Oilfield chemistry
Marking a major milestone as the Gulf of Mexico’s second 20,000-psi deepwater development, the project underscores how advanced high-pressure technology, management of flow challenges, and the floating production system’s role as a regional hub are helping open the door to more Inboard Wilcox development.
This paper describes a decision-support system that integrates field data, system specifications, and simulation tools to quantify system performance, forecast operational challenges, and evaluate the effect of system modifications in water management.
This paper demonstrates that high-purity salts of calcium, magnesium, strontium, sodium, and lithium can be recovered from produced-water brine using a chemical-reaction pathway followed by vacuum-driven crystallization and a lithium-extraction process.
