This paper details the formulation and characterization of a novel nanoparticle system composed of polyethyleneimine and dextran sulfate for direct lithium extraction from bulk oilfield brines in North America.

As the exploitation of hydrocarbons moves into increasingly challenging scenarios, the ability to enhance the strength of available tools so that they can create a whole greater than the parts is no longer an option but a necessity. This year’s Field Development selections reflect this need for optimization.

The need for sustainable innovation, efficient resource planning, and a greater understanding of subsurface science through applied chemistry is greater than ever. Three papers were selected based on their forward-looking approaches to these challenges.

Updates about global exploration and production activities and developments.

As of mid-2025, more than 50 CCS facilities are capturing approximately 51 million tons of CO₂ annually, with over 600 additional projects in the pipeline. Yet the success of these efforts rests on a single truth: If we cannot monitor it, we cannot manage it.

The offshore industry is actively embracing a digital-first, low-carbon future, supported by scalable demonstrators, intelligent systems, and integrated engineering approaches now entering precommercial or early-deployment stages.

Intelligent completions could improve many of the world’s oil and gas wells, but not all are suited to the technology. There is another option.

This article is the fourth in a Q&A series from the SPE Research and Development Technical Section focusing on emerging energy technologies. In this piece, David Reid, the CTO and CMO for NOV, discusses the evolution and current state of automated drilling systems.

Oil and gas experts encourage human/AI partnerships that can “supercharge” capabilities to create competitive advantages.

Casing deformation has emerged as a major challenge in China’s unconventional oil and gas fields, prompting the development of new solutions to address the issue.
