TRAINING - THEORY COURSES


Our public and private training courses help you to get the most out of modern structural analysis techniques. We have designed the courses to meet the challenging and changing demands on the technical skills of geologists and geophysicists as exploration and development moves into more advanced phases. Courses can also be offered in-house at your offices, and can be tailored to your specific day-to-day work requirements.


Fault Seal Analysis - Theory (1 or 2 days):

A one or two day theory-based course on methods and techniques for evaluating sealing faults. The emphasis is placed on the application of an objective methodology to the analysis of sub-surface data (seismic interpretation and wells). The course is suitable for geologists, geophysicists and reservoir engineers.

All sessions comprise a mixture of lectures and practical sessions.
The course is designed to give geologists and reservoir engineers a thorough overview of new structural techniques for detailed analysis of fault seal.

COURSE CONTENTS:

Key Concepts Causes and evaluation of subsurface pressures; seal classification - capillary seals and permeability.

Fault juxtaposition seal Fault-displacement patterns, analysis of seismic interpretations and map data, triangle diagrams.

Fault-seal mechanisms Clay smear, cataclastic features, cementation/diagenesis, prediction of fault-seal capacity (gouge ratio and smear factor)..

Faults, fluid flow and diagenesis Fluid flow along faults, slip tendency.

Fault seals in production Application to reservoir models, estimation of transmissibility multipliers.


Practical Fault Analysis (3 days):

This new course is intended both for new-hires and existing professionals who need to broaden their understanding of the essential elements of structural geology that impact the quality of seismic interpretation.

Practical Fault Analysis covers all aspects of fault interpretation, from picking strategies through correlation and linkage to structural quality control. It comprises a significant amount of theory work supplemented by paper exercises and software-based exercises using T7.

Concepts covered include practical interpretation, visualization, working in 3-D, theoretical aspects of fault development, fault statistics, routine application of theoretical and observation-based quantitative and semi-quantitative rules, derivation of geologically robust faulted frameworks, and how to quality-check fault interpretations and fault-horizon polygons.

COURSE CONTENTS:

Fault Analysis Concepts Good seismic interpretation of faults should include a workflow that checks the interpretation against known structural properties of fault systems. Concepts and methods for the analysis of faults are presented, leading to a geologically-robust interpretation.

Fault Framework Models A geologically robust 3-D Fault Framework model of the faulted sub-surface is a prerequisite for accurate mapping, ultimately leading to optimal well planning and volumetric calculations. Working in a full 3-D modelling environment, easy-to-use techniques are applied to constrain the modelling process, resulting in a geometrically and geologically consistent fault model.

Case studies Case Studies are presented to show the value of implementing these new methods.
