20080315873 | Method and Apparatus for Measuring Free Induction Decay Signal and Its Application to Composition Analysis - A method to obtain a free induction decay signal using includes inducing a static magnetic field in a sample volume. A radio frequency (RF) magnetic field is then induced in the sample volume. The RF magnetic field has parameters selected to minimize the contribution of inhomogeneity to the static magnetic field to a free induction decay time. The free induction decay signal is then detected from the sample volume. In one example, prior to inducing the RF magnetic field, a reorienting radio frequency magnetic field is induced in the sample volume to reorient magnetic spins by a first selected angle. The inducing the RF magnetic field in this example has parameters selected to reorient spins by a second angle. The inducing the RF magnetic field and detecting the free induction decay signal are repeated until nuclear magnetic equilibrium is substantially attained. | 12-25-2008 |
20090004748 | Method and Apparatus for Analyzing a Hydrocarbon Mixture Using Nuclear Magnetic Resonance Measurements - A method and apparatus to determine the fractional amount of at least one constituent of a hydrocarbon mixture, comprising dissolving the hydrocarbon mixture in a substantially hydrogen free solvent to produce a diluted solution, the diluted solution having sufficient solvent to render a NMR property of the diluted solution to be predictably related to the constituent concentrations of the hydrocarbon mixture; making NMR measurements on the diluted solution; and determining the fractional amount of at least one constituent of the hydrocarbon mixture from the NMR measurements. | 01-01-2009 |
20090128144 | High Pressure/High Temperature Magnetic Resonance Tool - The present invention pertains to an apparatus and method for conducting magnetic resonance measurements on fluids at high pressures and/or high temperatures. The apparatus can be used in conjunction with or as part of a downhole fluid sampling tool to perform NMR measurements on fluids withdrawn from petroleum reservoirs, or can also be used for laboratory measurements on live reservoir fluids. The apparatus can perform all of the measurements made by modern NMR logging tools, including multi-dimensional distribution functions of spin-spin (T | 05-21-2009 |
20090219019 | DOWNHOLE MICRO MAGNETIC RESONANCE ANALYZER - A downhole micro MR analyzer for use in a wellbore, having a micro sample tube, a micro RF coil in close proximity to the micro sample tube, and one or more magnets disposed about the micro sample tube is disclosed. The micro MR analyzer can be used for nuclear magnetic resonance or electron spin resonance experiments to ascertain formation properties and chemical compositions. | 09-03-2009 |
20140253116 | SYSTEM AND METHOD FOR OBTAINING NUCLEAR MAGNETIC RESONANCE MEASUREMENTS ON RESERVOIR FLUIDS FOR PREDICTION OF FLUID PROPERTIES - A nuclear magnetic resonance (NMR) measurement system for high pressure and temperature measurements on fluids is disclosed. The system has a sensor assembly that includes a sample holder having a body formed from a non-magnetic metal and defining an interior cavity for receiving a fluid sample, a frame member disposed in the interior cavity of the sample holder, an antenna coil disposed in the interior cavity about the frame member, an inlet that allows the fluid sample to enter the interior cavity, an outlet that allows for the fluid sample to be flushed from the interior cavity, and a magnet assembly having a central bore in which the sample holder is disposed. Adjacent to the sample holder are pulsed field gradient coils for performing diffusion measurements. The system further includes pulse sequencer circuitry that supplies signals to the antenna coil. When the interior cavity of the sample holder is filled with the fluid sample, the antenna coil and the frame member are at least partially submerged in the fluid sample, and the antenna coil obtains NMR measurements of the fluid sample in response to the signals. Related methods and apparatuses are also disclosed herein. | 09-11-2014 |

20110040857 | Automated Services Procurement Through Multi-Stage Process - A system which enables a secure network boot to address customer services offerings. The customer service offerings can include on-demand diagnostics to system reinstallation as well as automatic entitlement validation and service installation. Such a system enables a method of network booting that can be secure from beginning to end, is routable in any network configuration that supports Internet routing, avoids traditional infrastructure requirements thereby making the infrastructure more accessible, is extensible to address scaling requirements, is extensible to EFI technology and can be used on existing BIOS option-ROM implementations, provides a better (i.e., simpler, more secure) customer experience for network boot services, provides a multi-stage architecture that allows numerous service offerings to be obtained once entitlement is validated, and provides for both In-Band (OS operational and booted) and Out-of-Band (OS not operational or not installed) access to remote service capabilities. | 02-17-2011 |
20110191863 | System and Method for Identifying Systems and Replacing Components - A system, method, and computer-readable medium are disclosed for managing a system's entitlement to digital assets when the system's components are replaced. A unique system identifier, comprising the unique identifiers of predetermined system components, is associated with digital assets data to generate digital assets entitlement data, which in turn entitles the system to process the digital assets data. The digital assets entitlement is perpetuated when a first unique system component identifier is replaced with a second unique system component identifier. | 08-04-2011 |
