Deepwater Reservoirs – Exploration Risking and Development Characterisation
Participants will learn how to interpret and map environments of deposition (EoD’s) in deep water systems, and understand how the different EoD’s and sub-EoD’s behave as reservoirs. Engineering data will also be used to demonstrate how to improve prediction of reservoir performance.
Business Impact: Through a multidisciplinary approach, this course has a strong business focus in defining mapping strategies to de-risk reservoir presence and to predict reservoir N:G pre-drill. The course highlights the importance of accurate environments of deposition mapping from exploration to production business scales, emphasizing the key architectural archetypes and their impact in predicting baffles and barriers, as well as the distribution of porosity and permeability in the reservoir.
Schedule
Duration and Training Method
This is a classroom or virtual classroom course comprising lectures, exercises, and observations from core, well logs, and seismic profiles.
Course Overview
Learning Outcomes
Participants will learn to:
- Employ interpretation and mapping techniques for cores, well-logs and seismic lines in DW settings from exploration to production business scales.
- Interpret trap configurations and analyze risk for DW stratigraphic traps.
- Analyze reservoir presence risk and Net:Gross prediction.
- Interpret unconventional resources in DW settings, including examples from the Permian Basin.
- Implement sequence stratigraphy and seismic stratigraphic techniques.
- Interpret environments of deposition (EoD’s) and related reservoir architecture, lithofacies associations and diversity.
- Describe the different EoD’s in deep water that can generate reservoir-scale, sand-rich systems.
- Identify the different EoD’s and sub-EoD’s in seismic, well logs, cores and outcrops.
- Analyze reservoir geometry and connectivity in different EoD’s, integrating with production data.
- Review deep water lithofacies and nomenclature, common lithofacies associations and interpret lithofacies in cores.
Course Content
Well-logs and seismic examples will be used as a comparison to core information to help participants link 1-D information to 3-D views of reservoir-scale depositional systems. This class will also review the evolution of concepts in deep water models, emphasizing recent approaches that integrate experimental and numerical models, Quaternary analogues and ultra-high-resolution seismic data.
