Paper presented at the SPE Conference at Oman Petroleum and Energy Show, Muscat, Oman, May 2025.Paper Number: SPE-224876 Abnormal pressure loss during a drilling operation signals a failure in the fluid hydraulics circulating system. This could be due to a washout in the drill pipe (either in the body or connection), bottom hole assembly (BHA)…
Paper presented at the SPE/IADC International Drilling Conference and Exhibition, Stavanger, Norway, March 2025. Paper Number: SPE-223786 A major challenge in utilizing physics-based models such as torque and drag (T&D), hydraulics, cutting transport, drillstring dynamics, etc., in real-time, and with high reliability and confidence has been the lack of accuracy in drillstring data available as…
Paper presented at the Offshore Technology Conference, Houston, Texas, USA, May 2025. Paper Number: OTC-35818 In an effort to enhance safety and efficiency in offshore drilling operations, this research addresses critical gaps in the current understanding and application of leading indicators for Loss of Well Control (LOWC) events. Existing indicators often fall short in predicting LOWC…
Paper presented at the IADC/SPE International Drilling Conference and Exhibition, Galveston, Texas, USA, March 2024. In today’s well construction operations, a substantial volume of data is generated and stored across multiple databases. The primary objective being to use them as a guide for future well construction optimization. However, much of this data gets lost in…
Paper presented at the International Petroleum Technology Conference, Dhahran, Saudi Arabia, February 2024. Paper Number: IPTC-24141-MS When stuck pipe incidents happen, they can drastically increase the cost of a well. Although much progress has been made in stuck pipe prevention it has not been eliminated. Therefore, there is an ever increasing need to be able to…

Paper presented at the SPE Annual Technical Conference and Exhibition, San Antonio, Texas, USA, October 2023. Paper Number: SPE-215132-MS Developing artificial intelligence (AI)-based drilling advisory software is generally straightforward when good quality labeled data are available. However, deploying such systems in the field for use by a rig crew requires careful planning and execution and…
Paper presented at the SPE/IADC Middle East Drilling Technology Conference and Exhibition, Abu Dhabi, UAE, May 2023. Paper Number: SPE-214608-MS During well construction, it is important to know when a bit is damaged to the point where it must be tripped out and replaced with a new bit. Continuing to drill with a damaged bit…
Stanford Geothermal Workshop, 2024. Efficient drilling of geothermal wells hinges on a thorough comprehension of temperature distribution along the wellbore, vital for preventing tool failures and reducing non-productive time (NPT). This involves ascertaining the requisite mud cooling at the surface and optimizing circulation flow rates to extract heat effectively. While extensive theoretical work exists in…
During well construction, automatic monitoring of the sensor signals for drilling dysfunction detection through pattern recognition algorithms is key to improving rate of penetration (ROP) and preventing tool failure. The addition of physics-based models can enable further improvement, but often one is limited by the contextual data needed by these models, as well as the…
