PETRONAS Carigali Sdn. Bhd. (PCSB) Wells Department (formerly known as Drilling Division) has long realized the importance of drilling and delivering most cost-effective Wells for the Exploration and Development segment, by establishing the PETRONAS Digital Collaboration Centre (PDCC), which serves as a decision support platform for stakeholders to monitor, reduce, and eliminate operational and safety problems during drilling, but a piece of the puzzle is still missing - to measure the well activity performance.

The earlier arrangement heavily relied on human factors such as the time-consuming logs that were completed manually by the PDCC personnel within 7 days after each completed well section. The analysis was done manually using excel spreadsheets, only focusing on major well activities, for example running the casing/liner and connection time. However, no pro-active action was taken during the operations to improve the performance. Furthermore, there is no ability to intervene with the rig performance in real time and adapt a technical limit approach. The Operational Excellence coach has limited experience and no tools to measure the technical limit, which also leads to a knowledge gap in wells performance and benchmarking areas of the drilling engineer's portfolio.

The implementation of the new artificial intelligent tool, presents revolutionary management challenges for people, process, and technology within the PCSB, aligning with Well's House vision to be "World Class Well Delivery – Preferred Solutions Partner".

This paper presents the business requirements and implementation of the PETRONAS Wells Performance Tool, and also describes the comparison between the previous approach and the challenges faced with implementing the new solution.
