An Effective Approach for Automatic Rock-Typing and Calibration Using Single-Well Models

Rock-typing is an essential ingredient for any static or dynamic modeling; it is the link between depo- or lithofacies and their<br>pore geometries and the fluid flow properties. The rock types determine porosity-permeability transforms and initial water<br>saturation in static models and govern properties that directly impact fluid flow behavior (such as relative permeabilities or<br>rock compressibilities). With this in mind, they are guiding elements for most decisions on well and infill-well placement<br>today, at least wherever reservoir models are used.
