    摘要： A system and method for measuring fluid flow in a wellbore in an earth formation using time-of-flight (TOF) sensing and remote detection nuclear magnetic resonance (NMR) techniques, by applying a magnetic field to the formation to polarize spins present in a portion of the formation, providing an encoding shell in the formation, selecting an encoding volume from the encoding shell, applying an encoding signal to excite the spins in the encoding volume, introducing a time delay to the encoding signal, providing a detection shell in the formation, applying a detection signal to the detection shell, detecting an NMR signal generated by the migration of spins from the encoding shell to the detection shell, and collecting TOF data corresponding to time elapsed from when a spin is encoded to when the spin reaches the detection shell.

    摘要： Systems and methods for magic angle spinning nuclear magnetic resonance analysis of samples from unconventional reservoirs are described. Fast and inexpensive methods are described that can provide reliable information on TOC content, type, and maturity (via the relative abundances of different hydrocarbons, for example) without the need for more extensive sample preparation or destruction. If care is taken during sample recovery and storage, NMR can also yield an estimate of gas-in-place, including detailed typing (e.g. methane vs. ethane). The described MAS NMR analysis is used to determine various properties of unconventional reservoirs, including gas and oil shales, which are useful in evaluating their worth and producibility.

    摘要： Methods and related systems are described for use with hydraulic fracturing and other oilfield applications. A tool body is positioned in a wellbore at a location near a subterranean rock formation being fractured. The tool body contains a plurality of deployable continuous fibers. At least some of the deployable continuous fibers are deployed into fractures within a subterranean rock formation. Each deployed fiber is continuous from the tool body to the rock formation. The number of deployable continuous fibers provides sufficient redundancy to make at least a target measurement relating to the fracturing process.

    摘要： A method for the determining a nuclear magnetic resonance characteristic of earth formations surrounding a borehole, includes the following steps: providing a logging device that is movable through the borehole, the logging device having a longitudinal axis; providing a first coil, in the logging device, for generating a magnetic field in the formations; providing a second coil in the logging device; applying a polarizing signal to the first coil; detecting, with the second coil, magnetic resonance of spins in the formations that are precessing around earth's magnetic field; and providing a third coil in the logging device, the third coil being operative to produce a further magnetic field in the borehole that reduces the contribution of spins in the borehole to the magnetic resonance detected by the second coil.
