Next Event
A course designed to help attendees design core analysis and SCAL test programmes for both oil and gas reservoirs and carbon capture storage (CCS) in aquifers and depleted gas and oil reservoirs. The participants will also learn how to quality check and use legacy core analysis and SCAL data. The course builds on 30 years’ experience working in core analysis laboratories and an operating company and is structured to demonstrate the complete workflow from core acquisition to petrophysical and reservoir model construction.
Schedule
Duration and Training Method
This classroom course will be a combination of short lectures, practical workshops and plenary discussions to consolidate learning. 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. Practical exercises use real core analysis and SCAL data.
Participants will have opportunities to share their own experiences, discuss data and explore any issues they may have had relating to core analysis and SCAL data. We encourage the clients to send us examples core analysis data, so these can be included in the practical workshops.
Course Overview
Learning Outcomes
Participants will lean to:
- Design core analysis & SCAL test programmes to supply all data required for petrophysics and reservoir modelling in both conventional reservoirs and CCS.
- Perform quality checking new and old core analysis & SCAL data.
- Describe how core and log data are depth matched.
- Select samples for conventional oil and gas reservoir and CCS analysis.
- Review core mineralogy data.
- Stress correct porosity & permeability data to account for initial reservoir stress & depletion.
- Define the test and data analysis methods to determine capillary pressure versus water saturation curves, capillary entry pressure and seal capacity.
- Measure and quality check relative permeability data for conventional reservoirs and CCS studies.

Adam Moss
Background
Dr Adam Moss is a core analysis expert with over 25 years’ experience working in petrophysics. Dr Moss runs AKM Geoconsulting Ltd, which he founded in 2017 to offer core and special core analysis consulting services and training to industry. Adam has an established track record in teaching and research in academia and is an Honorary Assistant Professor at Heriot-Watt University.
Following his PhD on the ‘Characterisation and Modelling of the Pore Structure of Reservoir Sandstones', Adam worked as a Research Associate at Imperial College. He subsequently became the Senior NMR Petrophysicist at ResLab UK in 2001 with responsibility for all aspects of the company’s NMR core analysis services. From 2006 to 2016, Adam was the Global Group Technical Authority for Core Analysis at BG Group, where he was responsible for all aspects of BG Group’s coring and core analysis projects worldwide. This included defining best practice workflows and working with assets and multi-functional teams to ensure core analysis data was of the best quality and used appropriately.
Adam's passion is to help different functions (petrophysicsist, reservoir engineers, geologists, geophysicists, drillers, and production technologists) integrate new methods and research findings into their workflows and reservoir models. He regularly publishes and referees research papers for The Society of Core Analysts, Society of Petroleum (SPE) journals, Petrophysics (SPWLA), Journal of Petroleum Science and Engineering, Petroleum Geoscience, and Transport in Porous Media. Adam served as President of the London Petrophysical Society (LPS) from 2010-2012.
