    Abstract: A process for producing a fully cured, infusible coating which when applied to surfaces normally susceptible to the deposition of mineral scale substantially improves the resistance of such surfaces to mineral scale comprising, (1) applying to a substrate whose scale resistance is to be improved an acid or base catalyzed phenolic-aldehyde resin condensate containing a substantial number of reactive hydroxyl groups which are susceptible to oxyalkylation by a base catalyzed reaction with alkylene carbonate; and (2) contacting the resin condensate coated on the substrate with a catalytic quantity of basic catalyst and at least two moles of molten alkylene carbonate per mole of phenolic hydroxyl groups at a temperature ranging from about 350* to 380*F. until the surface of the coated substrate is converted into a surface with substantially improved scaleresistant properties; then (3) curing the resin until it is a fully cured, infusible coating bonded to the noramlly scalesusceptible surface.

    Abstract: Significant improvement in the recovery of hydrocarbons from a subterranean hydrocarbon-bearing formation containing acidsoluble components is accomplished by injecting into the formation via an injection well drilled into a formation communicating with an adjacent producing well and containing acid-soluble components which may or may not have water-sensitive clays and shales included therein, an aqueous acidic solution of a compound as hereinafter described whereupon the acid component reacts with the acid-soluble components of the formation creating passageways or enlarging existing passageways thus facilitating the flow of fluids therein and the compound prevents postprecipitation of dissolved salts and thereby increases the recovery of hydrocarbons from the formation through the adjacent producing well.

    Abstract: Solid paraffin-like hydrocarbon materials derived from petroliferous fluids which have been deposited in hydrocarbonbearing formations are removed by introducing into the formation in the vicinity of the well bore a hydrolyzable, aprotic, halogenated organic material, such as allyl chloride, whereby the said paraffin-like hydrocarbon material is removed, and the permeability and porosity of the formation and production of hydrocarbons therefrom is increased, the well is returned to production and the hydrolyzable, aprotic, halogenated organic compound containing the dissolved or peptized paraffin is removed from the well and conducted to a vessel containing water or a base dissolved in water.

    Abstract: Permeability of a cement pack containing acid-soluble materials in a wellbore traversing a producing formation is improved by the controlled generation in situ of a halogenated acid whereby acid-soluble materials accumulated at the pack face and within the cement pack are dissolved and the flow of fluids therethrough is facilitated, without substantially weakening the mechanical strength of the cement pack.
