRATED PLAN OF DEVELOPMENT TO OPTIMIZE PRODUCTION OF FIELDS

OPPORTUNITY AND CHALLENGES

Many Brownfields. Most of (about 80%) Indonesia oil production comes from depleted reservoir.

Field Development: The sequential approach vs multidisciplinary approach

Big Issue No team work

◦ Lack of communication, sharing info, comprehensive understanding

◦ Lack of esprit de corps

No Teamwork

Teamwork

Specific Objectives

Understand comprehesively whole process of Plan of Development of a Field

Understand the importance of team work in the making of POD Understand to obtain necessary data and how to analyze Be able to do reservoir engineering analysis, production analysis and economic analysis for a POD.

Understand the theoretical bacground as well as field implementation for each discipline.

Be able to give recommendation to the management for field development.
