C1: Best Practice in Core Handling & Analysis

2024 Programme

3 Days | £1500+VAT per attendee

Course Aims

To provide an understanding and appreciation for best practice in core handling and processing. Provide an awareness of the effects of mineralogy and heterogeneity on core and log data quality. Be able to design a core sampling strategy and build a core analysis programme for all stakeholders.
The course will be a combination of short lectures, practical workshops and plenary discussions to consolidate learning. Each topic will be presented by the expert tutor using MS PowerPoint presentations.  Sessions will be structured carefully to ensure optimisation of learning expectations verbally and on PowerPoint, followed by practical exercises to embed understanding. Discussions and question and answer sessions are encouraged to ensure understanding. Each session will contain a practical exercise which will be either on paper and in Excel. Attendees should be familiar with basic calculation and charting functions in Excel. Attendees will have opportunities to share their own experiences, discuss data and explore any issues they may have had relating to core and core analysis data.

Delegates Will Learn:

  • About different coring techniques

  • How to recover and process core safely and competently

  • The importance of heterogeneity and mineralogy and their effects on sampling strategy

  • How to design a core analysis test programme and work successfully with laboratories

  • How to measure porosity, permeability and water saturation in core

  • Gain an understanding of methods to integrate core analysis data with log interpretation and geological models.
