The present invention discloses a diffusion edited pulse technique that allows information about a fluid to be extracted, comprising: a) obtaining a fluid sample; b) generating a sequence of magnetic field pulses in the fluid, the sequence comprising an initial magnetic field pulse, a first portion that follows the initial magnetic field pulse, and a second portion that follows the first portion; c) detecting magnetic resonance signals using the second portion of the sequence; d) modifying the first portion of the sequence, and repeating steps (b) and (c); and e) extracting information about the fluid by determining relaxation and diffusion characteristics and their correlation based on the signals detected in steps (c) and (d). Also disclosed is a logging tool equipped with a processor to implement the diffusion edited pulse technique.

Systems and methods for improved acquisition of magnetic field data for magnetic ranging while drilling are provided. In one embodiment, such a system may include a borehole assembly and data processing circuitry. The borehole assembly may include an electric current driving tool configured to cause a current to flow across a drill collar of the borehole assembly and an internal magnetometer disposed within the drill collar and between the insulated gap and an end of the borehole assembly, which may be configured to measure magnetic field signals that penetrate the drill collar. The data processing circuitry may be configured to remove all or part of a noise component of the magnetic field signals that arises due to an eccentricity in the drill collar

Small-sized flowlines are provided for use in NMR apparatus. The small-sized flowlines can have a channel with an inner diameter or maximum width of less than 0.2 inch and can be made of sapphire, yttria-stabilized zirconia (YSZ), or extruded polyether ether ketone (PEEK), which are useful in high temperature, high pressure environments such as downhole in a geological formation.

A method and system for detecting an anomaly in measurement data captured by a downhole tool is disclosed provided. In the method and system, measurement data comprising a plurality of measurement channels is obtained and reference data including healthy reference data and faulty reference data is also obtained. The measurement data is preprocessed by modeling at least one measurement channel of the plurality of measurement channels using modeling parameters to produce pre-processed measurement data. Further, a first distance between the pre-processed measurement data and the healthy reference data is obtained and determined to exceed a first threshold for the first distance. A report is generated in response to determining that the first distance exceeds the first threshold. The report indicates detection of the anomaly in the measurement data
