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.
In January 2008, Saudi Aramco opened the Drilling & Workover RTOC, a state-of-the-art well visualization and real-time monitoring command center, to plan, drill and complete wells in the safest, efficient and cost-effective manner. The RTOC involves three critical components: People, Process, and Technology. We found that understanding each component role is crucial to develop collaborative environment that helps to promote the RTOC values.
Saudi Aramco's RTOC was opened with a lot of challenging objectives. To meet the drilling management expectations, these phases have been divided as:
The initial RTOC objective was to operate the center on critical wells, mainly offshore wells to reduce occurrence of tight hole, stuck pipe, borehole collapse, side-tracked bottom-hole assemblies (BHAs) and borehole instability problems.
The next step was to improve drilling optimization and efficiency for the monitored wells. One of the techniques used was to monitor and implement the "Mechanical Specific Energy (MSE)?? to optimize drilling parameters. Another main goal at this phase was to reduce the NPT for the monitored wells by monitoring the rig activity.
At this phase in the process, the RTOC might recommend the bit selection to increase rate of penetration (ROP). A main goal at this phase is to optimize hydraulics, hole cleaning and Equivalent Circulating Density (ECD) for Extended Reach Drilling (ERD) wells, BHA design, monitor drill string mechanics and BHA to prevent damage and reduce well control incidents.
