Petrophysics for Dummies
24 January 2010
Here is my Beginner’s Guide to Petrophysics. The full movie lasts over an hour - so I’ve split it up into these chapters:
Permeability: from Cap-Curve to FLowrate
8 February 2010
Here I attempt to show how Saturation Height modelling can be used in permeability prediction and validate this with PLT spinner data:
1. Introduction - Capillary Pressure
2. Field Example
Pickett PLOT Essentials: The Graphical Archie SoLution
14 March 2010
Originally made for the PP for Dummies Seminar, here I’m trying to show the basics of resisistivy analysis & pore space behaviours:
Residual Oil:
Logging Behind The Flood Front
18 April 2010
Work I did back in 2003 to try and quantify the Residual Oil Prize for the Magnus EOR scheme when I used to work for BP:
1. Introduction - Concepts & Issues
2. Magnus Field Example
1. Methodology
2. Applications I
3. Applications II
FLOW-CONDITIONED
PERMEABILTY
Modelling
21 August 2010
Recent work summarising my approach to permeability modelling. Here I attempt to show that the use of flow profiling gives additional reservoir insights and a more meaningful assessment of permeability prediction quality. The Applications presentations show this approach used in upscaling, cut-off determination and flow-rate prediction sensitivity.

PETROPHYSICS: More Important Than Ever
17 April 2011
Presentation made to MSc students - to show the value of petrophysics in mature field environments. With less than 100 petrophysicists working in the UK....there’s potentially a lot of work out there.
Conglomerator: The Trouble WITH ROCKS
3 July 2011
This presentation uses quantitative image analysis and core data to create a petrophysical simulation tool using an Excel random number generator & appropriate property distributions.
1. Introduction
2. The Spreadsheet Instructions
3. QC Examples
Saturation Height:
A Practical
Approach
15 September 2011
Presentation made to both the Aberdeen Formation Evaluation Society (AFES) and London Petrophysical Society (LPS). It’s called a “practical approach” because it describes the use of an Excel Modelling spreadsheet - contact me here if you would like a copy. Of course, I cannot accept responsibility for any of your results, or for any problems you may encounter, with this tool.
