Description
Central Wyoming provides one of the best natural laboratories to observe analogs for numerous reservoir types and contains world-class exposures of naturally fractured reservoirs. On this trip, participants will observe key reservoirs that produce hydrocarbons in the Rocky Mountain region. The trip is designed for integrated teams of geoscientists and engineers to visualize and actively discuss key reservoir elements. Each location and stop highlights significant issues or heterogeneities and provides talking points for integrated teams to better appreciate the challenges the observed features present to hydrocarbon development.
Learning Outcomes
· Baseline terminology and understanding for key geologic elements to improve communication between disciplines
· Interactive team discussions for each field trip stop emphasizing reservoir elements and challenges being viewed
· Observe world-class analogs for key reservoir elements in Rocky Mountain reservoirs
· Learn the value of conceptual models for populating reservoir models and appreciate the complexities of heterogeneous reservoirs
Course Content
Day 0: Arrival, Safety and Course Overview
Overnight Hilton Garden Inn Casper: 1150 Poplar St., Casper WY 82601
Day 1 (AM): Geologic Background and Introduction of Heterogeneous Reservoirs
Meet: Hotel Meeting Room
· Where are we and why are we here?
· Heterogeneous conventional reservoirs – key elements that impact development
o Aeolian reservoirs (e.g., Weber, Tensleep, Nugget)
o Fluvial reservoirs (e.g., Dakota, Frontier, Fort Union and Lance)
o Carbonate reservoirs (e.g., Madison, Bighorn)
· Fractured Reservoirs – key elements and distinguishing features that impact development
o Fractured reservoir types – Type 1, 2, and 3
o Naturally fractured reservoirs
§ Definitions and terminology
§ Relationship between fractures and structural domains
§ Impact of fractures on reservoir permeability
o Mechanical stratigraphy and the relationship to fracture development
o Fractures within a mechanical stratigraphic framework: Examples from logs, core and outcrop
o Structural styles of the Rocky Mountains
Day 1 (PM): Field Excursion: Casper Mountain (PM)
· Regional overview of and Rocky Mountain structural deformation
· “Bottom up” view of heterogeneous structural deformation
· Inherited structures and regional shear zones related to Precambrian features
· Emigrant Gap Anticline and the intersection of structural domains
Day 2 (All Day): Alcova Reservoir and Fremont Canyon Field Excursion
This field day will combine light hiking to overview locations and visiting specific reservoir elements using pontoon boats on Alcova Reservoir
· Fractured Precambrian basement
· Ordovician Bighorn Dolomite
· Mississippian Madison Limestone Reservoir and Paleokarst system
· Undeformed Pennsylvanian Tensleep aeolian sandstone reservoir (Weber equivalent)
· Anticlinal structure deformation of Tensleep at Alcova Dam area
Presentation of key elements and discussion of heterogeneous reservoir elements will be a critical aspect of this day.
Day 3 (All Day): Alcova Area and Oil Mountain
This field day will combine hiking to overview locations and visiting specific reservoir elements of units listed below:
· Alcova – various localities -heterolithic folding and faulting of Triassic Alcova Limestone and Cret. Cloverly Fm (Dakota equivalent)
· Alcova – fractures of Cret. Mowry Shale
· Oil Mountain – structural domains and fracture development in the Cret. Frontier and Cloverly
Presentation of key elements and discussion of heterogeneous reservoir elements will be a critical aspect of this day.
Day 4 (AM): Wrap-up, Summary and Key Elements Discussion (1.5-2 hrs)
Meet: Hotel Meeting Room
Day 4 (PM): PM Flight Return to Houston
