| 507267000 | Organic component contains carboxylic acid, ester, or salt thereof | 6 |
| 20090143259 | Particles - Manufactures particles comprising a chemical treatment agent which are useful in wells are provided. The particles have the advantage of being able to chemically treat a well, e.g. to remove filter cake. Embodiments of the invention improve well production by providing sand control and/or increasing permeability of a gravel pack. Methods of using the particles and a gravel pack comprising the particles are also provided. | 06-04-2009 |
| 20090209439 | ACIDIZING TREATMENT COMPOSITIONS AND METHODS - A reservoir treatment fluid is described being a hydrochloric acid and a compound forming a carboxylic acid within a well penetrating a subterranean reservoir. | 08-20-2009 |
| 20100167967 | WELLBORE TREATMENT WITH HYDROCARBON-RESPONSIVE FLUID CONTAINING OLIGOMERIC VISCOELASTIC SURFACTANT - A treatment of a subterranean formation which contains a hydrocarbon-bearing zone, is carried out using a hydrocarbon-responsive fluid thickened with an oligomeric surfactant consisting of from 2 to 8_linked surfactant monomer subunits. The process of treatment comprises

| 20120094878 | Non-Damaging Bimodal Stimulation Composition and Method of use Thereof - A method and apparatus for a bimodal stimulation composition for removal of thickness of a filter cake while minimizing fluid loss is provided. The bimodal stimulation composition includes water, a salt, an acid, and a viscoelastic surfactant. | 04-19-2012 |
| 20140128297 | System and Method for Injecting Peracetic Acid - A method and apparatus for combining multiple sources of intake water for use in hydraulic fracturing and other oil and gas drilling operations and treating the water with peracetic acid prior to discharging into one or more frac tanks or into a well. The apparatus includes a manifold assembly that combines water from multiple sources prior to entering a mixer where PAA is injected in a finely dispersed spray under pressure to thoroughly mix the PAA and intake water prior to be discharged into one or more frac tanks. By using a manifold assembly, the apparatus is easily transported to different job site-locations and permits the use of standard connection fittings to easily connect the apparatus to existing fracturing equipment. A method for injecting the PAA and testing and adjusting the level of PAA is also disclosed. | 05-08-2014 |
| 20160096989 | Olefinic Ester Compositions and Their Use in Stimulating Hydrocarbon Production from a Subterranean Formation - Compositions for stimulating hydrocarbon production from a subterranean formation are generally disclosed. In some embodiments, such compositions include olefinic ester compounds, such as alkyl esters of C10-18 unsaturated fatty acids. In some embodiments, the olefinic ester compounds are derived from a natural oil or a natural oil derivative, for example, by catalytic olefin metathesis. Uses of such compounds, such as in oil- and gas-production methods are also generally disclosed. | 04-07-2016 |
