Drilling
This paper highlights a new online system for monitoring drilling fluids, enabling intelligent control of drilling-fluid performance.
A proposed integrated workflow aims to guide prediction and mitigating solutions to reduce casing-deformation risks and improve stimulation efficiency.
This paper investigates the use of machine-learning techniques to forecast drilling-fluid gel strength.

This case study discusses the methodology that underlies the successful determination of the depths and the radial locations in the outer casing strings of multiple leaks in an offshore well. -
This paper focuses on the preparation for, and implementation of, well-control training, while highlighting the integration of people skills into curricula and what advantages operators and drilling contractors have obtained.
