Abstract
This invention relates to a paraffin-containing fluid composition comprising a phenolic resin containing one or more calixarene compounds (i.e., a calixarene resin). The invention also relates to methods for dispersing paraffin crystals, inhibiting paraffin crystal deposition, or treating a well or vessel to reduce the deposition of paraffin crystals, with a calixarene resin.
Claims23
A method for dispersing paraffin crystals or inhibiting paraffin crystal deposition in a paraffin-containing fluid, comprising:
- adding to a paraffin-containing fluid an effective amount of a resin comprising one or more calixarene compounds, wherein the resin is at least partially soluble in the paraffin-containing fluid, and wherein the resin disperses the paraffin in the paraffin-containing fluid and/or inhibits the deposition of the paraffin crystals.
A method for treating a well or vessel surface to reduce the deposition of paraffin crystals on the well or vessel surface, comprising:
- treating the well or vessel surface with a resin composition comprising an effective amount of a resin comprising one or more calixarene compounds, wherein the treatment reduces the deposition of paraffin crystals on the well or vessel surface.
A paraffin-containing fluid composition comprising:
- a) a paraffin-containing fluid;
- and
- b) a resin comprising one or more calixarene compounds, wherein the resin is at least partially soluble in the paraffin-containing fluid, wherein the resin disperses the paraffin in the fluid composition and/or inhibits the deposition of the paraffin crystals.
