Reservoir Engineering for Other Disciplines

Wim Swinkels 
5 Days

Business context

In the E&P business, Reservoir Engineers play a key role in handling, analysing and interpreting subsurface and production data at all stages of field development. Reservoir Engineering data and models are used in field development plans to optimise economic production of hydrocarbons. 

In this course fundamental concepts and a broad spectrum of modern practical reservoir engineering methods are addressed. Extensive use is made of practical and actual field problems to illustrate relevant subjects.

Who should attend

This course is applicable for professionals with prior technical or engineering exposure to exploration and production activities. Targeted participants include new Reservoir Engineers, Production Engineers, Petrophysicists and Geoscientists involved with exploration and development of oil & gas reservoirs.

The course is also useful for Petroleum Engineering team leaders, IT staff and support staff working with reservoir engineering, development and production departments.

Course content

  • Reservoir rock properties.
  • Capillary pressures, surface tension, wettability.
  • Distribution of hydrocarbon fluids, pressure regimes, fluid gradients and contacts
  • Hydrocarbons-in-place estimation,
  • Reserves and resources estimation methods.
  • Fluid properties and phase behaviour,  PVT parameters, fluid sampling
  • Recovery drive-energy, material balance, recovery factors and production forecasts.
  • Gas reservoir engineering concepts.
  • Radial flow equation and well behaviour
  • Skin: source and how to minimize it.
  • Well testing, pressure tests: drawdown and build-up.
  • Reservoir modeling
  • Production forecasting
  • Relative permeability, movable oil, fluid displacement,  mobility,
  • Reservoir heterogeneity and sweep.
  • EOR principles
  • Field Development Planning

Learning, methods and tools

At the end of the course, participants will understand the physics of oil and gas fields, and have an awareness of modern reservoir engineering principles and practices for reservoir development and production, including the estimation of oil and gas reserves.

Topics are introduced by lectures and discussion, and learning is re-inforced by practical small classroom exercises. Active participation is encouraged. Hand-out material in paper and/or electronic format will be provided.  Use of laptops and other handheld devices for the exercises is encouraged and facilitated.

A short test or quiz can be held at the end the course.
