Paper presented at the IADC/SPE International Drilling Conference and Exhibition, Galveston, Texas, USA, March 2022. Paper Number: SPE-208745-MS. Published: March 01 2022. During the construction planning phase of any new well, drilling engineers often look at offset well data to identify information that could be used to drill the new well more efficiently. This is generally a…
Paper presented at the SPE Annual Technical Conference and Exhibition, Dubai, UAE, September 2021. Paper Number: SPE-205984-MS. Published: September 15 2021. Current slide drilling practices rely heavily on the intuition of the directional drillers to identify and correct drilling dysfunctions. Monitoring numerous dysfunctions simultaneously requires more complex analysis than can be done manually in real-time. There is…
Paper presented at the SPE Annual Technical Conference and Exhibition, Dubai, UAE, September 2021. Paper Number: SPE-206340-MS. Published: September 15 2021. Kick and lost circulation events are large contributors to non-productive time. Therefore, early detection of these events is crucial. In the absence of good flow in and flow out sensors, pit volume trends offer the best…
Paper SPE-204125-MS, presented at the SPE/IADC International Drilling Conference and Exhibition, Virtual, March 2021. The paper proposes a method that relies on the detection of events over a long time horizon and the use of key parameters relating to such events to quantify hole cleanliness. These events are then related through duration and frequency to…
Paper SPE-204063-MS, presented at the SPE/IADC International Drilling Conference and Exhibition, Virtual, March 2021. Detecting drilling dysfunctions from surface data is not always easy as downhole vibrations tend to get damped before they reach surface sensors. Building machine learning models to recognize patterns in the surface data requires vibration signals captured by downhole sensors for…
Paper SPE-194184-MS, presented at SPE/IADC International Drilling Conference and Exhibition, 5-7 March, The Hague, Netherlands, 2019. The system used for this paper consists of a Rig-based Drilling Advisory System (RDAS) where new advisory information is displayed in the driller’s cabin running real-time pattern recognition algorithms to detect drilling dysfunctions. When a drilling dysfunction is encountered,…
Paper SPE-191426-MS, presented at the SPE Annual Technical Conference and Exhibition, 24-26 September, Dallas, Texas, 2018. The drilling industry has made significant progress on physics-based torque and drag (T&D) models that can run either offline (pre-job or post-job) or in real-time. Despite its numerous benefits, real-time T&D analysis is not prevalent since it requires merging…
Paper SPE-191797-MS, presented at the SPE Liquids-Rich Basins Conference – North America, 5-6 September, Midland, Texas, 2018. The first step towards drilling optimization and automation is a reliable data acquisition and handling system. This includes receiving and processing different frequency data across multiple platforms and ensuring proper data quality. Once we implement such a platform,…
Paper IADC/SPE 189700, presented at the IADC/SPE Drilling Conference and Exhibition, Fort Worth, Texas, March 6–8, 2018. Recently, Intellicess applied unique beliefs-based early detection and alerting system to drillstring washout and pump failure detection during drilling. The methodology was used to focus primarily on the time signatures of real-time and modeled pump pressure in relation…
Paper SPE 186166, presented at the SPE Offshore Europe Conference and Exhibition, Aberdeen, Scotland, UK, 5-8 September 5-8, 2017. (DOI: 10.2118) Currently, because available drilling data is uncertain and humans cannot aggregate and act appropriately on multiple data streams in real time, adjustments to drilling parameters are based primarily on experience. This paper describes a…
