Oilfield chemistry
This article addresses the challenges of managing water-soluble organics (WSOs) in offshore produced water. It provides a brief discussion of the chemistry, along with strategies and technologies that can be used to manage WSO levels in produced water, thus facilitating compliance with regulatory overboard water-quality guidelines.
A new licensing deal with ZL Chemicals will make Chevron’s unconventional EOR technology available to other tight-oil producers.
This case study presents a procedure in which the operator compared production from wells with adjusted wettability to a control group, finding that the adjustments resulted in significant improvements in production and reductions in produced water.

This paper reviews existing literature, the operator’s records, service-company data, and simulation studies to assess the risk of using seawater in carbonate acidizing. -
A laboratory research study evaluates several different chemical injection concepts for the removal of elemental mercury from multiphase flow.

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.
-
The authors of this paper aim to design, optimize, and evaluate a scalable and energy-efficient plasma-driven advanced-oxidative-process system for produced-water remediation, emphasizing regulatory compliance for safe discharge or reuse.
-
A new tubing-conveyed tool combines wellbore cleanout with multi-tracer deployment for production diagnostics and reservoir monitoring.
-
This study compares water-based chemicals including surfactants, nanoparticles, and ketones that can be used for enhancing the oil recovery of shale-oil reservoirs.
-
The experience captured in this paper illustrates the potential of deepwater riserless wireline subsea intervention capability and the fact that it can be expanded beyond hydraulic-only, simple mechanical, and plugging-and-abandonment scopes.
