| 20090075847 | DRILLING FLUID LUBRICANT AND METHOD OF USE - A method for increasing drilling rates by reducing torque and drag in hostile environments such as high pressure, high temperature, and horizontal wells is provided by adding chemically and thermally inert spherical carbon beads to the drilling fluid. | 03-19-2009 |
| 20090118143 | Methods for Manipulation of the Flow of Fluids in Subterranean Formations - A method of treating a subterranean formation penetrated by a wellbore to mitigate the production of unwanted fluids from the wellbore is carried out by forming a treatment fluid containing at least one of an oil-wetting or water-repelling surfactant and a carrier fluid. The treatment fluid is then introduced into the wellbore. The treatment or treatments may be performed remedially or prophylacticaly. The treatment may include the completion and production of zones containing the undesirable fluid(s) and the deliberate formation of cones therein. | 05-07-2009 |
| 20090170731 | CONDUCTIVITY ENHANCING STRUCTURES FOR USE WITH PROPPANTS IN OIL AND GAS WELLS - A mixture of proppant particles and conductivity enhancing structures is disclosed. The spherically shaped proppant particles have convex surfaces. The conductivity enhancing structures include concave surfaces. The proppant particles' convex surfaces abut the conductivity enhancing structures concave surfaces. | 07-02-2009 |
| 20100069270 | Energy Recovery and Reuse for Gel Production - The present disclosure relates to systems and methods for producing a fracturing gel using a preheated hydration fluid. The hydration fluid can be preheated using heat energy recycled from a different part of the operation. Recycling the heat energy can, in certain instances, reduce gel production costs and gel hydration times while improving gel yield. | 03-18-2010 |
| 20100125044 | TREATMENT OF GAS WELL HYDROFRACTURE WASTEWATERS - A method of treating a wastewater is provided and can be used, for example, to treat a gas well hydrofracture wastewater. The method can involve precipitating barium as barium sulfate, precipitating calcium and strontium as calcium carbonate and strontium carbonate, precipitating magnesium hydroxide, and filtering out the metal compounds to form a recycle water. The recycle water produced from the method is also provided, as is a method for using the recycle water as a gas well hydrofracture water. In some embodiments, discharge water from a coal mine, and/or water from an abandoned coal mine, is used as a source of sulfate ions to precipitate barium as barium sulfate. | 05-20-2010 |
| 20100234247 | Gel assisted separation method and dewatering/desalting hydrocarbon oils - A method for separating polar hydrocarbon compounds from a hydrocarbon oil containing polar hydrocarbon compounds comprising the steps of:

| 20120295822 | System and Process for Production of Polyethylene and Polypropylene - A method for introducing inhibitor into a fluid to be treated, the method including forming a dispersion comprising droplets, particles, or gas bubbles of inhibitor dispersed in a continuous phase of a carrier, wherein forming the dispersion comprises subjecting a mixture of the inhibitor and the carrier to a shear rate of greater than about 20,000 s | 11-22-2012 |
| 20130053284 | Modular Roller Oven and Associated Methods - A housing may include a test cell being enclosed and having at least one test cell wall and one sealable opening and has a cell central axis defined along the center line of the length of the test cell, a thermal element in thermal communication with the test cell, and an insulation, at least a portion of the insulation being disposed about the test cell and the thermal element. An apparatus may generally include a housing, a drive connection, and a shaft operably connected to the test cell and extending parallel to the cell central axis from the test cell through the insulation to the drive connection to which the shaft is operably connected. Testing a sample in the test cell of an apparatus operably connected to a driving mechanism may generally include at least manipulating the test cell and analyzing the sample. | 02-28-2013 |
| 20130288934 | Composite Solids System to Prepare Polymer Solutions for Hydraulic Fracturing Treatments - A method of reducing the cost and environmental impact of chemicals used in hydraulic fracturing is to use multiple chemicals that are pre-mixed and then formed into a single solid blended mixture. By forming at least two chemicals into a single solid mixture, the complexity involved in transporting multiple solid or liquid chemicals is avoided. If the solid chemicals were merely premixed they would tend to segregate during shipping, handling, and storage altering the concentration of the chemical mix as it is pumped downhole. Simply having less equipment on the wellsite increases the accuracy of the well treating process and decreases the likelihood of a time consuming and thus costly delay due to equipment failure. | 10-31-2013 |
| 20150024976 | Predicting Properties of Well Bore Treatment Fluids - Methods and systems for predicting properties of well bore treatment fluids are disclosed. An embodiment includes a method of predicting fluid properties comprising: determining an operational window for a well bore fluid system; collecting data at vertices of the operational window; and developing a model comprising predicted properties for a plurality of data points within the operational window, wherein developing the model uses Barycentric interpolation. | 01-22-2015 |
| 20150065401 | FUNCTIONALLY GRADIENT COMPOSITE ARTICLE - A composite downhole article is disclosed. The article is selectively corrodible in a wellbore fluid. The article includes at least one corrodible core member comprising a metallic first material that is corrodible in a wellbore fluid at a first corrosion rate. The article also includes at least one outer member disposed on the core member and comprising a second material that is corrodible in the wellbore fluid at a second corrosion rate, wherein the corrodible core member has a composition gradient or a density gradient, or a combination thereof, and wherein the first corrosion rate is substantially greater than the second corrosion rate. | 03-05-2015 |
