  • Why and What are the Goals

This course delivers how to determine structural interpretation such as orientation, fracture attributes, and fracture density distribution from macro to micro scale and how to integrate those structural interpretations.

In this course, we will use the analog from Basement Outcrop in Indragiri River representing the basement analog in Sumatra to determine these different scale fractures. First, the instructor will guide how regional context in geology is critical to understanding data correctly by using remote sensing interpretation. Second, we will observe mesoscale basement discontinuities utilizing a combination of the Three Dimensional Outcrop Model (DOM) as well as detailed outcrop observation and linear scanline fieldwork to determine the geometry and behavior of the structures. Third, we will see the thin sections for microstructure analyses and relate them to fundamental fluid dynamics. An integrated analysis will then be carried out to develop the structural analysis, especially to build the fracture analog.

  • Who is this training course for?

Concern in structural geology, petroleum geology, and geothermal exploration.

  • Workshop Impact

Nowadays, structural geology is the general method and can be applied to several industries. Especially natural fractured analysis can be useful for conventional and unconventional energy and renewable energy like geothermal exploration. Knowing how to determine structural or natural fracture in every scale can make us understand the genetic geometry until the properties implicate the general structure interpretation and analysis in every industry sector.

  • Workshop Delivery

Introduction to fracture and faults in geology.

The instructor will introduce a basic explanation of fractures and faults and their mechanics. Importance of mechanical stratigraphy, heterogeneity of deformation caused by the complexity of flow of stress.

Interpretation of Large-Scale Structures

  • Scale independent and dependent in geology
  • Understanding structural elements from simple DEM data.
  • Some concepts and applications of remote sensing structural interpretation
  • Simplified DEM processing for better structural interpretation (TRI, slope, aspect, and TPI) using QGIS
  • Structural province clustering
  • Interpretation Session

Structural Identification from Fieldwork Data

In this section, the instructor will introduce the basic theory, methodology, and some of the research carried out by DOM for structural interpretation. With this module, the instructor will provide several examples of how photogrammetric data becomes the DOM and interprets the structural geology of this data. Furthermore, the instructor will introduce scanline and windows scan methods for determining structural characteristics or fracture attributes in the field, such as fracture aperture, fracture length, and fracture spacing, to determine fracture properties. A guided exercise of fracture intensity analysis and fault identification will be an integral part of the module.

Microstructure interpretation, Integrated Structural Identification, and Application

The instructor will introduce sampling methodology for structural analysis and rheology, especially mineralogy in granitic rocks, affecting fracture density in thin sections and the sample distance to the fault. The fault zone will be approached with fracture analysis integrated into microfracture analysis with DOM. In this section, participants will be introduced to integrating all structural scale interpretations and those applications, such as distributing fracture density models based on thin-section analysis combined with DOM analysis for lateral distribution. Fracture attributes in the field will be the primary data for building Discrete Fracture Network (DFN) properties. And with that DFN, we can create Basement Fracture Analog at the end of this course. And at the last section, the instructor will explain how to integrate the fractured data to build the fractured analog.
