As Exciting as Watching Scale Grow: Real-Time Observations Generate New Control Ideas
The chemical reactions creating buildups of scale that can clog a well can be replicated in a chemical lab, but researchers are finding many more variables on the surfaces of pipes that need to be considered.
Squeeze Treatments Combat Scale Deposition
At the 2017 SPE Oilfield Chemistry Conference, an assistant professor from Heriot-Watt University discusses the optimization of squeeze treatments delivered by diving support vessels.
Foamer Developed To Help Corrosion, Scale Inhibition
A look at the challenges in creating a foamer with corrosion and scale inhibition properties for application in wet-gas production.
Time-Resolved Fluorescence for Real-Time Monitoring of Scale and Corrosion Inhibitors
This paper describes a novel method of chemical dosage based on time-resolved fluorescence (TRF) that allows a simple, accurate, and efficient quantification of chemicals below parts-per-million ranges, even for double (scale/scale, scale/corrosion) quantification.
Novel Viscosity Reducer Aids Removal of Scale From Electrical Submersible Pumps
Rigless coiled-tubing-unit (CTU) interventions can be effective in returning to production wells that have lost electrical-submersible-pump (ESP) efficiency because of organic, inorganic, or mixed scale deposits.
FeS-Scale Cleanout With High-Pressure Coiled Tubing and Tailored Fluid
The gas-producing carbonate zones of the Ghawar field in eastern Saudi Arabia have been affected by extensive iron sulfide (FeS) scale deposition, reducing overall gas production and increasing risks during well interventions.
Modeling, Monitoring Aid Fight Against Scale in Alkali-Surfactant-Polymer Floods
Two alkali/surfactant/polymer (ASP) floods became operational in the Taber area of Alberta, Canada, in 2006 and 2008.
