Course Code: N569
Instructors:  Adam Moss
Course Outline:  Download
Format and Duration:
5 days
10 sessions

Summary

Participants on this course will learn to measure and integrate conventional and special core analysis (SCAL) data into static and dynamic reservoir models. The expert instructor has over 25 years’ experience working in core analysis laboratories and an operating company.  The course is structured to demonstrate the complete workflow from core acquisition to reservoir model consruction.

Duration and Training Method

This classroom or virtual classroom course will comprise short lectures and discussions followed by practical exercises to embed understanding.

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. Clients are encouraged to provide examples of their own core analysis data, so these can be included in the practical workshops.

This course is also available in a shortened 4-day classroom or 8-half-day virtual classroom format.

Course Overview

Participants will learn to:

  1. Design a core analysis programme to supply all data required for reservoir modelling.
  2. Perform quality checking of core analysis data.
  3. Build a saturation height function for use within the reservoir model.
  4. Measure and quality check relative permeability data, and integrate these data into the reservoir model.

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.
