Throughout the exploration cycle, from play-based exploration to prospect maturation, from near field exploration to appraisal, a sound geological knowledge of reservoir presence (distribution and geometry) and quality distribution (reservoir effectivity) should underpin the regional and detailed prospect specific mapping, modelling and subsequent risk and volumetrics work.
The 'Predicting Reservoir Distribution, Geometry & Quality' course, aims at improving delegates predictive capabilities of reservoir recognition in terms of type, distribution and quality. Seismic Stratigraphic analysis and Case histories form a key part of the course.
Who should attend
This virtual instructor led training course aims at improving the conceptual geological understanding behind predicting presence and quality distribution of potential reservoirs, starting from seismic and sequence stratigraphic principles. The training material is derived from a variety of geological settings and comprises a mix of petroleum geology case histories and textbook material including seismic, log, core and outcrop data. Focus of the course is on predicting reservoir presence and reservoir effectivity.
Course content
Resolution, dimensionality and integration of different types of geological data.
Key Concepts of Seismic Stratigraphic Analysis: Understand stratigraphic surfaces and hierarchy and Depositional sequences and systems tracts.
PoroPerm systems (reservoir effectivity).
Seismic Stratigraphic and Depositional analysis of Deltaic reservoirs, Clastic Shelf reservoirs, Deep Water reservoirs and Alluvial reservoirs.
Stratigraphic traps.
Correlation do's and don'ts
Seismic Stratigraphy and Correlation Case histories a/o from China, Madagascar, Egypt, NW Borneo, Niger Delta, Spain and the North Sea
Learning, methods and tools
This VILT (Virtual Instructor Led Training) course makes use of live online interfaces.
Learning content is captured in shared presentation and exercise data such as seismic, log, core, outcrop and satellite images.
Method of teaching consists of a mix of lectures and interactive exercises, while stimulating individual, team and plenary discussion.
Each session -after session 1- will start with a recap of the previous session and some informal quiz questions.
Regular home assignments give the delegates the opportunity to deepen / broaden the learnings of the live sessions.
The trainer is available for coaching and answering questions via email outside live session hours.
