Integrated sound reservoir management is the key to a successful operation
throughout a reservoir’s life.

Reservoir management:
Utilization of available resources (i.e., human, technological
and financial) to maximize profits/profitability index from a
reservoir by optimizing recovery while minimizing capital
investments and operating expenses.
Main purpose:
To control operations to obtain the maximum possible
economic recovery from a reservoir based on facts,
information, and knowledge.

5
The prime objective of reservoir management is the economic
optimization of oil and gas recovery, which can be obtain by the
following steps:
➢Identify and define all individual reservoirs in a particular field
and their petrophysical properties
➢Deduce past and predict future performance of reservoir
➢Minimize drilling of unnecessary wells
➢Define and modify (if necessary) wellbore and surface systems
➢Initiate operating controls at the proper time
➢Consider all pertinent economic and legal factors

6
When should reservoir management start?
The ideal time to start managing a reservoir is at its discovery. Early initiation
of a coordinated reservoir-management program not only provides a better
monitoring and evaluation tool, but also costs less in long term. For instance, an
additional time on a DST may provide better information than more expensive
core analysis. Besides, some early tests can indicate the size of a reservoir. If it
is of limited size, drilling of unnecessary wells can be prevented.

7
What, how, and when to collect data?
➢ Are the data necessary, and what are we going to do with these data?
➢ What decisions will be made based on the results of the data collection?
➢ What are the benefits of these data, and how do we devise a plan to obtain
the necessary data at the minimum cost?

8
The modern reservoir management process involves setting,
planning, implementing, monitoring, evaluating, and revising
plans.
❑ Setting a reservoir management strategy requires knowledge of
the reservoir, availability of technology, and knowledge of the
business, political, and environmental climate.
❑ Formulating a comprehensive management plan involves
depletion and development strategies, data acquisition and
analyses, geological and numerical model studies, production
and reserves forecasts, facilities requirements, economic
optimization and management approval.

9
❑ Implementing the plan requires management support, field
personnel commitment, and multidisciplinary and integrated
teamwork.
❑ Success of the project depends upon careful
monitoring/surveillance and thorough, ongoing evaluation of
its performance.
❑ If the actual behavior of the project does not agree with the
expected performance, the original plan needs to be revised,
and the cycle (i.e., implementing, monitoring, and
evaluating) reactivated.

Recognizing the specific need and setting a realistic and
achievable purpose is the first step in reservoir management.
The key elements for setting a reservoir management goal are:
❑ Reservoir characteristics
❑ Total environment
❑ Available technology
Understanding of each of these elements is the prerequisite to
establishing short- and long-term strategies for managing
reservoirs.

12
Understanding the nature of the reservoir requires a knowledge of
the geology, rock and fluid properties, fluid flow and recovery
mechanisms, drilling and well completions, and past production
performance.

Understanding of the following environments is essential in
developing management strategy and effectiveness:
❖ Corporate goal, financial strength, culture, and attitude
❖ Economic-business climate, oil/gas price, inflation, capital and
personnel availability
❖ Social conservation, safety, and environmental regulations
14

15
The success of reservoir management depends upon the reliability
and proper utilization of the technology being applied concerning
exploration, drilling and completions, recovery processes, and
production.

Once the goals and objectives have been set and an integrated
reservoir management plan has been developed, the next step is to
implement the plan.
➢ Start with a plan of action, involving all functions
➢ Flexible plan (adaptable to surrounding circumstances)
➢ Management support
➢ Commitment of field personnel
➢ Periodic review meeting, involving all team members (teach
each others)

21
An integrated and comprehensive program needs to be developed
for successful monitoring and surveillance of the management
project. The major areas of monitoring and surveillance involving
data acquisition and management include:
➢ Oil, water and gas production
➢ Gas and water injection
➢ Static and flowing bottom hole pressures
➢ Production and injection tests
➢ Injection and production profiles

22
The plan must be reviewed periodically to ensure that it is being
followed, that it is working, and it is still the best plan. The
success of the plan needs to be evaluated by checking the actual
reservoir performance against the anticipated behavior.
