Reservoir engineering is the discipline that converts a static description of the subsurface into a production forecast. A geologist and a petrophysicist describe the rock, its volume and its fluid content. The reservoir engineer takes that description, applies the physics of fluid flow and material balance, and produces the numbers on which the entire development rests: recoverable volume, production rate, well count, facility size and field life.

The methods used to do this have a long history and are well established. Volumetric estimation, material balance, Darcy flow and decline analysis were developed decades ago and remain the backbone of the discipline because they are grounded in conservation of mass and in measured reservoir behaviour. Numerical simulation extends them but does not replace them; the analytical methods remain the check that tells an engineer whether a simulation result is plausible.

Learning these methods by building them is the fastest route to real understanding. When an engineer assembles a material balance calculation cell by cell, the meaning of each term becomes clear, and so does the effect of getting an input wrong. This course is built on that principle. It assumes a technical background but no prior reservoir engineering specialisation, and it takes participants to the point where they can carry out the standard calculations of the discipline independently and explain what they mean.

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

• Define and apply the basic rock and fluid properties used in reservoir engineering calculations
• Calculate oil, gas and water PVT properties from standard correlations and check them against laboratory data
• Identify reservoir drive mechanisms from pressure and production behaviour
• Estimate oil and gas in place by volumetric methods and apply appropriate recovery factors
• Construct and solve material balance equations for oil and gas reservoirs
• Apply simple aquifer models to estimate water influx and assess aquifer strength
• Build inflow performance relationships for oil and gas wells and quantify the effect of skin and drawdown
• Perform fractional flow and frontal advance calculations to predict waterflood breakthrough and recovery
• Analyse production decline and estimate remaining reserves and field life
• Lay out reservoir engineering spreadsheets with separated inputs, consistent units and results that can be verified

The course is delivered as a structured teaching programme that moves from principles to calculation. Each topic starts with the physical behaviour being described, develops the governing equation to the level needed for correct use, and then shows the calculation set up in a spreadsheet with worked field data. Examples are chosen from straightforward oil and gas fields so that the method rather than the complication is the focus. Common mistakes are covered directly, including unit errors, correlations used outside their range and misread pressure data, so that participants learn to check their own work.

Organizations sending participants to this training will:

• Build reliable in-house reservoir engineering capability from the foundation upward
• Bring graduate engineers and cross-discipline staff to a productive technical level faster
• Reduce basic calculation and unit errors in the spreadsheets used for reporting and planning
• Improve the quality of routine volumetric, material balance and forecast work across the asset
• Establish a common technical language between reservoir, production, geology and petrophysics teams
• Prepare staff to progress into advanced reservoir engineering and simulation work.

Participants will:

• Gain a solid working command of the core calculations of reservoir engineering
• Understand what each equation assumes and where it should not be applied
• Build and check their own models instead of relying on results produced elsewhere
• Read pressure and production data and draw the right conclusions from it
• Contribute confidently to field development, reserves and forecasting discussions
• Establish the foundation needed for advanced reservoir engineering study

• Graduate and early-career reservoir engineers
• Petroleum and production engineers moving into reservoir work
• Geologists, geophysicists and petrophysicists working alongside reservoir teams
• Field and operations engineers who need to understand reservoir behaviour
• Reserves and technical evaluation staff building a calculation foundation
• Experienced professionals returning to reservoir engineering after time in another discipline
• Technical supervisors who need to review and understand routine reservoir calculations

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.
