Soured reservoirs contain hydrogen sulfide (H2S) that can prompt the formation of exotic sulfide scales, leading to fouling that negatively affects the production of oil and gas. The paper examines the mode of precipitation and deposition of lead sulfide (PbS) scale on anti-fouling surfaces for application in oilfield systems.
This CorrCompilation series focuses primarily on equilibrium-formed scales, where an aqueous fluid changes from an unsaturated equilibrium state to a saturated and supersaturated state and then solids may start to form. These types of fouling minerals include alkaline earth salts, silicates, alkaline salts (NaCl), sulfides, and under specific circumstances, metal sulfide salts that form through equilibrium changes. While corrosion product scales are not the subject of this book, the importance of corrosion product layers to the deposition of other scales will be described.
Since this is a CorrCompilation and more than 90 copies of NACE papers are included, the work is published in four volumes. The editor, Wayne W. Frenier, FNACE, provides an extensive introduction to each volume, offering the reader a thorough mix of history, theory, and engineering techniques and methods for addressing scale.
Volume 1: Introduction to Equipment Subject to Inorganic Scale
Volume 2: Current Mechanisms for Understanding Inorganic Scale Formation and Deposition
Volume 3: Chemistry and Application of Scale Inhibitors
Volume 4: Alternative Methods of Scale Control
This volume, “Chemistry and Application of Scale Inhibitors,” will describe current scale inhibitor (SI) chemicals and theories of their modes of action. These chemicals are used to inhibit (reduce) the detrimental effects of mineral scales on oil and gas as well as other industrial surfaces.
