A producing field is a long-running experiment that cannot be repeated. Decisions taken early — well spacing, depletion strategy, whether to inject and when, what data to acquire while it is still cheap to acquire it — constrain everything that follows. Recovery factors across otherwise similar fields vary by a factor of two or more, and a substantial part of that variation traces to management practice rather than to reservoir quality.

Effective reservoir management has a recognisable shape. There is a documented understanding of the reservoir and its drive mechanism, updated as evidence accumulates. There is a plan with a depletion strategy and identified decision points. There is a surveillance programme that measures the quantities the plan depends on, at a frequency that allows deviation to be detected while it can still be acted on. There is a process for deciding when observed behaviour is different enough from expectation to require the plan to change. And there is an organisation capable of acting on that finding.

What defeats this in practice is rarely technical difficulty. It is surveillance data that is acquired and never analysed, plans that are written for a development approval and never revisited, studies commissioned to answer questions nobody will act on, uncertainty acknowledged in a report and ignored in the decision, and knowledge that leaves with the engineer who held it. This course covers both the technical framework and the working practices that determine whether it functions, for engineers who are taking on responsibility for a reservoir rather than for a piece of analysis.

By the end of this training, participants will be able to:

• Establish a reservoir management framework and produce a reservoir management plan for an asset
• Design a data acquisition strategy justified by the decisions the data will support
• Build surveillance programmes covering pressure, production, injection and fluid behaviour
• Diagnose reservoir performance deviation from expected behaviour and determine its cause
• Develop depletion strategy including drive mechanism management and secondary recovery timing
• Apply well and reservoir management practice including intervention selection and infill planning
• Structure and scope integrated reservoir studies and specify what they must deliver
• Manage subsurface uncertainty explicitly through the decision process
• Apply reserves governance, classification and reporting requirements to an operating asset
• Organise asset team working, technical assurance and knowledge retention around the reservoir

The course is delivered as a practice-oriented programme built around the management of an operating reservoir through its life. Each subject is developed through what the manager must decide and what evidence supports that decision, rather than through calculation alone. Case material follows fields from development through plateau, decline and secondary recovery, including assets where management practice materially changed the recovery outcome and assets where it did not. Participants work through management decisions with incomplete information, which is the condition under which these decisions are actually made.

Organisations sending participants to this training will:

• Improve recovery factor through systematic reservoir management rather than reactive response
• Acquire the data that supports decisions and stop acquiring data that does not
• Detect reservoir performance deviation early enough to act on it
• Improve the quality and consistency of reservoir management plans across assets
• Strengthen reserves governance and the defensibility of reported volumes
• Retain subsurface knowledge across staff changes and organisational reorganisation

Participants will:

• Move from performing reservoir analysis to managing a reservoir
• Design surveillance and data acquisition programmes that earn their cost
• Diagnose why a field is not performing as expected and decide what to do
• Lead integrated studies and specify what they must deliver
• Make and defend reservoir decisions under uncertainty
• Take on senior technical and asset accountability roles

• Reservoir engineers moving into asset and management responsibility
• Senior reservoir engineers and reservoir engineering team leads
• Petroleum engineers with field and asset accountability
• Production engineers working closely with reservoir management
• Development geologists and geoscientists in asset teams
• Reserves and technical assurance specialists
• Subsurface and asset managers responsible for field performance

Upon successful completion of this training course, delegates will be awarded an official Certificate of Completion issued by the Petroleum Engineers Association (PEA), an ISO 9001:2015 certified training organization. The certificate carries 10 Credits and formally records the total learning hours completed.

Each certificate is signed by the Course Facilitator and the CEO of the Petroleum Engineers Association, and serves as verifiable proof of professional training that delegates can present to employers and professional bodies worldwide.
