20140126330 | COILED TUBING CONDITION MONITORING SYSTEM - A system and techniques for acoustically establishing the onset of an emergent condition relative coiled tubing in a well. The system may include fiber optic line run through the coiled tubing for sake of vibration detection in coiled tubing indicative of buckling, structural defects or other downhole coiled tubing conditions. Thus, application optimization action may be undertaken in a manner that enhances coiled tubing operational efficacy. | 05-08-2014 |
20150101828 | Tube Forming Device - A technique facilitates the plastic deformation of tubing to a desired size and shape. The technique enables deformation of tubing, such as a coiled tubing end, in a manner which facilitates installation of a tubing connector. A tubing forming device is used in cooperation with a tubing injector. The tubing injector moves the tubing through a die of the tubing forming device in a linear direction so as to deform the tubing to a desired shape and/or size. | 04-16-2015 |
20150204177 | DOWNHOLE HETEROGENEOUS PROPPANT - A technique facilitates treatment of a subterranean formation. A proppant and a proppant carrier fluid are delivered to a subterranean location for treatment of the formation. At the subterranean location, heterogeneities of proppant structures are generated with the proppant and the proppant carrier fluid. The heterogeneous proppant structures are then transported into the subterranean formation to improve conductivity. | 07-23-2015 |
20150240148 | HYDRATION SYSTEMS AND METHODS - A substantially continuous stream of aqueous fluid and a substantially continuous stream of gel having a first concentration are combined to form a substantially continuous stream of gel having a second concentration. The second concentration is substantially lower than the first concentration. The gel having the second concentration may thereafter be utilized in conjunction with a well fracturing operation. | 08-27-2015 |
20150293252 | WIRELESS LOGGING OF FLUID FILLED BOREHOLES - A predetermined condition in a fluid-filled wellbore system can be detected by generating at least one sound in the wellbore system in response to the condition, such that a detectable change is created in some characteristic of the emitted sound, and detecting the at least one sound and the change, the detection being indicative that the predetermined condition has occurred. Equipment for facilitating detection of the condition can include a trigger operable in response to the condition; a generator operable to emit sound in the borehole and to create a detectable change in some characteristic of the emitted sound in response to the trigger; and at least one sensor operable to monitor the sound and detect the change, the detection being indicative that the predetermined condition has occurred. It is also possible to estimate a value of a property of a fluid-filled wellbore system. This can be accomplished by recording data including at least one of pressure and rate of flow at one or more locations in the wellbore system, and then estimating the value of the property by employing a model for predicting at least one of pressure and rate of flow dependent upon parameters detailing at least one of wellbore system geometry, viscoacoustic properties of the fluid and entrained solids contained in the wellbore system, locations of boundaries and entrained solids, and characteristics and locations of disturbances to pressure and flow in the wellbore system, in order to determine a best prediction of some attribute of the recorded data. | 10-15-2015 |
20160047184 | WELLSITE MIXER SENSING ASSEMBLY AND METHOD OF USING SAME - A mixer sensing assembly of a mixer for mixing a wellsite fluid in a tank at a wellsite is provided. The mixer includes a shaft driven by a driver and a paddle operatively connectable to the shaft and rotatable therewith. The sensor assembly includes a mount operatively connectable to the shaft, a fluid interface, and a mixing sensor. The fluid interface is responsive to flow of the wellsite fluid passing thereby, and is connectable to the mount. The mixing sensor is connectable to the mount, the fluid interface, and/or the shaft to measure a strain applied to the thereto whereby fluid parameters of the wellsite fluid may be determined. The wellsite fluid may be mixed moving the components in the tank with the mixer, and measuring a strain on the mixer by detecting movement of the sensor assembly. | 02-18-2016 |
20160047185 | WELLSITE MIXING SYSTEM WITH CALIBRATOR AND METHOD OF USING SAME - A mixing system and method for mixing a wellsite fluid including a mixture is provided. The mixing system includes a mixing unit, feed valves, and a calibrator. The mixing unit includes a mixing tank having mixing bins to pass the mixture therethrough, mixers positionable in the mixing tank, and a driver to drive the mixers. The feed valves selectively permit the components to pass into the mixing tank. The calibrator includes a calibrator sensor that connects to the mixers to measure equipment parameters thereof, and a controller connectable to the calibrator sensor and the feed valves to selectively adjust an amount of the components passing into the mixing tank based on the equipment parameters. The method may involve measuring equipment parameters of the mixers during mixing and calibrating by selectively adjusting an amount of the components passing into the mixing tank based on the measured equipment parameters. | 02-18-2016 |
20160103235 | TUBE WAVE GENERATION - A method to generate a tube wave in a tubular system involves reciprocating a plunger in a chamber system to alternatingly increase and decrease net volume, drawing fluid from and returning the fluid to a tubular system and into and from the chamber system, to generate a tube wave, and guiding the tube wave to the tubular system. Also, a tube wave generator-sensor system has a chamber system, a plunger, a driver to reciprocate the plunger within the chamber system to generate a tube wave, a flow passage to guide the tube wave into a tubular system, and a sensor to receive the tube wave signal and/or response from the tubular system. The method and system can work with or without a firing valve and or accumulator, without adding or subtracting fluid from the tubular system. | 04-14-2016 |
