Fractured Reservoir Modeling with application on Fractured Basement Course
Introduction:
This course provides a unique opportunity to learn all the aspects related to the understanding and modeling of fractured reservoirs. Participants will gain knowledge of how fractured reservoirs differ from conventional reservoirs, and how to approach their fractured reservoir projects in a systematic manner. The workshop covers all the aspects of modeling fractured reservoirs. Emphasis will be given to basement reservoirs and their characteristic. This short course will provide attendees with an extensive understanding of concepts, techniques, and methodologies to characterize natural fractures utilizing image logs, core samples, and thin sections. Participants will become familiar with techniques used to identify and measure fracture attributes and kinematic data which are the basis of structural digenetic studies. This information is critical to determine conductive fracture sets which are in turn utilized for calibrating fractures on other scales, including at seismic scale. Issues such as geologic controls on fracturing, classifications of naturally fractured reservoirs, 3D modeling of fractures, and utilization of fracture data to build up static-dynamic models will be discussed. This course also includes applications of natural fracture studies to define locations of exploratory wells and their importance in diverse activities such as field development, drilling direction, and enhanced oil recovery.
Course Objectives:
- Understand: all geological and seismic aspects related to modeling fractured reservoirs
- Analyze: the characteristics of basement fractured reservoirs
- Generate: actual reservoir models from a real case study data set
- Integrate: geology, geophysics, and reservoir engineering concepts in application to a sound reservoir model for complex fractured reservoirs and basement
- Overcome: the challenges in modeling fractured reservoirs through the use of post-stack narrow azimuth seismic
- Identify: fractures and model their density and orientation
- Recognize: productive zones, plan wells, and create fracture porosity and permeability models for reservoir simulation
- To study the key elements to characterize and computer modeling of fractured reservoirs.
- On completion of the course, participants will be able to:
- Define different types of fracturing.
- identify fractures with different data (drilling, logs, and well-tests).
- choose a model to account for fracturing in a reservoir.
Who Should Attend?
The course is designed for those who deal with fractured reservoirs and those who need to develop them using all types of available data. The course will be very useful to all geoscientists involved in clastics, carbonates, and shale plays where fractures play a major role, such as:
- Geophysicists
- Geologists & Geoscientists
- Reservoir Engineers
- Geomodellers
