Oilfield chemistry
Field examples from the Bakken Shale and Permian Basin illustrate the benefits of deploying polymer-coated and uncoated scale inhibitors in unconventional wells.
New strategies for protecting metal infrastructure emerge as operators fine-tune a corrosion threat screening process and develop a new method for tracking inhibitor effectiveness.
Interfacial tension keeps oil and water separate by resisting the mixing of their molecules at the surface. Learn how industry experts measure this force to diagnose fluid behavior.

This paper examines the corrosion-inhibiting properties of several edible stems at downhole conditions with high concentrations of hydrochloric acid. The objective is to present an alternative variety of corrosion inhibitors that are environmentally friendly and nontoxic. -
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 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.
-
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 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.
