Mapping Subsurface Structures


Development geologists and those exploring mature areas; early-career geologists and technologists who make structure maps; those who need to judge the validity of maps and cross sections.


- Contouring techniques
- Triangulation
- Using dip in mapping
- Different measures of thickness and thickness in deviated wells
- Isopach and isocore maps
- Dip-domain cross sections
- Data projection
- Trend and plunge of folds on tangent diagrams
- Composite-surface maps
- Fault shapes and displacement distributions
- Heave and throw from stratigraphic separation and stratigraphic separation from structure contour map
- Constructing fault-plane maps and faults on isopach maps
- Combining fault and horizon maps and contouring across faults
- Structural quality-control techniques
- Multiple-surface map compatibility
- Map validation using implied fault contours
- Finding faults and fault orientations with SCAT analysis of dipmeters
- Juxtaposition diagrams for fault seal analysis
- Fault-cutoff lines in computer mapping
- Soft linked and hard linked faults
- Relay and branching fault patterns
- Mapping sequential cross-cutting faults

Learning Objectives

This course is intended to provide development and early career geologists with a detailed understanding of the theory and techniques used to create structure maps. As well as giving them the ability to judge, QC and validate structure maps that they are working with.
