Introduction

Carbonate and clastic reservoirs are characterized by significant heterogeneity at numerous scales, ranging from exploration to production and enhanced production scale. Understanding of how primary depositional facies, diagenesis, and the sequence stratigraphic framework control the development of pores in carbonate and clastic rocks, and how the variation in pore architecture influences reservoir porosity and permeability characteristics is a fundamental step in the accurate reservoir characterization of carbonate and clastic units. With the ubiquitous use of geostatistical models to define 3D reservoir architecture, it has become increasingly important to accurately define the probable geometric distribution of potential reservoir facies, fluid barriers, and baffles at multiple scales to help build more accurate geologic models that can then be used to manage and improve reservoir development. To effectively do this, the challenge is to integrate data on the primary depositional environment (facies, probable geometry, and susceptibility to diagenetic modification), the sequence stratigraphic framework, and the petrophysical characteristics of carbonates and clastics at multiple scales. This course will review the controls on carbonate and clastic reservoir heterogeneity from the pore architecture scale to the geometrical attributes at reservoir-scale and how these parameters can be incorporated and integrated into the development of viable petrophysically-based reservoir models for carbonates and clastics. In-class exercises are used to reinforce the potential integration of various data sets to provide students with experience in carbonate and clastic reservoir characterization. The comprehensive course documentation has been designed as a useful guide for future reference.

Objective

At the end of the course the Attendees should be able to:

Build on previous experience with carbonate and clastic systems to integrate various aspects of carbonate and clastic rocks (depositional environment, primary facies and mineralogy, high resolution sequence stratigraphy, and various petrophysical characteristics) for improved carbonate and clastic reservoir architecture and flow unit characterization
Apply knowledge of petrophysical, sedimentological petrologic tools to characterize and evaluate carbonate and clastic reservoirs
Recognize and better understand well log responses in carbonate and clastic systems and to learn to utilize data from formation evaluation tools to determine reservoir quality (porosity, permeability, and lithology)
Identify potential stratigraphic variations in carbonate and clastic pore architecture and its effect on permeability
Better understand the relationship of primary depositional facies, sequence stratigraphic framework, and diagenetic history to pore architecture and reservoir quality
Better understand fracturing in carbonates and clastics, relating fracture density, aperture, length to facies, lithology, and diagenesis.
Better understanding for application of well logging to carbonate and clastic reservoirs, characterization and sequence stratigraphy.
To know more about case studies from Oman, e.g. Shuaiba and Buah.
