METHOD AND APPARATUS FOR MULTIDIMENSIONAL DATA ANALYSIS TO IDENTIFY ROCK HETEROGENEITY Russian patent published in 2013 - IPC G01V1/30 

FIELD: physics.

SUBSTANCE: disclosed are methods, apparatus and computer readable medium, having a computer usable program code for identifying regions in the ground at a well site (200), based on that continuous data (902) are received from the well site (200), while reducing redundancy in the continuous data (902) received from the well site (200) to form processed data. Cluster analysis is performed (2308) using the processed data to form a set of cluster elements, where the set of cluster elements (1402) includes different types of cluster elements which identify differences between regions in the ground at the well site (200). Properties are identified for each type of cluster element in the set of cluster elements (1400) to form a model for the well site (200).

EFFECT: methods, apparatus and systems for multidimensional data analysis to identify heterogeneities in formations or regions in the ground, with simultaneous elimination or minimisation of the effect of existing problems and constraints, providing different orientation when taking lateral sample, providing visual display of zones with the best reservoir bed quality, which provides the best potential for commercial extraction for a specific well.
