Clastic Sequence Stratigraphy and Sedimentation

Business context

A good understanding of how depositional processes control the distribution of clastic reservoir and

non-reservoir rocks in the subsurface is of fundamental importance to sound EP decision making. This

applies throughout a field's life-cycle, all the way from the exploration phase, through appraisal, field

development and finally field abandonment.

Who should attend?

Petroleum geoscientists. Petroleum engineers and members of integrated asset teams, who are

responsible for defining and evaluating subsurface geological risks and uncertainties. The course

targets EP professionals in the initial phase of their career.

Course content

Overview of clastic stratigraphic analysis and sequence stratigraphy. Course focuses on how geological

characteristics of a reservoir impact on EP decision making during all phases of a field's life cycle.

Clastic depositional systems &amp ,reservoir characteristics

o Fluviatile systems

o Deltaic systems

o Non-deltaic coastal systems

o Deepwater systems

Sequence stratigraphy

o Controls on sea level changes

o Fundamental concepts terminology

o Fluviatile, deltaic and turbidite systems in a sequence stratigraphic context

Fundamentals of clastic reservoir architecture and subsurface fluid flow

o Clastic reservoir architecture

o Reservoir rock typing

o Recovery mechanisms and subsurface fluid flow

o Static reservoir modelling workflow

Learning, methods and tools

The course uses a combination of lectures and paper exercises. The exercises are mostly built around

correlation problems to highlight the importance of using sound sedimentological and stratigraphic

concepts for building fit-for-purpose subsurface models.

Instructor

Mark Bouman

Mark Bouman studied Geology at Utrecht University (stratigraphy as major, with sedimentology and geochemistry as minors) and graduated in 1981. Directly thereafter he joined Shell where he was subsequently shipped to exotic places like Lima (Peru), London (UK) and Cairo (Egypt). He started off in Peru, in exploration, where he worked as stratigrapher and wellsite geologist during the Camisea drilling campaign. After London (working on mostly Southern North Sea fields) and Egypt (Head of Lab and involved in e.g. the Obaiyed discovery), he returned to Holland where he had the pleasure of teaching Exploration Geology in Shells Training Centre in Noordwijkerhout. He then moved to Production Geology and worked as Team Leader for a number of mainly African fields (Egypt, Algeria, Cameroon, Nigeria). In this capacity he led a team of PG's, SI's, RE's, PT's and WE's with the main task of producing FDP's. After that he moved back to Training, where he, with appropriate passion, taught the secrets of Production Geology to Shell's new recruits.
