The petroleum engineer is often at the mercy of the chemical manufacturer when deciding which products to use during which phase of the production operation. However, choosing the wrong chemical could lead to cost overruns and a serious loss in production. This book provides petroleum engineers with the necessary information for selecting and application of oil field chemicals. Condensed for readability, this manual provides users with information on oil field chemicals such as drilling muds, corrosion inhibitors gelling agents, scale inhibitors, and bacteria control. The manual also includes cutting edge chemical and polymers such as water soluble polymers, viscosity control - enhanced, microencapsulation, thickeners, recycling additives, lubrication, surfactants, workover and completion fluids, surfactants for flooding techniques, environmental protection chemicals, and green chemicals alternative construction materials.
