| 507128000 | Organic component contains phosphorous attached directly or indirectly to carbon by nonionic bonding | 9 |
| 20100029515 | HYDROCARBON FLUIDS AND METHODS OF USING SAME - A new hydrocarbon fluid composition and methods of using the fluid are disclosed. The fluid is comprised of a liquid hydrocarbon, a phosphate ester, an iron or aluminum salt crosslinker, a hydrocarbon foaming agent and a gas. The fluid can be used in many applications. | 02-04-2010 |
| 20100152067 | FRICTION MODIFIER FOR DRILLING FLUIDS - This invention relates to improved lubrication in drilling and completion fluids used in subterrain drilling for oil and gas. The addition of zinc dialkyl dithiophosphate (ZDDP) acts as a lubricant, an enhancer to other lubricants and rate of penetration enhancer. | 06-17-2010 |
| 20110160098 | Hydraulic Fluid Compositions - An aqueous hydraulic fluid composition comprising a first lubricant comprising at least one phospholipid and a second lubricant comprising an alkoxylate salt. The aqueous hydraulic fluid composition contains less than about 20% by weight (preferably none or substantially none) of an oil selected from the group consisting of mineral oils, synthetic hydrocarbon oils, and mixtures thereof. The use of alkoxylate salts provides increased lubricity and also acts as an emulsion stabilizer for the composition. | 06-30-2011 |
| 20120295820 | MANAGEMENT OF CORROSION IN PHOSPHATE BRINES - Phosphate brines are disclosed having reduced corrosive ratings. The phosphate brines include an additive system that reduces the corrosiveness of the phosphate brines compared to the phosphate brines in the absence of the additive system. | 11-22-2012 |
| 20130178399 | GAS HYDRATE INHIBITORS AND METHODS FOR MAKING AND USING SAME - Methods relate to using phosphate and/or nitrate brines to reduce hydrate formation in flowlines under conditions conducive for hydrate formation in the absence of the phosphate and/or nitrate brine. The phosphate and/or nitrate brines may include compatible anti-corrosion additives. | 07-11-2013 |
| 20130303410 | Invert Emulsion Drilling Fluids for Flat Rheology Drilling - An invert emulsion drilling fluid, and a method of drilling with such fluid, having substantially flat or relatively controlled rheology, as demonstrated by the drilling fluid exhibiting little change in its yield point and gel strength across a temperature range of from about 40° F. to about 180° F., and effected with addition of a fatty dimer diamine additive together with an acid and without the addition of organophilic clays or lignites. | 11-14-2013 |
| 20140303045 | Biocidal Systems and Methods of Use - Systems and methods for controlling microbial growth and/or activity in a gas field fluid or oil field fluid are provided, comprising: a) adding a first biocide component to the gas field fluid or oil field fluid in an amount effective to control microbial growth and/or activity; and b) after a delay, adding a second biocide component to the gas field fluid or oil field fluid. | 10-09-2014 |
| 20150072904 | Oil based mud system - Emulsions usable within a wellbore as drilling fluids can be prepared by adding an internal phase to an external phase to form an emulsion base, and adding solid organophilizated mineral structures, a matrix stabilizing agent, a weighting agent, and a secondary stabilizer to the emulsion base. The solid organophilizated mineral structures stabilize the emulsion base and affect the rheology thereof, and the matrix stabilizing agent and the secondary stabilizer can retain the stability and viscosity of the emulsion base in the presence of hydrophilic solids. In addition to use as a wellbore fluid independently, usable emulsions can be compatible with and combined with traditional emulsions to form a mixture usable within a wellbore a drilling fluid. | 03-12-2015 |
| 20150111791 | WEAKLY CONSOLIDATED, SEMI CONSOLIDATED FORMATION, OR UNCONSOLIDATED FORMATIONS TREATED WITH ZETA POTENTIAL ALTERING COMPOSITIONS TO FORM CONGLOMERATED FORMATIONS - Weakly consolidated formations, semi consolidated formations, or unconsolidated formations treated with an aggregating, agglomerating or conglomerating composition, which alters an aggregation or zeta potential of formation surfaces and particulate to increase a maximum sand free production rate of producing formations and increases the injection rate of injection formations. | 04-23-2015 |
