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.
