  • Oil thinning compositions and retrieval methods
    Patent number: 9328284
    Abstract: Compositions of plant oil-based biodegradable crude oil thinning fluids are described having a performance especially suitable to reducing crude oil viscosity in extraction and retrieval operations. A method to recover oil from an oil well is described, comprising the steps of: a) providing a formulation comprising one or more terpenoid compounds, soy methyl esters, and glycol ether esters; b) introducing a first portion of the formulation into an oil well; and c) recovering a mixture from the oil well, where the mixture comprises at least a portion of the formulation together with oil from the oil well.

  • Bituminous substrate removal composition
    Patent number: 6946434
    Abstract: A non-toxic, non-hazardous, environmentally safe composition provides an effective, fast acting cleaning solution for removal of tar, oils, asphalt and other bituminous materials from industrial equipment surfaces. The composition is a mixture of a carrier monocyclic monoterpene and a nonionic surfactant such as an alkylphenol ethoxylate. The mixture is applied directly to surfaces to be cleaned, and rinsed with water in the absence of mechanical intervention.
