Water-in-Crude oil emulsion stabilized by natural surface active components (such as asphaltene) are one of the major problems in relation to petroleum production.such problems : the corrosion of pipe work pumps production , equipment and downstream overhead distillation columns - the expense of pumping or transporting the water via pipeline or tanker - the problems associated with increased oil viscosity as a consequence of finely dispersed water within crude oil.One of the readily used methods for breaking emulsion is chemical demulsification by surfactants for this reason A new of some...

This book tackles with originality of H2S, Problems and scavenging. the scavenging process is the main object of the production problem companies during all petroleum processes. So that this book discuss the significant dangers and operating problems posed by H2S and creates a better understanding of available mitigation options as well as how those options can be tailored to meet particular needs. Proper treatment of H2S with an appropriate H2S scavenger will improve safety, environmental compliance, product quality and process integrity management.

This book illustrates drilling fluids technology, including drilling problems related to drilling fluids. After a general review of mud types , properties and the currently used additives (density agents , viscosifiers , thinners , filtrate reducing agents , alkalinity control agents , emulsifiers , lubricants spotting fluids , lost circulation materials , shale inhibitors and hydrogen sulfide scavengers) are described followed by drilling problems related to drilling fluids.
