The complete paper provides an approach using machine-learning and sequence-mining algorithms for predicting and classifying the next operation based on textual descriptions.

The complete paper describes an automated machine-learning approach to determine the spatial variation in decline type curves for shale gas production, based on existing data of production, completion, and geological parameters.

The author of The Prize talked recently about his newest book on the energy transition and what he sees as the most dynamic forces shaping the things to come.

Sand control has evolved over the years; however, the fundamentals of screen sizing have not changed. Particle-size distribution remains the basis for most designs. Laser diffraction has provided better definition of fines, and greater focus is placed now on particle-shape characterization.

The question is: Why do workers continue to get injured on the job despite federal standards interjecting?

Traditionally, a wellhead system requires a drilling lockdown sleeve (LDS) during drilling operations to ensure that the seal assembly is rigid and prevents dynamic movement. By eliminating the LDS, however, the operator will save multiple trips into the well.

The complete paper describes the hurdles that have prevented single-trip installation of upper and lower completions in the complex world of subsea and deepwater applications and examines the processes, technologies, and risk-mitigation steps that took a concept from pilot to successful deployment.

With reduced new unconventional well activity, practices such as frac-hit mitigation—pressurization of parent wells during child-well fracture stimulation—have become increasingly important to reduce parent-well proppant cleanouts as well as to maximize production from both parent and child wells.

The complete paper describes the development and implementation of a glass-plug solution that closed the technical gaps that had previously inhibited fully intervention-free operation for completion installation.

The complete paper reviews the results of gas hydrate engineering and production testing studies associated with northern Canada and Alaska.
