FESQ September 2019 Seminar in Brisbane

 Registration is closed for this event

Quantifying Petrophysical Uncertainty . Why is it important and how should we do it?    

Presented by Rick Aldred, Consultant

Rick Aldred September 2019 FESQ speaker

 Asset value is generally based on ‘proven’ estimates of hydrocarbons in place and it is uncertainty that separates the ‘proven estimate’ from the ‘best technical estimate’. Therefore, quantifying petrophysical uncertainty is the key to demonstrating the value of data and the value that Petrophysics brings to an asset.

There are various methods commonly used for modelling petrophysical uncertainty and it is essential that they are applied correctly. To illustrate this a comparison of different methods is presented, highlighting the strengths and weaknesses of each and demonstrating how inappropriate techniques generally over estimate uncertainty and reduce asset value. 

Uncertainty modelling also provides a method for understanding the value of information which helps in determining priorities, designing ‘fit for purpose’ logging and coring programs and justifying the costs of each aspect of data acquisition and interpretation.

The presentation will also discuss how petrophysical uncertainty is addressed in the Petroleum Resource Management System (PRMS) and consider opportunities for reviewing this reference, now that the SPWLA is involved.
