Fractured Reservoirs: From Geologic Concepts To Reservoir Models

24-28 August 2015
Casper, Wyoming, United States
Who Should Attend
Geologists, geophysicists, reservoir engineers, and geomodellers who deal with fractured reservoirs and 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.

The short course provides a unique opportunity to learn all the aspects related to the understanding and modeling of fractured reservoirs. The unique feature of this course is the ability to take the geologic concepts and use them in reservoir modeling. Hands-on sessions are devoted to the examination of outcrop, core and log data and using that information and a software to create 3D fractured reservoir models. 

The first part of the workshop covers the geologic aspects which allow the geoscientist to recognize different types of fractures from outcrop, cores and boreholes. Once the fractures are recognized, their impact on the reservoir and its performance is examined. 

Six case studies are used to illustrate all the geologic concepts. The second part of the workshop covers all the aspects of modeling fractured reservoirs. Using modeling software and actual data from Teapot Dome, (WY), the geoscientist will be able to construct fracture models that integrate geology, geophysics and reservoir engineering. Emphasis will be given to the critical use of seismic attributes derived from inversion, volumetric curvature and spectral imaging. 

Using actual Teapot Dome field data from the Tensleep and Niobrara Shale formations and a hands-on approach, the workshop allows the geoscientist to identify fractures and to construct predictive 3D fracture models that can be used to identify productive zones, plan wells and to create fracture porosity and permeability models for reservoir simulation.

Prior to starting the modeling exercises, a field trip to the Tensleep outcrop around Casper (WY) will provide to the students the unique opportunity to see the large scale features related to fractures.

The student can take the concepts learned in this class and use them to solve his own fractured reservoirs problems.

Participants are encouraged to bring their laptop computers in order to run the various exercises on their computers during the course.
