Title:
EXTRACTING DRILLING MODE RELATED DATA FROM WELL DATA LOGGING
Document Type and Number:
WIPO Patent Application WO2004031537
Kind Code:
B1
Abstract:
A method for generating a depth-indexed data structure for a reaming operation (620, 630) includes receiving, by a software process (730 or 760), i) well logging data (720) that includes time-indexed data and depth measurement data for an oil well drilling rig (100), ii) a selection (740 or 795) identifying a depth range for a reaming operation (620, 630) by the drilling rig (100), and iii) values for a certain parameter (780) indicating an operating mode for the drilling rig (100). Then the software process (730 or 760) extracts, responsive to the selected depth range and one of the values of the parameter (780), a section from the well logging data (720) within the selected depth range, and generates from the section the depth-indexed (750 or 770) data structure for the reaming operation (620, 630).
