Implementing total operational surveillance can provide a detailed statistical breakdown of each rig's activities within an operation, enabling operators to accurately measure operational efficiency and flagging potential downtime events. PETRONAS has embarked on a full scale rigsite since 2010 with the setting up of a comprehensive operations surveillance monitoring center (Smart DOMC). This paper describes the process and benefits of streaming down rigsite operational information and data on a real-time basis to the monitoring center. The Smart DOMC has become a center of excellence for domestic knowledge sharing, exchanging information, as well as a database of best practices, systematic trouble shooting, applied technologies, and capturing lessons learned. Very soon, the Smart DOMC will monitor all PETRONAS Carigali operations worldwide, which will encompass almost all drilling operations including land jobs, offshore operations, deep water, high pressure/high-temperature (HP/HT), carbonate drilling and unconventional technologies. These complex operations must be monitored and supported with robust infrastructures and competent manpower within the monitoring center. Operationally, high-resolution tools and sensors (surface and downhole) must be installed at the rig site for automatic data generation and transfer to the Smart DOMC by means of satellite. This information is segregated to produce reports related to wellbore integrity, formation evaluation, bottom hole assembly (BHA) performance, and drilling efficiency. Proprietary software is then used to transform digital data into presentable graphical formats for further evaluation and data storage. Implementation of such engineering and data surveillance were implemented in recent drilling campaigns in the Angsi Field, Sumandak, Tangga Barat, and Sepat projects. USD millions were saved by eliminating potential non-productive time (NPT) events and implementing efficient decision making. Obtaining accurate statistical data from each rig's operations allowed drilling management to reduce the NPT to barely minimum i.e., less than 5%. |
