The objective of this paper is to discuss Saudi Aramco's Drilling RTOC (Real-Time Operating Center) experience in developing personnel, establishing process workflow and acquiring technologies to deliver wells safely and effectively. The paper starts by describing the IT infrastructure that facilitates rapid information flow from drilling sites to the RTOC. Then it discusses the process workflow, which includes pre-drill collaborative planning, real time predictive modeling, and 24/7 monitoring services to provide accurate response to real time trends for successful management of drilling risks, and therefore reduction of nonproductive time (NPT). Finally, overall achievements of 2008-2009 and a case study of one monitored and optimized well is presented.
