Who Should Attend
Geoscientists and engineers who need to characterize, assess, and manage naturally fractured hydrocarbon reservoirs. Managers and geoscientists who need a basic understanding of the parameters and important features of fractured reservoirs, and/or who need to optimize data-collection workflows for both exploration and production from fractured reservoirs.
Geologists who take this class will acquire an appreciation of the variety of characteristics of natural fractures. They will learn how to look for and measure subtle fracture characteristics in core, and to assess the important but complementary differences between cores and image logs. Students will learn how different types of fractures can affect permeability systems in reservoirs, as well as considerations for assessing the interaction between natural fractures and hydraulic stimulation fractures.
This course is designed to provide the industry geologist and engineer with a working knowledge of fracture characteristics and variability as they affect production in hydrocarbon reservoirs. This is a hands-on, applied course in fracture interpretation, description, analysis, and effects. The two-day course starts with an exercise in which students assess samples of different types of fractured rock and core. We return to these samples half way through the course to show students the salient features that most missed earlier but can now recognize. Other hands-on exercises include assessing fracture strikes in oriented core, assessing fracture distributions and intensities from core data, utilizing our teaching collection of over 50 fracture samples from the outcrop and the subsurface.
Various types of fractures, including regional and structure-related fractures will be discussed, as well as the distributions of fractures in different lithologic and structural settings. The course will also expose students to the characteristics of the most common types of fractures, how to measure and assess fracture populations, and their likely effects on reservoirs. Students will learn to distinguish natural from induced fractures in core, how to determine the reliability of a core-orientation survey, and how reasonable fracture datasets can even be collected from archived, incomplete, un-oriented core. The course includes examples from numerous field and subsurface case studies.
Course outline: Fracture Types and Characteristics; Measurement and Analysis of Fractures in Cores, Logs and Outcrops; Fracture Origins, Mechanics and Predictions; Effects of Fractures in Reservoirs.
