Oilfield chemistry
This paper presents a novel methodology for assessing the rapid mineral carbonation of carbon dioxide through geochemical interactions with carbon-, magnesium-, and iron-rich minerals abundant in geological formations.
This study contributes to enhancing the understanding of scale-inhibitor retention in rock formations.
This paper details 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.

The application of an extended-release scale-inhibitor in approximately 70 vertical conventional wells in the Permian Basin has shown approximately three times better performance compared to the incumbent chemical. -
This latest project will build on a previous initiative with up to a trio of field trials aimed at supporting regulatory authorities and industry to establish new standards and practices for the use of online oil-in-water analyzers at remote locations.

With an eye to the future, Interface Fluidics is bringing nanotech to the oil field.
-
S13Cr tubing specimens experienced stress corrosion cracking with phosphate-based completion fluids contaminated with mud and oxygen, whereas formate-based completion fluid is compatible with the tubing.

The featured papers and suggested further reading summarize the current SPE literature state of the art for H2S scavenger research and development and have been selected to give readers a broad indication from both academia and industry around the world.
-
This paper describes studies that confirm that enzyme-based, environmentally preferable chemistries can be used to break polymers and mitigate H2S in various systems.
-
The source of gummy, damaging polymer gunk that has flowed from Oklahoma oil wells is becoming clear, and one of the lessons learned is that shale plays require petroleum engineers to learn more about chemistry.
-
In an era where capital markets are hitting the brakes on funding the US shale sector, operators have increasingly pivoted from production growth to maximizing the rates of return via lower-cost wells.
-
The complete paper highlights examples of nonmetallic materials selection and qualification for upstream water-injection and producer and hydrocarbon wells and presents suggestions for future progress.
-
The complete paper discusses the importance of adequate preparation and the approaches used to overcome challenges of EOR operations, including handling back-produced polymer.
