Summary

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. It 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. 

The course emphasizes key changes in deep water reservoir models that have a major impact on exploration and production of these reservoirs. 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.

Duration and Training Method

This is a five-day classroom course comprising lectures, exercises, and observations from core, well logs and seismic profiles.

Course Overview

Participants will learn to:
  1. Employ interpretation and mapping techniques for cores, well-logs and seismic lines in DW settings from exploration to production business scales.
  2. Interpret trap configurations and analyze risk for DW stratigraphic traps.
  3. Analyze reservoir presence risk and Net:Gross prediction.
  4. Interpret unconventional resources in DW settings, including examples from the Permian Basin.
  5. Implement sequence stratigraphy and seismic stratigraphic techniques.
  6. Interpret environments of deposition (EoD’s) and related reservoir architecture, lithofacies associations and diversity.
  7. Describe the different EoD’s in deep water that can generate reservoir-scale, sand-rich systems.
  8. Identify the different EoD’s and sub-EoD’s in seismic, well logs, cores and outcrops.
  9. Analyze reservoir geometry and connectivity in different EoD’s, integrating with production data.
  10. Review deep water lithofacies and nomenclature, common lithofacies associations and interpret lithofacies in cores.

Well-logs and seismic examples will be used as a comparison to core information to help participants link 1-D core 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. The resulting new depositional models will have strong impact from exploration to production scales.

This course is intended for geoscientists, petrophysicists, engineers, and managers who are seeking a comprehensive introduction to deep water reservoir plays. It is appropriate for those with no previous experience with these reservoirs, those that have some experience and wish to broaden their understanding, and more experienced people who want exposure to some of the most recent technologies and practices. It is not intended as an advanced course for individuals with extensive experience working these reservoirs.

Background
Vitor Abreu has 28 years of experience in the oil industry in petroleum exploration, development production and research, with a proven record in evaluating, risking and/or drilling in 22 countries and 31 sedimentary basins in the 6 continents. His areas of expertise include projects in exploration, development and production of deep water reservoirs, regional studies to define the petroleum system elements and key plays in frontier exploration, tectono-stratigraphic evolution of basins in different tectonic settings, maturing opportunities to drillable status, and play to prospect risking assessment. His experience in development and production includes several field studies in different depositional environments, with high-resolution stratigraphic interpretation integrated to engineering data to define reservoir connectivity and main baffles and barriers for effective field development plans. On research, Vitor is considered one of the world leaders on reservoir characterization of deep water systems, proposing new deep water models with strong impact in development and production.

Vitor has been an Adjunct Professor at Rice University since 1999, where he took responsibility for the course on Sequence Stratigraphy after Peter Vail’s retirement. He was the recipient of the Jules Braunstein Memorial Award (best poster presenta-tion, 2002 AAPG Annual Meeting) and was appointed AAPG’s inaugural international Distinguished Instructor in 2006. He is the current President-Elect of SEPM and has been organizing and chairing technical sessions at annual meetings for both AAPG and SEPM. More than 1000 students globally have taken his short course on “Sequence Stratigraphy for Graduate Students” since 2000. This course has been taught at annual meetings, international meetings, universities, and companies around the world. Vitor is the chief editor of SEPM’s “Sequence Stratigraphy of Siliciclastic Systems”, which has sold more than 3000 copies since publication in 2010.
