MWD and Gyro Survey Tool Quality Management System

Abstract This paper describes a Measurement While Drilling and gyro survey tool quality management system. A first objective of the system is determining a definitive survey, by use of real time quality control parameters. A definitive survey is meant to have a quality that is meeting its theoretical or planned and approved wellbore position uncertainty. Further, field examples of the system application are presented and reviewed. A second objective of the system is delivering a self-contained reference for survey data quality management containing a quality control process, quality control procedures and quality control tolerances.
