Oilfield chemistry
The 2026 Upstream Scale Guidelines establish a common workflow for field measurements, scale modeling, and risk assessment to support more consistent operational decisions.
This study explores the carbon-capture and mineralization potential of ultramafic rock powders when exposed to flue gases generated from combustion of crude oil and mesquite-derived charcoal.
The legacy of per- and polyfluoroalkyl substances (PFAS) is a persistent problem in many industries, including upstream oil and gas. In this Q&A, remediation expert Grant Scott presents the trouble with these “forever chemicals” and the mitigating efforts being used.

The solvent-based technology involves a modular treatment process that uses a proprietary catalyst designed to safely and sustainably remove hydrogen sulfide (H₂S) from sour gas streams using either produced water or an alkaline water as the treating media. -
This paper presents an experiment investigating dissolution of basaltic primary minerals and conditions favorable for secondary phase formation under deep subsurface storage conditions.
-
This study aims to investigate the efficacy of chemical additives strontium chloride and barium hydroxide in accelerating CO₂ trapping mechanisms, their effect on dissolution of carbonate-bearing minerals, and resulting poroelastic changes in the host rock.
-
This study reviews subsurface microbial activity, biomineralization reactions, and mechanisms prevalent for bioremediating wells, stabilizing cements, and increasing trapping during CO₂ injection and storage.
-
Rock sample characterization, widely used in hydrocarbon exploration and production, is emerging as a critical tool for understanding and optimizing subsurface mineral extraction through in-situ leaching.
-
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.
