ONLINE: Practical Methods for Mapping and Interpreting Deep-Water Stratigraphy and Reservoirs (GEO953)

  • To be announced

Description

This course is designed to provide participants with a 21st century appreciation of the full spectrum of deep-water clastic stratigraphic successions and their petroleum reservoirs, their mechanisms of transport and deposition, stratigraphic architecture, predictive characteristics and 3D heterogeneity. Based on the full-length classroom version of this course, in the live online session we highlight the range and variability in deep-water depositional systems and examine reservoirs from feeder systems that link the shelf to submarine canyon, submarine fan or distal basin plain, using illustrative outcrop, core and seismic examples from a variety of continental margins.
This course has been re-designed and updated with relevant online content to give industry professionals an understanding of source-to-sink sedimentary transport processes and depositional products, as well as knowledgeable insight into interpretation methods that inform business decisions in exploration, appraisal and development drilling campaigns. This course draws from materials presented in field courses to deep-water sedimentary outcrops and petroleum basins worldwide, and features mapping results from recent and extensive field campaigns primarily in North America, Europe and Asia-Pacific regions.

This course is constructed of 9 modules, each module being its own discipline working synergistically to help participants achieve a high level of understanding of deep-water stratigraphy and reservoirs.

Course Duration: 3 sessions of 4 hours each, delivered over 3 days
Each day will consist of 1 session, split into several modules of 1 hour, followed by a 15 min break. Time will be allowed for questions and discussions.

Course Level: Skill
Instructor: Jon Rotzien

Designed for you, if you are...

  • Seeking technical expertise in mapping and interpreting clastic reservoirs and seals in onshore and offshore regions
  • Seeking understanding of the range of processes and products involved in deep-water sediment transport and deposition
  • Interested in building predictive models for a variety of deep-water clastic environments of deposition (EOD)

How we build your confidence

This course will alternate between inclusive lectures, technical demonstrations, case studies and exercises involving cores, outcrops, logs and seismic data.

The benefits from attending

This course will give you an understanding of how to characterise, map and interpret deep-water clastic depositional systems.
By the end of the course you will be able to:

  • Characterise turbidites, debrites, transitional, slurry- to hybrid-flow type deposits, contourites and reworked deposits and describe their transport and depositional processes, as well as the roles these deposits play in prospective sedimentary basins
  • Map and interpret the different types of deep-water depositional environments (canyon, channel, levee, splay, overbank) and their implications to reservoir architecture and reservoir quality along a variety of passive to active continental margins
  • Integrate seismic, outcrop, core and other industry data to inform decisions in exploration, appraisal and development drilling programs
  • Use modern and ancient depositional systems to provide analogue value for deep-water drilling campaigns
  • Characterise deep-water reservoirs and build relationships with depositional environments using outcrop, core, borehole image logs, FMI and other industry data
  • Understand geologic risk and uncertainty methods in the context of exploration, appraisal and development
  • Use lithofacies and stratigraphic architecture to understand variations in deep-water reservoir properties pertaining to reservoir presence, reservoir quality and seal presence
  • Apply predictive depositional models and first principles to characterise deep-water reservoir properties
  • Conceptualise and apply source-to-sink transport, sequence stratigraphy and other methods to marine and deep-water sediment delivery as well as the role that mass-transport deposits play in creating new exploration opportunities
  • Understand along-slope processes including contour currents that can modify, rework and potentially improve the reservoir quality of turbidite deposits
  • Apply skills in seismic interpretation, reservoir characterisation, core analysis, geophysical log interpretation, sequence stratigraphy, play fairway mapping, geologic risk and uncertainty analysis, gross depositional environment mapping and oil & gas exploration methods

Topics

  • The course starts with an overview of how sediment is transported and deposited from shelf to bathyal depths and focuses on the broad range of sedimentary processes and depositional environments in a variety of passive and active margin settings from around the world
  • Individual exercises involving core and outcrop samples allow participants to describe samples and interpret their mechanism of deposition and their range of possible depositional environments and reservoir properties
  • Next, a deeper dive into depositional environments illustrates the types of reservoir facies, as well as depositional and stratigraphic architecture, likely to be found along the axis and periphery of deep-water depositional systems from submarine canyon head to basin plain
  • Exercises involving core, outcrop and seismic examples highlight the range of deep-water depositional environments and their effect on reservoir architecture and development
  • The skills of core description and integration, reservoir characterisation and sequence stratigraphy are emphasised
  • Core-log-seismic exercises will show modern techniques on how to predict vertical and lateral variations in reservoir architecture in deep-water depositional systems from regions including Western Europe, Asia-Pacific, North America and the Atlantic margins
  • The course will conclude with a summary discussion of the realistic expectations in clastic petroleum reservoirs, as well as new field- and lab-based research that is changing these paradigms. In this section, we will apply critical thinking skills involving modern case studies to interpret geologic outcomes in exploration and development scenarios. Modern advancements in the prediction of sedimentary deposits, facies and reservoir development in a variety of different settings - including examples from rift to drift phases of passive margin development, ponded slopes, above-grade to graded slopes, stepped slopes, foreland, forearc, strike-slip, intracratonic and hybrid basins illustrating various degrees of confinement - will be discussed
