507134000 | Organic component contains sulfur attached directly or indirectly to carbon by nonionic bonding | 6 |
20080234145 | Use of Lithium Salts of Fatty Alcohol Sulphates for Cleaning Boreholes, Boring Devices and Borings - The invention relates to the use of compounds of general formula (I): R—O—SO—Li | 09-25-2008 |
20100267592 | Multi-Component Drilling Fluid Additive, and Drilling Fluid System Incorporating the Additive - Multi-component additive for incorporation into a drilling fluid, and a drilling fluid system comprising said multi-component additive. The additive preferably comprises three primary components: (1) a rate of penetration enhancer, namely one of a number of synthetic (non-toxic) ester-based or olefin-based oils as a carrier for other additives, such as surfactants; (2) a lubricant, namely one or more of a number of chlorinated waxes, chlorinated olefins, and plant based fatty acids; and (3) a clay inhibitor/stabilizer, such as a polyglycol. Preferably, the three components are pre-mixed in a single container, for ease in use in adding to a drilling fluid system. The additive may be incorporated into a drilling fluid system at a shore based facility, and the “liquid mud” transported to a drilling rig; or the additive may be brought to the drilling rig and incorporated into a drilling fluid system on site. | 10-21-2010 |

507135000 | Organic component contains a sulfur attached directly to carbon by nonionic bonding (e.g., sulfonate, etc.) | 3 |
20100016180 | Method of Increasing Lubricity of Brine-based Drilling Fluids and Completion Brines - The lubricity of a drilling fluid or a completion fluid may be increased by incorporating into the fluid a water-soluble or water-dispersible salt of a sulfonated (sulfated) vegetable oil or a derivative thereof, such as a sulfonated (sulfated) castor oil. Suitable derivatives include the sodium, potassium, calcium, magnesium or ammonium salt. A non-ionic or anionic surfactant which is capable of enhancing the solubility of the salt may further be incorporated into the drilling fluid or completion fluid. | 01-21-2010 |
20120220502 | COMPOSITIONS COMPRISING ALKYLALKOXYSULFONATES FOR THE PRODUCTION OF HIGH TEMPERATURE STABLE FOAMS - The present invention is directed to the use of alkylalkoxysulfonates for the production of foams, which are stable at high temperatures, e.g. up to about 250° C. Furthermore, the invention relates to a method for producing of high temperature stable foams by using a foamable aqueous composition comprising at least one linear alkylalkoxysulfonate. | 08-30-2012 |
20150065399 | Methods and Compositions for Enhanced Acid Stimulation of Carbonate and Sand Stone Formations - An operations fluid is provided for treatment operations on wellbores associated with hydrocarbon production, the operations fluid comprising: water, an inorganic primary acid; and an alkyl acid surfactant. The alkyl acid surfactant has the general formula {R—X}, wherein R comprises at least one of linear and branched alkyl and alkyl aryl hydrocarbon chains and X comprises an acid, and X may comprise an acid selected from the group comprising sulfonic acids, carboxylic acids, phosphoric acids, and mixtures thereof. The alkyl acid may include an acid selected from the group consisting of alkyl or alkyl aryl acids. The operations fluid may be useful in treatment operations related to formation stimulation or mitigation of non-aqueous filter cakes (NAF) and/or formation invasion by NAF drilling fluids. | 03-05-2015 |
