Abstract:
1. A method for characterizing a sample of porous media using at least one measuring device and a multipoint statistical (MPS) model, the method comprising: a) retrieving one or more sets of reflected measured data provided by the at least one measuring device of at least one portion of a surface of the sample to produce a sample imaging log, wherein the retrieved one or more sets of measured data is communicated to a processor; b) using at least one noise reduction algorithm to identify noise data in the retrieved one or more sets of measured data; the identified noise data is one of removed from the retrieved one or more sets of measured data, replaced with null values or both; c) selecting depth-defined surface portions of the sample from the sample imaging log as a training image for inputting in the MPS model; d) determining pattern based simulations from the training image using at least one of a pixel-based template which is applied to the training image; e) constructing from the pattern based simulations one or more sampling image logs of surface portions of the sample; and f) repeating steps (b) to (e) through the one or more logged surface portions in order to construct three dimensional (3D) sample images from stacked successive pattern based simulations to construct at least one 3D model of the sample.
