GEOL40590 Geostatistics and geomodelling

Academic Year 2023/2024

Using a geomodel to quantify the value of a resource or to forecast its future behaviour often requires assigning physical properties to the model. This 2.5 credit module reviews the methods used to extract statistics from subsurface data and addresses how they are used in geomodelling. Lectures are focused on providing a grounding in the principals of the methods while practical classes are devoted to construction and analysis of geomodels using industry-standard software.

Learning Outcomes:

By the end of the module students should be able to:
Understand the definition, calculation method, and practical significance of key geostatistical properties.
Describe, and apply in Petrel, typical methods for constructing models for flow simulation

Indicative Module Content:

The 10 lectures follow the workflow of geostatistical characterisation and modelling guided towards construction of a sub-surface flow simulation model. The five practical classes follow the work-flow used to characterise and model flow units for flow simulation modelling, based on published datasets and modelled in Petrel.

Approaches to Teaching and Learning:
The module combines lectures and 3-hour practical classes. Lectures will focus on developing concepts using theoretical considerations and illustrative case-studies. The practical classes will mostly use Petrel for analysis and modelling of spatially varying properties.

Feedback Strategy/Strategies

• Feedback individually to students, on an activity or draft prior to summative assessment
• Feedback individually to students, post-assessment

How will my Feedback be Delivered?

Ongoing practical work will be discussed with students individually and collectively whist it be being performed during the scheduled practical classes. Post-assessment feedback will be provided as sought.
