Abstract
Remote Casing Control (RCC) is an initiative of the Wellsite Geology Division with the support of Aramcolink. The aim of the RCC team is to provide 24/7 geological support about casing points remotely. Real-time data transmission and the advanced correlation tool are the basic requirements to achieve the end objective of picking the formation tops and casing points remotely.
This paper describes the case study that illustrates the great impact of utilization of real-time data transmission and advanced real-time tools to pick casing points and formation tops remotely. The RCC team monitors the active well operation remotely with the help of real-time data streamed by Aramcolink. Moreover, Aramcolink has developed a logic/algorithm to calculate Drill Time from the streamed realtime data. Additionally, the mud logging unit can upload and share the lithology data RCC through the Aramcolink portal. This real-time data is being displayed/exported and downloaded from the Aramcolink viewer. Later it is being used to correlate with some offset wells of the same or a nearby field. Based on the similar signatures of Drill Time and lithology data, formation top and casing points are being picked/ designed. Other than shallow casing points, the RCC team is also picking the 7" liner point remotely with the aid of a mud logging unit to provide them with the lithology and gas readings where the deeper section ROP is not enough to decide and pick the formation tops or casing points. The RCC team also uses RigChat to effectively communicate with rig personnel and keep involved parties informed.
This technique decreases the operational cost and avoids the mobilization of a dedicated wellsite geologist on each rig.
Ease to manage multiple wells at the same time from office location
Effective surveillance and monitoring of the drilling operation
Timely and collaborative decisions to save the rig time
Effective communication with all involved parties
Reduced travel and physical exposure which may cause HSE concerns
Minimized logistical cost
Record of the historical data for quick quality control (QC)
Fast and flexible data interpretation with remote expert support
Real-data accessible for surveillance at anytime, anywhere with Extranet
Hence, saving time and costs, improving safety, boosting business and return on investment
The reliance on high quality real-time data from oil and gas operations has been significantly increased in the past few years. High rate real-time data is the baseline for critical remote analyses and decisions that can lead to a maximized oil/gas recovery, increasing the revenue, reducing the operational cost while minimizing the HSE concerns.
