Oil thinning compositions and retrieval methods

摘要

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.

1. A method to recover oil from an oil well, comprising the steps of: a) providing a formulation comprising: D-limonene, soy methyl esters, and glycol ether esters, said formulation lacking oil distillates and water; b) introducing a first portion of said formulation into said oil well; and c) recovering a mixture from said oil well, said mixture comprising at least a portion of said formulation and oil from said oil well.
