Paper Number: SPE-22781-MS
... of analysis have been developed for the determination of treating chemicals in oilfield water systems. Part 1 describes a xenon flash photometer (XFP) that was designed for on-line measurements under harsh, oilfield conditions. The instrumentation is capable of absorption and fluorescence measurements...

... permeability 3 . The oil-in-water emulsion, or so-called reverse emulsion, is produced in all SAGD operations. Despite the variations of the treating systems, chemicals are always required to resolve this reverse emulsion, i.e., to give dry oil that meets the pipeline specifications and preferably oil-free...

... that supply water quality must be carefully controlled in polymerflooding, in- cluding control of bacteria, corrosion, and dissolved oxygen. The cost of treating was estimated at $100,000 per year for water treating chemicals (ap- proximately $0.43/bbl water injected). This cost was assumed to apply to fresh...

.... Due to the short tool body design, it can be used on straight, deviated or horizontal production wells, on injection wells, or on water source wells. The HyperScratcher tool is also considered to treat wells in an ‘SB-4 friendly’ manner, as low volumes of treating chemicals can be pumped through...
