Continued innovation in modeling and algorithm development has led to new process control for the Cyberbase/SDI drilling command center. Collaboration between the International Research Institute of Stavangers AS (IRIS, formerly Rogaland Research) and National Oilwell Varco (NOV) in Developing the Drilltronics system led to succesfull land rig tests in 2006 and to field tests off Norway lstrert this year. The general concept of the Drilltronic system is to monitor and control the drilling process using continuously updated models for better control, efficiency, and safety. Continious diagnostic control allows early detection of emerging problems via a set of alarms. The Drilltronic calculates drilling limits and enforces them in real time. Current automated functionalities include automated tripping and reaming controll, automated and optimized pump-bildup control, automated well friction test (pick up/rotation/ slack off), bit-load optimization (continious drill-off), and stick slip prevention. The Drilltronic system also provides diagnostics for hole cleaning, stuck pipe, pressure, pit volume, cuttings buildup, and torque and drag.
