  • Compositions and methods for controlling paraffin and asphaltene problems in wells
    Patent number: 10711175
    Abstract: A composition and method for controlling heavy hydrocarbons in down-hole environments and with associated equipment used in oil and gas well operations. The composition and method comprising an ether and optionally an ester, an alkoxylated alcohol or a hydrocarbon co-solvent. The compositions and methods are useful in controlling heavy hydrocarbons such as paraffins and asphaltenes by dissolving paraffins, suspending paraffins and asphaltenes and dissolving heavy oils, both down-hole and with associated equipment.
