Directional/complex wells
This paper establishes that the use of a dual-gradient fluid column during the running of large casing in an extreme-reach deepwater well is an effective method to overcome drag and enable the casing to reach total depth.
This paper presents the first global application of autonomous drilling in deepwater and the journey to reach optimal drilling parameters, integrating proprietary tools from the project’s business partners.
In this paper a case study is described in which a software solution enabled prescriptive optimization of well delivery using a physics-informed machine-learning approach for predictive identification and characterization of well-construction risks.

SponsoredAltitude Energy Partners optimized drilling efficiency by minimizing dysfunctions and protecting downhole components. Their directional drilling team ensured consistent curves and laterals through precise BHA design, modeling, and trajectory control—reducing nonproductive time and drilling costs, and achieving a 100% improvement in efficiency by pad completion.
