... ). This sets the initial casing depths, using a bottom-to-top approach coupled with the RDFM modeling approach. The expected kick volume distribution for each section is then defined, combining the formation flow performance and the kick detection and control capabilities. This sets the kick volume limit...

.... The effectiveness in mitigating stick-slip can be further improved through active control of the damping strength of one or several subs. This paper evaluates a control scheme, which relies only on local downhole measurements, for various operating conditions simulated with a drill string mechanics model. Damping...

... due to motor failure include: Abstract Drilling process automation has been a trending topic within the technical community, most recently discussed in SPE-212565-MS ( Cayeux et al. 2023 ). Recovery control - specifically in the case of motor stalls - is not only integral to consistently...

.... Temperature management that relies heavily on surface cooling is currently mostly a manual process. This paper presents a control-oriented platform to achieve automated managed temperature drilling in real-time. For the controller, an improved reduced drift-flux model that considers temperature dynamics...

... moments, and to recreate real-world adverse conditions such as vibrations, stick-slip, and twist-off. Sensors and actuators positioned along the experimental setup allow control of the rotational and axial velocities, contact forces at various locations, and adjustment of the magnetic braking force. Stick...

.... The automation technology transfer is not a straightforward task because the two RSS systems are different in steering mechanism, the type and noise level of the sensors, the positions of the direction and inclination sensors, their filtering characteristics, and the current downhole control system...

... required precise positional control to enter the reservoir in the correct location and with the correct attitude. At the end of the section, with over 1500 m drilled, the final well position was 0.28 m above the target position and 3.89 m to the left, with minimal tortuosity, making it easy to land...

... and does not require tuning. Following a dozen or so Z land rig deployments since 2015, the technology was added to a heavy offshore rig, a newbuilt, with modern hi-end variable frequency drives that enable near-zero control loop latencies. A study validates the effectiveness of the system with downhole...

... of stick/slip mitigation is through control of the top drive. In existing applications, the vibrational wave at a fundamental frequency is absorbed by tuning a proportional-integral (PI) controller. Stick/slip-induced vibrations do not exist at a single frequency, and the simple PI controller cannot...

... Abstract Riser gas unloading events in deepwater subsea well construction operations are very hazardous and difficult to control. Gas kicks may go unnoticed when gas dissolves in non-aqueous fluids (NAF), with dissolved gas volumes not showing significant pit gains on surface when conventional...

.... During the 2015 & 2016 drilling campaigns, efforts to optimize the on-bottom drilling performance did not focus on how the control system affected downhole performance. Such observations were made, however, during the 2017 drilling campaign, when we learned that some of the stick-slip experienced...

... Abstract Increased use of Managed Pressure Drilling (MPD) has enabled a significant improvement in drilling operations through the ability to accurately control pressure within a narrow window and by actively managing the annular pressure profile. However, the technology has not yet reached...
