Petroleum Engineering: Integration of Static and Dynamic Models

by Patrick Corbett

Duration: One to two days

Intended Audience: The integrated nature of this course means that it is suitable for individuals from all subsurface disciplines (geology, geophysics, petrophysics, geomodeling, and reservoir and petroleum engineering). Additionally, the course is very suitable for teams of subsurface staff. Managers are encouraged to attend in order to consider technical and organizational aspects of integrated subsurface teams.

Summary:
This course in designed for a broad range of geoscientists and engineers working in the petroleum industry. The course provides improved linkage between the techniques used at various scales to describe and model petroleum reservoirs. The ultimate objectives are to enable technical staff to maximize the recovery of hydrocarbons. The impact of petrophysical heterogeneity at various scales on the recovery of oil and gas provides the focus for the course.

Course Description:

  • The course introduction shows how petroleum geoengineering concepts have developed along with the requirement for more integrated and synergistic technical teams addressing reservoir development projects.
  • The course emphasizes the links between the stratigraphic controls on geobody architecture (and properties), the connectivity, and the ultimate recovery factors.
  • Petrophysical and rock physics properties are measured at a variety of scales. An exercise will explore how averages can be used to determine effective properties at larger scales.
  • Reservoir models are built by industry using a range of geostatistical techniques, and these require calibration by dynamic measurements at various scales. The role of seismic in modeling is considered at the appropriate stage.
  • Sweep efficiency and recovery factors are determined by scales of lateral and vertical heterogeneity. The use of the Lorenz and Modified Lorenz plots is demonstrated in an exercise to illustrate the importance of internal reservoir architecture in controlling recovery factors.
  • The course challenges subsurface teams to consider strategies for improving oil recovery and, with the high demand and price, to target ever higher recovery factors.
