Women in Energy Field Experience: The Role of Salt in Hydrocarbon Exploitation, Energy Storage and Carbon-reduction Mechanisms, Paradox Basin, Utah and Colorado (G084)

Tutor(s)

Kate Giles: Lloyd A. Nelson Professor, University of Texas at El Paso; Consulting Geologist.

Cindy Yeilding: NE Director, Denbury Inc.

Overview

This course is aimed exclusively at women working in the energy industry, particularly in the geoscience, geotechnical and engineering fields. The primary technical goal is to provide a widely applicable introduction to the interrelationship between sedimentation and structural geology with a particular focus on salt tectonics and salt-sediment interaction. The geology is examined with reference to energy production, including hydrocarbon exploration and production, along with discussions around energy transition topics (CCUS, geothermal, hydrogen and energy storage). While the technical aspects are paramount, the course is also designed to provide networking and professional development opportunities. Evening discussions and activities will allow for exchange of ideas and experiences in a supportive and open atmosphere.

Duration and Logistics

A 5-day field course starting and finishing in Grand Junction, Colorado, comprising a mixture of field exercises, activities and networking.

Level and Audience

Fundamental. This course requires a basic understanding of geoscience and will suit those working in the geoscience, geotechnical and engineering fields. The aim is to facilitate knowledge and experience exchange among the participants, so is open to women from a very wide range of experience levels.

Exertion Level

This course requires a MODERATE exertion level. There will be hikes to outcrops of up to 6.5km (4 miles) round trip. Some of these will encounter uneven and rocky ground with some short, steep inclines. The climate in southern Utah is typically warm to hot and dry with temperatures up to 37.5°C (100°F) and the elevation is between 1,250–1,500m (4,000–5,000 ft).

Objectives

You will learn to:

  1. Describe the regional stratigraphy and principal structural features of the Paradox Basin, Utah.
  2. Characterize and interpret controls on Paradox Basin salt-related structures and key features of passive diapiric systems, including halokinetic sequences, caprock development, non-evaporite stringers / inclusions, welds, megaflaps, counter-regional faults, radial faults and burial wedges.
  3. Examine stratal geometries and halokinetic sequences and how these relate to intervals of salt inflation / evacuation and sediment flux.
  4. Assess the controls on basin fill architecture, fluid flow and deformation within the Paradox Basin and compare this to analogous salt basins worldwide.
  5. Understand the importance of salt basins to the energy industry for hydrocarbon production.

Reservoir Geology for Engineers, Colorado and Utah (G061)

Tutor(s)

Mike Boyles: Retired Shell Oil; Affiliate Faculty, Colorado School of Mines.

Overview

The course investigates world-class outcrops to introduce engineers to a wide spectrum of stratigraphic and structural features commonly found in exploration and production. An active learning technique encourages participants to make initial observations and interpretations before group discussions. Lectures and exercises provide awareness of reservoir architecture while outcrops demonstrate field- and reservoir-scale heterogeneities. Depositional environments studied include deltaic, eolian, fluvial, turbidites, tidal and coastal plain with emphasis placed on understanding flow characteristics (i.e. connectivity, Kv, Kv/Kh).

Duration and Logistics

7 days; a mix of classroom lectures (10%) and field exercises (90%). The course begins and ends in Grand Junction, Colorado, and visits outcrops in Utah and Colorado.

Level and Audience

Fundamental. The material is presented with minimal jargon so that engineers get the full benefit of the course.

Exertion Level

This class requires a MODERATE exertion level. Scrambling over rock outcrops and steep sections will be required, but most hikes would be considered moderate. The longest walk is approximately 4.8km (3.2 miles). Outcrops are at elevations of 1200–2500m (4000–8200 ft). Weather conditions in NW Colorado and eastern Utah can vary from warm and dry to cold and wet, with an early fall temperature range of 5–23°C (41–73°F). Transport will be in SUVs on black-top and unpaved roads.

Objectives

You will learn to:

  1. Appreciate the differences between a range of depositional settings, their facies and related reservoir architecture.
  2. Use geologic knowledge to reduce reservoirs into flow units.
  3. Gain a better understanding of major events that influence deposition and help to understand reservoir geometries and scale.
  4. Evaluate the impact of modeling stochastic properties versus organized trends.
  5. Understand the dangers of upscaling and if it makes geologic sense.
  6. Use detailed sector models to understand how to capture subtle variations in the geology.
  7. Appreciate how to use the geology to make upscaling decisions by building detailed sector models to understand the impact of upscaling decisions.

Shoreline and Shelf Reservoir Systems, Colorado (G013)

Tutor(s)

Mike Boyles: Retired Shell Oil; Affiliate Faculty, Colorado School of Mines.

Overview

This course contrasts two very different clastic shoreline systems by studying two sets of outcrops that were deposited at approximately the same time, about 100km (62 miles) away from each other. One set was deposited by classic river-feed, wave dominated delta systems and the other set had depositional strike-feed systems. The wave dominated deltas are common reservoirs in many basins. However, the less common strike-feed systems have a very different stratal architecture, which can result in the development of significant stratigraphic traps. Participants will develop competence in understanding clastic shoreline and shelf systems and applying sedimentology and sequence stratigraphic concepts to build depositional models and predict facies distributions.

Duration and Logistics

A 8-day field trip comprising a mix of classroom lectures (10%) and field time (lectures and exercises 90%). The course begins in Craig, Colorado, and ends in Steamboat, Colorado. Participants fly in and out of Hayden, Colorado.

Level and Audience

Advanced. Geologists, geophysicists and reservoir engineers working on fluvial / deltaic exploration and production projects. This course is especially relevant for people working reservoirs that were deposited under a tidal influence. The material is presented with minimal jargon so that reservoir engineers can get the maximum benefit of the material.

Exertion Level

This class requires a MODERATE exertion level. Scrambling over rock outcrops and steep sections will be required, but most hikes would be considered moderate. The longest hike is approximately 3.2km (2 miles). Outcrops are at elevations of 1300–2000m (3900–6000 ft). Weather conditions in NW Colorado can vary from warm and dry to cold and wet, with an early fall temperature range of 6–25°C (42–78°F). Transport will be in SUVs on paved and unpaved roads.

Objectives

You will learn to:

  1. Evaluate facies associated with wave dominated deltas, tidal shelf deposits and the often-under-recognized strike-fed tidally influenced shoreline deposits.
  2. Compare depositional dip and strike facies variations within a wave dominated delta complex at the regional scale.
  3. Distinguish deltaic distributaries from incised valley deposits associated with an unconformity.
  4. Identify facies and subsurface geometries of isolated, tidally dominated shelf reservoirs and understand possible links to older shoreline deposits and processes that controlled genesis of these stratigraphic traps.
  5. Use sequence stratigraphic principles to distinguish sequence boundaries, flooding surfaces, transgressive surfaces of erosion and maximum flooding surfaces.
  6. Begin to use the concepts of shoreline stacking patterns to better predict lateral continuity of shoreline systems.
  7. Make interpretations of reservoir systems from subsurface data based on the techniques practiced in the field.
