20160001614 | SELF-ADAPTIVE METHOD FOR ASSISTING TIRE INFLATION - A self-adaptive method for assisting tire inflation enables control of tire inflation. If the vehicle stops, the central unit of a TPMS (Tire Pressure Monitoring System) can change in a self-adaptive manner from the reception configuration of the “moving” mode at a high bit rate to a “stationary” mode at a low bit rate. At the same time, if there is a variation in the pressure of a tire, the corresponding wheel unit is set for transmission in “stationary” mode at a low bit rate. The power Pa received at the central unit varies according to a curve ( | 01-07-2016 |

20100307747 | ENGINEERED FIBERS FOR WELL TREATMENTS - Mixtures of fibers and solid particles are effective for curing fluid losses and lost circulation in a subterranean well. Stiff fibers are more effective than flexible ones; however, mixtures of stiff and flexible fibers have a synergistic effect. The quantity and particle-size distribution of the solids are optimized according to the stiffness, dimensions and concentrations of fibers. | 12-09-2010 |
20110005758 | METHOD AND COMPOSITION FOR CURING LOST CIRCULATION - The invention provides a system made of fibers and a material able to stick fibers in a network when activated, such activation can be temperature or pH change. The invention preferably is used in a well and as a method to cure lost circulation. | 01-13-2011 |
20110024113 | VISCO-ELASTIC SURFACTANT SPACERS - A spacer for use in an oil well cementing operation comprises an aqueous solution of a visco-elastic surfactant. A method of treating a well in a cementing operation, comprises pumping the spacer into a well ahead of a cement slurry for cementing the well. | 02-03-2011 |
20110048720 | METHODS FOR SERVICING SUBTERRANEAN WELLS - Methods for controlling lost circulation in subterranean wells, and in particular, fluid compositions and methods for operations during which the fluid compositions are pumped into a wellbore, enter voids in the subterranean-well formation through which wellbore fluids escape, and form a seal that limits further egress of wellbore fluid from the wellbore. The methods include preparing a carrier fluid containing compressed expandable foam that may be encapsulated. The carrier fluid is then placed into a lost-circulation zone, whereupon the foam expands to form a barrier that minimizes or blocks further ingress of carrier fluid. Lost-circulation control may be supplemented by introducing additional lost-circulation materials, pumping a cement slurry behind the foam-containing carrier fluid or both. | 03-03-2011 |
20110139454 | Method for Providing Thixotrophy to Fluids Downhole - A method of providing thixotropy to a fluid downhole comprising: adding an encapsulated thixotropic agent to a fluid at the surface; introducing the fluid into a borehole; and subjecting the fluid to a shearing action so as to release the thixotropic agent into the fluid. | 06-16-2011 |
