METHODS AND SYSTEMS FOR IMPROVING INTERPRETATION OF FORMATION EVALUATION MEASUREMENTS

摘要

The disclosure provides methods and systems for improving the interpretation of formation evaluation measurements. The methods involve using a downhole tool to measure a property of a formation at multiple depths of investigation and calculating a spatial integrated J function, a spatial integrated K function, or both from the measurements. The J function and K function are used in different applications to improve interpretation. The system includes a tool for measuring a formation property and a processor for calculating a spatial integrated J function, a spatial integrated K function from the measurements taken at different depths of investigation. The processor may also perform interpretations such as classifications, probability distributions and initialization steps for radial inversion using the J and K functions.
