Fractures, Folds, and Faults in Thrusted Terrains: Sawtooth Range, Montana

Considered to be one of the most complex geological systems and technically challenging environments for exploration and production, folds and thrust belts, require a well prepared and executed exploration strategy. Understanding how these systems work along with the increasing advances in seismic imaging, structural modelling and fracture characteristics will help mitigate the issues and risks of exploration and production of hydrocarbons in these regions. This field seminar will allow participants the opportunity to learn and discover more of the geology, geophysics and many other aspects that are involved in E&P in thrust belts. Lead by several instructors with decades of expertise working in thrust belts around the world, the field seminar will offer first hand experience and insights of these terrains. The focus will be on the practical issues of E&P of hydrocarbons in trust belts, with the Montana Thrust Belt as reference. Knowledge and information gained will allow participants to apply these concepts worldwide across other targeted thrust belts. Join us September 8-13 in Great Fall, Montana.

Who Should Attend

Exploration and development geologists, geophysicists, log analysts, engineers, and managers working in structural geology and/or fractures who want a thorough understanding of the geology and geophysics utilized in E&P in thrust belts.

Objectives
Upon completion of this field seminar, participants will be able to:

  • Identify natural fractures and discuss analogs.
  • Differentiate natural vs. induced fractures.
  • Make connections between structure & fractures & prolific oil fields in the region and new discovery potential.
  • Have a greater understanding source rock petroleum systems of a thrust belt, and its influence on adjacent forebulge resource oil plays.
  • Develop completion programs where fractures and structure play a major role in the reservoir.

Course Content
During this seminar, leaders and attendees together will:

  • Examine the mechanics of fracturing, folding, and faulting in thrust belt terrains.
  • Identify and discuss new ideas regarding the geometry and kinematics of the development of thrust belts with examples from the spectacular Sawtooth Range of northwest Montana.
  • Compare seismic interpretation with outcrop examples and review drilling practices in a “frontier” (Montana) exploration thrust belt province.
  • Analyze stratigraphic concepts which are essential in the exploration of thrust belt targets.

This field seminar is unique in that it offers the participant the opportunity to interact with a number of instructors who have several decades of experience working in thrust belts of the world. It focuses on the practical issues of exploration and production of hydrocarbons in thrust belts, with the Montana Thrust Belt as the backdrop. It will explain how these concepts can be applied worldwide, where overthrust terrains are increasingly important exploration targets.

The course will integrate concepts of exploration, including a review of fractured reservoir models, structural geology, stratigraphy, and hydrocarbon assessment. The spectacular geology of the Montana Sawtooth Range (an exhumed duplex) will serve as the backdrop for this field seminar. Time in the field will be bolstered by periodic classroom sessions on structural geology concepts, fractured reservoirs, and other issues the explorationist can expect to encounter in thrust belt exploration.

The seminar will utilize traverses to examine multiple thrust sheets exposed in Sun River Canyon, the famous Teton Anticline, and an outstanding example of an exposed fractured reservoir along a fault propagated fold in Mississippian carbonates as Swift Reservoir. Discussions will involve new ideas on the geometry and kinematics of thrust sheets and how they might influence exploration strategies in those settings.

Participants will discuss the Bakken/Exshaw petroleum system of the Montana Disturbed Belt, and its influence on the emerging resource oil play on the adjacent Sweetgrass Arch. The seminar will continue northward to Glacier National Park, with a cross-section view of the Lewis Thrust, the Chief Mountain klippe, discussions of horizontal Bakken oil drilling on the nearby Blackfeet Indian Reservation and the historical giant gas field production across the border in Alberta, and conclude with a geologic transect along the scenic Going-to-the-Sun Highway of Glacier National Park.
