The Archie Equation is a mainstay of conventional petrophysical analysis, but what exactly is it? How was it created and what the various factors and exponents actually mean? It is important to understand these things, since the saturation estimates from the Archie Equation may be critical in our STOIIP estimations, upon which the success of […]

What is Porosity?
Porosity is such a fundamental part of the reservoir. One of the key parameters that we routinely measure. But what exactly are we measuring and do all measurements give the same value? Check out this cheat sheet to see the possibilities. Has Greg missed anything? When does it really start to matter? Download the Porosity […]
STOIIP is a core part of any petroleum exploration and production workflow, so we all need a clear understanding of what STOIIP is and where the numbers come from . This is Greg’s attempt to try and pull all the key elements of STOIIP together on to one sheet. Take a look and let Greg […]
