What is Produced Water?

Produced water is any water that is conveyed to the surface from an oil or gas reservoir during oil and gas production. This water will be from one or more of the following sources: > Connate water which is present in the reservoir prior to production > Condensed water which is condensed from the produced […]

High Impact PVC/Polycarbonate Alloy Compositions

A preferred rigid thermoplastic resin composition having high impact strength and resistance to thermal distortion includes a vinyl chloride resin/polycarbonate alloy and at least 3 parts by weight of butadiene-modified acrylic per 100 parts by weight of the alloy. A particularly preferred thermoplastic resin composition includes the alloy and both butadiene-modified acrylic and ethylene-vinyl acetate […]

Flame Retardant Polypropylene Molding Compositions

Described are polypropylene molding compositions which have surprisingly good physical properties in combination with flame retardancy, which include copolymers represented by the formula: ##STR1## wherein n is >1, P is isotactic or syndiotactic polypropylene, and S is a grafted side chain having brominated monomeric units of the formula: ##STR2## wherein x=1 to 4, R.sub.1 is […]

Low Smoke Intumescent Flame Retardant For Thermoset Composites

The use of a new low smoke intumescent flame retardant for thermoset composites is described. This material, CN-1197 flame retardant, is a phosphorous-based compound which is very effective in promoting an intumescent char on the polymer surface during flammability tests. SUGGESTED CITATION Low Smoke Intumescent Flame Retardant For Thermoset Composites, E. J. Termine and K. […]

Heat Distortion Temperature Modification Of Rigid PVC And Chlorinated PVC: A Method To Produce Low Smoke Compositions

The use of a new low smoke, heat distortion temperature modifier for rigid PVC and chlorinated PVC is discussed. This material, CN-1427, is a tetrabromobisphenol A carbonate oligomer which is compatible with vinyl compositions. The carbonate oligomer can be compounded into PVC resin to improve heat distortion temperature of PVC and CPVC by 20–30°C. Unlike […]

Understanding Chemistry of Clear Brine Fluids … Best Performance

Selecting a Clear Brine Fluid (CBF) for deepwater completion is-or at least should be-a complex process. Impaired production experiences are caused by localized corrosion, stress crack failures of tubing metallurgy or by formation damage, as fluids react chemically with production gases or fluid additives. Besides technical complexity, economics drives operators to seek a thorough understanding […]
