Summary

This multidiscipline course demonstrates how deepwater stratigraphic prediction is possible by understanding the distribution of sedimentary attributes within a temporal and spatial framework. The continuous shelf-to- basin exposures of the Brushy Canyon Formation enable time-stratigraphic correlation of variations in sedimentary patterns to their position in a longitudinal depositional profile. Lessons learned from this dataset are considered applicable to all deepwater systems.

Dr. Gardner directed a multidisciplinary team during the Slope and Basin Consortium Modeling Project (2002-2005), which converted 55% of the Brushy Canyon outcrop into high-resolution, geo-referenced geocellular models of Permian deepwater architecture. The applied research, from this project, focused on identifying and interrogating the multivariate geological parameters necessary and sufficient to reproduce and predict common and repeatable deepwater reservoir patterns. Subsurface workflows, best practices and geological rules developed from this research and featured in the course will assist the participants in the identification of new plays and prospects, reducing risk and adding reserves.

Duration and Training Method

A six-day course comprised of field work (85%) and classroom lectures (15%). Almost every field stop includes exercises that illustrate and reinforce the key concepts and methods discussed in lectures and documented in the course notes.

Participants will learn to:

  1. Characterize source-to-sink controls on deepwater systems.
  2. Evaluate the stratigraphic evolution of lithology and thickness distributions in deepwater systems.
  3. Predict stratigraphic modulation of deepwater reservoir architecture.
  4. Assess sedimentary patterns that form different reservoir types and change systematically along the longitudinal profile of deep-marine systems.
  5. Evaluate the role of seafloor topography on deep-marine sedimentary patterns.
  6. Select methods in stratigraphic correlation of deep-marine systems.
  7. Characterize the significance of turbidite event beds and component process facies.
  8. Validate the techniques for retention of geologic data in reservoir modeling.
  9. Propose the optimal workflow for subsurface interpretation of different scales of deep-marine geologic data.

The seismic-scale outcrops of the Brushy Canyon Formation and associated Permian strata provide continuous exposures across a deep-marine longitudinal profile from submarine canyons incised into a carbonate shelf margin, to weakly confined distributive, fan fringe sandstones that thin and pinch out onto a basin margin far removed from siliciclastic sediment sources. Stratigraphic correlations and mapping across multiple cliff faces provide unprecedented documentation of sedimentary architecture in three dimensions. This field course focuses on exposures that illustrate the nature of deep-marine slope and basin-floor reservoir architecture in a fine-grained, sand- rich system.

Overall themes focus on sharpening the tools needed for subsurface prediction of deep-marine reservoir presence and architecture. The course illustrates how a hierarchy of sedimentary attributes, used to define reservoir-scale patterns, correlates to formative processes operating at different temporal and spatial scales (e.g., subaqueous flow velocity, event magnitude, state of flow confinement, and local and regional gradient). The Brushy Canyon outcrops provide uncommon control on the correlation of channel type, profile position, and sediment composition to gradient and flow-scale processes within a stratigraphic hierarchy of deep-marine episodes mapped across a basin.

The first two field days focus on distributive channel and lobe architecture on the basin floor in a fan fringe setting. Outcrops in the southern Delaware Mountains expose deposits that are the most distant from their sediment source. The conformable stratigraphy and widespread sand distribution here conspicuously contrasts with the disconformable patterns exposed in outcrops along the northwestern basin margin.

The following three field days examine submarine canyon and deep-marine slope strata along the spectacular kilometer high outcrops of the Western Escarpment of the Guadalupe Mountains. The evolution from an inherited carbonate ramp, incised by submarine canyons, to depositional outbuilding of a siliciclastic slope records the change from under- to over-filled conditions across slope channel fairway and interfairway regions. The architecture of multistory channels, as well as, the fill of intraslope depressions is correlated to stratigraphic modulation of under- and over-supplied conditions describing the relationship between subaqueous flow size and the size of the receiving basin. The continuous exposures permit stratigraphic correlation of time-significant surfaces, on the higher gradient slope, to time-equivalent strata on the lower gradient basin floor. These surface-to-rock correlations are illustrated in seismic models and detailed three-dimensional reservoir models of the outcrop, which form the basis for field exercises that reinforce important conceptual models and methods in hierarchical sedimentary geology.

Who should attend

N302 is essential for reservoir engineers, development geologists, geophysicists, petrophysicists, geocellular modelers and team managers involved in the maintenance and development of conventional and unconventional deepwater reservoirs and wish to broaden and deepen their knowledge of deep marine clastic plays.

