Abstract: A scale inhibition fluid for use in a wellbore comprises a layered double hydroxide (LDH) having a scale inhibitor (SI) intercalated between positively-charged layers thereof. Also disclosed is a scale treatment fluid comprising such an LDH and SI and methods of making and using same. The material can be formed prior to use in a wellbore, formed during a treatment, formed within the wellbore, or the LDH can be recharged within a wellbore by injecting a SI after the material has been in place within the wellbore, or any combination thereof.

Abstract: A method for inhibiting the formation of gas hydrates within a fluid comprising a gaseous hydrocarbon phase, a liquid hydrocarbon phase and an aqueous phase which method comprises mixing a polymeric emulsifier and optionally a non-ionic non-polymeric co-emulsifier with the fluid prior to subjecting the fluid to conditions under which gas hydrates can be formed so as to generate a water-in-oil emulsion comprising a discontinuous aqueous phase, a continuous liquid hydrocarbon phase and a substantially gas impermeable interfacial layer comprising said polymeric emulsifier and optionally said non-ionic non-polymeric co-emulsifier wherein the aqueous phase is distributed in the continuous liquid hydrocarbon phase in the form of droplets and the substantially gas impermeable interfacial layer encapsulates said droplets.
