0 Replies and 185 Views An AAPG/SPE Contradiction 185 0 Started by James Dietrich Dear Colleagues: There is a contradiction between the positions taken by the AAPG and the SPE on the need for the routine use of property cutoffs in reservoir modeling. The SPE tacitly supports an approach to model building that eliminates hydrocarbons initially in-place in rock of low permeability, where little or no flow is expected to occur. This implied backing derives mainly from refereeing and publishing the work of Worthington and Cosentino (2005), and Worthington (2008 and 2010). I...

0 Replies and 174 Views Pore Space Connectivity 174 0 Started by James Dietrich Dear Colleagues: It's been alleged by many that a systematic error runs through the practice of reservoir modeling. The alleged error involves use of the variogram. Briefly stated, it's alleged that geo-modelers simply assume spatial dependency of rock properties over distances of 100s to 1000s of meters (within a given facies) based on the well spacing that happens to be available to them when modeling petroleum reservoirs, whereas property correlation lengths revealed via evaluation ...
