Content

The evaluation of shale reservoirs presents a unique challenge: whereas some of the approaches applied are the same as for conventional reservoirs, many new methodologies and tools have been developed for the assessment of this unconventional resource. In this classroom seminar, participants are exposed to the latest concepts of mudrock sedimentation and how it relates to reservoir properties. The development of mudrock successions, including depositional processes and stratigraphic cycles, is highlighted.

One key aspect of the course is providing practical techniques for assessing reservoir heterogeneity during play reconnaissance (“data mining”) and regional evaluation (“sweet spot” mapping). Another major goal is interpreting and correlating well-logs within a sequence-stratigraphic framework; lectures are supplemented by a hands-on workshop. In addition, participants will learn what components are fundamental to core description and interpretation, including observations on composition, texture, sedimentary structures, and fractures. A final goal of the class is developing an understanding of the factors that control reservoir quality: mineralogy, lithologic components, cements, fabric, fractures, and pore systems. Methods used to investigate these rock properties also will be discussed. 

Participants will learn to:

  • Determine the key geologic parameters that affect the attributes of shale reservoirs
  • Identify the components of basin analysis required when scoping a new shale play
  • Integrate a variety of data types necessary to identify and map optimum drilling locations and targets
  • Evaluate the variety of depositional processes and changes in environmental conditions recorded in a shale succession and tie that information back to well-log character
  • Assess the basic stratigraphic framework of shale reservoirs and understand how systematic vertical changes relate to fabric, composition, texture, and, ultimately, reservoir quality
  • Interpret and correlate well-logs utilizing a sequence stratigraphic framework
  • Understand the observations and methodology necessary when describing and interpreting mudrock cores
  • Define the key rock parameters that control reservoir quality and mechanical properties
  • Describe the latest methodologies of pore-scale imaging for shale evaluation

Who Should Attend

All subsurface professionals involved in the evaluation of unconventional resources. Geologists, geophysicists, petrophysicists and engineers who want to understand mudrock deposition relative to reservoir properties will benefit from the concepts and techniques presented.

Prerequisites

Participants should have a basic familiarity with resource plays. Some understanding of depositional processes and sequence stratigraphy is recommended.

Bio:

Jeff received his B.A. in Geology from Earlham College, M.S. in Geology from Duke University, and Ph.D. in Geology from Rice University. He has worked in the oil and gas industry for over 35 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 beginning in 2001, first as Chief Stratigrapher and then as Chief Geologist, until his retirement in 2011. In addition, he recently became an Affiliate Faculty member in the Department of Geology and Geological Engineering at Colorado School of Mines.

 Jeff has conducted sedimentologic, sequence stratigraphic, and seismic stratigraphic projects on 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, sequence stratigraphy, and mudrock deposition and stratigraphy, most notably for the American Association of Petroleum Geologists, the Petroleum Technology Transfer Council, Nautilus Worldwide, many oil and gas companies, and universities. His publications encompass numerous papers and abstracts on deep-water sandstones, sequence stratigraphy, geophysical interpretation, and mudrock deposition. Jeff has twice been presented the best luncheon speaker award by the Rocky Mountain Association of Geologists, was presented the Frank Kottlowski award for best speaker in the Energy Minerals Division at the AAPG annual convention in 2012, completed an AAPG Distinguished Lecture tour, and received the Outstanding Scientist Award from RMAG (shared with Donna Anderson) in 2017.
