  • Patent number: 8316941
    Abstract: In a method of treating a sandstone-containing formation penetrated by a wellbore, a treatment fluid comprising an aqueous fluid containing a Bronsted acid, a hydrogen fluoride source and an organic acid or salt thereof that is substantially soluble in the aqueous fluid is formed. The treatment fluid contains less than about 2% of fluoride (F?) by weight of the fluid and from 2% or less of sodium (Na+) by weight of the fluid. The treatment fluid is introduced into the formation through the wellbore as a single-stage without introducing an acid-containing fluid preflush into the formation prior to introducing the treatment fluid.

  • Patent number: 7166560
    Abstract: An acid fracturing method is provided in which the acid is generated in the fracture by hydrolysis of a solid acid-precursor selected from one or more than one of lactide, glycolide, polylactic acid, polyglycolic acid, a copolymer of polylactic acid and polyglycolic acid, a copolymer of glycolic acid with other hydroxy-, carboxylic acid-, or hydroxycarboxylic acid-containing moieties, and a copolymer of lactic acid with other hydroxy-, carboxylic acid or hydroxycarboxylic acid-containing moieties. The solid acid-precursor may be mixed with a solid acid-reactive material to accelerate the hydrolysis and/or coated to slow the hydrolysis. Water-soluble liquid compounds are also given that accelerate the hydrolysis. The method ensures that the acid contacts fracture faces far from the wellbore.

  • Patent number: 6569814
    Abstract: The Invention relates to novel fluids and techniques to optimize/enhance the production of hydrocarbon from subterranean formations (e.g., “completion fluids”), in particular, fluids and techniques are disclosed and claimed which remove wellbore damage and near-wellbore damage in the form of coating formed from drilling and production-related operations (“filtercake”); the techniques can be applied either by themselves or in conjunction with other completion operations, such as gravel packing; preferred embodiments are chelating agent and enzyme systems in a viscoelastic surfactant (VES) matrix.

  • Patent number: 6521028
    Abstract: The present invention is directed to methods for preparing quaternary ammonium salts, particularly pyridinium and quinolinium salts. By preparing these salts in a solvent selected from the group consisting of propylene glycols, propylene glycol ethers and mixtures thereof, the production of undesirable by-products and contamination of the product with undesirable solvents are minimized, if not eliminated. Using the preparation methods of the present invention low hazard corrosion inhibitors and aqueous cleaning solutions using these inhibitors may be prepared. In fact, by preparing dodecyl pyridinium bromide in dipropylene glycol methyl ether as the solvent, a particularly desirable corrosion inhibitor characterized by a low toxicity and a high flash point has been prepared. The present invention thus provides the safer corrosion inhibitors and cleaning solutions long sought by industrial cleaning services.

  • Patent number: 5679170
    Abstract: A method and solution for removing iron oxide-containing scale from the interior surfaces of steel vessels. During normal cleaning procedures for internal scale-encrusted steel surfaces of a utility boiler, a reducing atmosphere is maintained, and an aqueous solution containing an about 4:1 to about 9:1 weight ratio of formic acid and citric acid, is placed in dissolving relation to the scale. The high F/C ratios hold more iron in solution than low F/C ratios, especially if the iron is kept in the 2+oxidation state. The ability of the solution to hold dissolved iron is only slightly dependent on pH, so long as pH is maintained below 7.0. An oxidation stage is not required to remove dissolved iron to below 1 ppm from the solution, during waste treatment procedures using lime and NaOH.

An aqueous cleaning solution containing formic acid and at least one carboxylic acid having at least two carbon atoms wherein the weight ratio of formic acid to higher carboxylic acid is greater than about 4:1 is contacted with the scale in the absence of an oxidizing agent. Preferred carboxylic acids are the mono-, di-, hydroxy-, and polyhydroxy-carboxylic acids having from two to six carbon atoms. More preferrably, the aqueous solution includes about 0.5-10.0 percent-by-weight in total of such acids wherein the weight ratio of formic acid to higher carboxylic acid is from about 4:1 to about 9:1, together with an effective amount of an organic acid corrosion inhibitor and, optionally, a scale dissolution accelerating agent. Preferrably, contact is under a reducing atmosphere, at a temperature in the range of about 150.degree.-200.degree. F. and a pH less than 7.
