N251 Well Log Sequence Stratigraphy: Applications to Exploration and Production
N251 Well Log Sequence Stratigraphy: Applications to Exploration and Production
This seminar provides a hands-on, practical approach to the sequence stratigraphic analysis of well logs and its application to well-log correlations. The course is conducted in a workshop format within which participants are introduced to the basic concepts and models of sequence stratigraphy, followed by numerous exercises. The class provides the skills for better prediction, evaluation, and development of reservoirs by geoscientists and engineers.
This is a five-day classroom course that runs in Golden, Colorado, on the campus of Colorado School of Mines. Lectures, discussions, and individual and group exercises introduce participants to the concepts of sequence stratigraphy and develop methodologies for its practical applications. Approximately 25% of the course time is allocated to lectures, 65% to exercises and 10% to core viewing.
Participants will learn to:
Through the integration of lectures and hands-on exercises, attendees first learns the fundamental concepts and terminology of sequence stratigraphy. Participants then build upon this knowledge in the interpretation and correlation of well logs. A key step is the recognition of significant chronostratigraphic surfaces (e.g., sequence boundaries/lowstand surfaces of erosion, marine regressive surfaces of erosion, marine transgressive surfaces of erosion, flooding surfaces, maximum flooding surfaces) as expressed in well logs. These surfaces are then used in constructing numerous log correlation sections for a variety of depositional environments in both siliciclastic and carbonate settings. Such skills allow one to subdivide stratigraphic intervals into meaningful genetic packages, interpret depositional histories, and build geologically accurate maps to enhance exploration and development. Ultimately, participants will develop analytical insights and skills necessary to help identify and predict new prospects, assess drilling targets, and better produce reservoirs.

Course Wrap-Up
Exploration and development geologists who want an introduction to sequence stratigraphy and the ability to create geologically meaningful well-log correlations and maps. Also, geophysicists who routinely construct well-to-seismic ties and integrate their interpretations with the work of geologists, paleontologists, and/ or reservoir engineers. Reservoir engineers and geosteerers will also benefit from the concepts and techniques presented.
An understanding of basic siliciclastic and carbonate depositional settings and facies is strongly recommended, but not mandatory. Familiarity with wireline logs is also highly desirable.
Appropriate courses providing these fundamental concepts include N155 (Introduction to Clastic Depositional Systems: a Petroleum Perspective); N020 (Carbonate Depositional Systems: Reservoir Sedimentology and Diagenesis) and N003 (Geological Interpretation of Well Logs).
For those who desire more advanced training, this course links to many Nautilus Training Alliance courses, including N244 (Clastic Reservoir Prediction Using Advanced Sequence Stratigraphic Interpretation, Wyoming, USA); N011 (High Resolution Sequence Stratigraphy: Reservoir Applications, Utah, USA); N091 (Carbonate Reservoir Architecture and Applied Carbonate Sequence Stratigraphy, West Texas and SE New Mexico, USA); and N059 (Applied Carbonate Geology: Carbonate Facies and Reservoirs, Mallorca and Menorca, Spain).

Background
Jeff has worked in the oil and gas industry for over 30 years: as a research geologist with Marathon Oil Company (1981-1994); as a geological and geophysical consultant with Enron Oil & Gas (1994-1996) and GeoQuest Reservoir Technologies (1996-1998); as an exploration geoscientist with DDD Energy (1998-2001); and with EOG Resources (2001-2011), first as Chief Stratigrapher and most recently as Chief Geologist.
Jeff’s work has entailed sedimentology and sequence stratigraphy from outcrops, cores, and well logs, plus seismic stratigraphic studies of basins and fields worldwide. Areas of expertise include onshore and offshore Gulf of Mexico; onshore and offshore California; Uinta, Green River, Washakie, Denver, Powder River, and Williston Basins; northern and eastern Egypt; and Natuna Sea, Indonesia. At EOG, he provided regional to prospect-scale stratigraphic interpretation and evaluation plus training in support of all divisions. Jeff also conducts a variety of classroom and field seminars on clastic facies, deep-water sandstones, mudrock deposition and stratigraphy, and sequence stratigraphy, most notably for the American Association of Petroleum Geologists, Nautilus, and many universities. In addition, he has published numerous papers and abstracts on deep-water sandstones, sequence stratigraphy, and geophysical interpretation.