Prerequisites and linking courses

Participants should understand the fundamental processes and terminology of sedimentology before attending the class. This can be gained on Basic Application Level courses N155 (Introduction to Clastic Depositional Systems: a Petroleum Perspective) and N156 (Clastic Depositional Systems in a Basinal Framework: Exploration and Reservoir Implications, Pyrenees, Spain).

Several other field and classroom courses address deepwater clastic systems at Skilled Application Level, including N009 (Sedimentology, Stratigraphy and Reservoir Geology of Deepwater Clastic Systems, County Clare, Ireland). Those interested in understanding the influence of structural controls on deepwater clastic systems may wish to attend N028 (Sand-rich Turbidite Systems and Megaturbidites: From Slope to Basin Plain. Facies, Stacking Patterns and Controlling Factors, Pyrenees, Spain).  N033 (Characterisation, Modelling, Simulation and Development Planning in Deepwater Clastic Reservoirs, Tabernas, Spain) focuses on modeling and development planning in deepwater systems. The N442 filed course (Reservoir Architecture of Deep Water Systems, in California) focuses on the role of submarine channels and fans in deepwater sedimentation. The common deepwater architectural elements of the Pennsylvanian-age Jackfork Group are examined in N292 (Deepwater Depositional System Stratigraphy for Exploration and Development; Arkansas, USA).

The physical demands for this class are HIGH according to the Nautilus Training Alliance field course grading system. Participants should anticipate long field days with an average of 10-12 hours away from lodging facilities. Attendees must be prepared for long (3-6 km; 2-4 mile) hikes across rough and sometimes steep terrain. The five field days will involve long traverses away from the vehicles. The field area is at an elevation of approximately 1500 m (5000 ft). This fairly high elevation in combination with hot temperatures and dusty conditions may lead to unexpected fatigue or shortness of breath for some participants. In order to gain the full benefit of this class, participants should be fit enough to complete these hikes under these conditions.

Transport on the course will be by SUVs. Most of the driving is on black-top roads, with some driving on graded dirt roads. Two days include long 17 mile off-road track driving on rough, rocky trails.

Background
Michael (“Mike“) Gardner is the founder of Get Smart Geoscience, a private educational and research enterprise dedicated to the advancement of sedimentary geology through outcrop analog studies for subsurface solutions. Get Smart Geoscience offers on-site and field-training courses on the application of sedimentary geology to the prediction of reservoir presence and architecture. Mike’s geoscience training courses build on 100 field courses and 32 university Courses Taught for RPS Nautilus in 25 years of industry-sponsored academic research. Mike has held faculty and research positions at Montana State University at Bozeman (2005-2015), the Colorado School of Mines (1995-2005), and the Bureau of Economic Geology at The University of Texas at Austin (1990-1994). He has authored 190 papers, abstracts, and guidebooks and supervised 26 MS and PhD theses.

Mike Gardner’s research interests include developing methodology for hierarchical analysis of sedimentary geology through the integration of tectonic, stratigraphic and sedimentologic systems. The development and application of conceptual models, linked to explanatory rules, are emphasized in this approach to subsurface interpretation of sedimentary geology. Building on the highly regarded, decade-long study of the Permian deep-marine strata in West Texas, Mike initiated the industry-sponsored Geological Analogs and Information Archive (GAIA) project (2007-present) for the worldwide study of deep-marine outcrops analogs documented in ongoing field studies in Baja California, Mexico, California, Oregon, Utah, Colorado, Wyoming, France, Italy, Spain, Java Indonesia, and New Zealand and supplemented with the published literature.

Mike is a committed field geologist interested in posterity through the development on cyber-information technology that maximizes the value of sedimentary geology from outcrops. The GAIA project development of the Deepwater Knowledge Base and the Deepwater Expert System provides novel, internet-hosted and GIS-enabled tools designed for easy integration of outcrop analog data in subsurface workflows. Geo-spatial pattern recognition software and content management systems guide evaluation and selection of analog data correlated to conceptual models and explanatory rules developed to supplement subsurface analysis. These cybernetic tools enable both empirical and conceptual application of analog data, with key findings incorporated into more general training courses like this one. Mike advices, teaches and conducts Phase III of the GAIA Project for the Slope and Basin Consortium from Bozeman, Montana.
