Directional/complex wells
In this paper, the authors propose a regression machine-learning model to predict stick/slip severity index using sequences of surface measurements.
This paper proposes a methodology for preventing drillstring fatigue and failure in deep wells with large shallow doglegs.
This paper describes a collaborative project to analyze affected wells, identify commonalities, and optimize bit design and drilling parameters to mitigate the effects of borehole spiraling.

This paper analyzes the interaction of high-frequency torsional oscillations (HFTO) with lateral vibrations based on a model that accounts for the superimposed movement of whirl and HFTO at the bit. -
In this paper, bottomhole-assembly lateral behavior is analyzed using different types of computations, including static, dynamic, frequency-based, and time-based.

The agreement formalizes JV ownership of Turnwell Industries which ADNOC Drilling created to manage a $1.7 billion unconventional drilling contract awarded in May.
-
This paper describes the qualification of a multilayer, open-cell matrix polymer system for the first horizontal deployment in an offshore gas well.
-
This paper describes installation of autonomous inflow control valves in the Bretaña Norte field in Peru, enabling effective water control even though the trial well was placed in the flank, close to the oil/water contact.
-
This paper proposes a method to radically revise the well-path-generation process to reach the vision of planning a well in one day with high quality, relying on the collection of experience-based constraints from each discipline to generate possible alternatives.
-
The authors investigate the utility of applying unconventional technology to low- or variably producing carbonate reservoirs to increase estimated ultimate recovery and decrease development-scale variability.
-
This paper details a successful pilot to improve long-term well performance using acid stimulation aided by a tailored metal oxide nanoparticle-based fluid in the Wolfcamp A formation.
-
This study highlights the strategic implementation of coiled tubing to convey perforating guns in extended-reach wells, overcoming the lockup effect through the deployment of downhole tractors and real-time monitoring tools.
-
This study introduces a detailed model to capture the physics and chemistry of acid flow in complex horizontal wells completed in carbonate formations.
