Drilling
As managed pressure drilling gains traction, its principles are influencing a wider range of well-construction activities.
This paper presents laboratory-testing methods and evaluation criteria designed to improve understanding of both the origin and extent of formation damage associated with CO2 injection.
This work introduces an analytical model for nonisothermal CO2 injection that accounts for both Joule-Thomson cooling and interformation heat exchange.

To enable a fully interventionless approach, a barrier-rated tubing-hanger valve has been developed to eliminate slickline intervention and minimize associated risks and operational time. -
This paper describes an intelligent completion system in the context of multiple wells that, by electrifying the process, replaces the conventional electrohydraulic systems that have been in use for decades.
-
New case studies highlight how artificial intelligence, advanced hardware, and innovative business models are enabling success in drilling automation.
-
This paper evaluates the effect of rapid cooling on the rock-cutting process and incorporates this effect as a component of drilling-performance optimization.
-
This paper discusses the development of a multientry, multistage fracturing system and its advantages over traditional openhole multistage fracturing solutions.

In a deal described as possibly "one of the most important transactions BP has done in 20 years" by CEO Murray Auchincloss, the company has agreed contractual terms with the Iraqi government to invest in drilling and infrastructure to rehabilitate and boost production at the Kirkuk oil field.
-
Soft demand and mounting stacking costs drove decisions by Noble and Valaris to move on from units.

From optimizing drilling performance to enhancing worker safety, computer vision can change how the industry works.
-
In this paper, the authors propose a regression machine-learning model to predict stick/slip severity index using sequences of surface measurements.
