A method for NMR measurements on borehole materials, e.g., sidewall cores, is based on performing a standard measurement in substantially homogeneous magnetic fields with a sensitivity volume covering an entire sample and a measurement on a fragment of the sample (local measurement), the fragment having a predetermined volume independent of the irregularities of the sample shape (e.g., irregular shaped edges). The fragment of the sample is selected using a switchable static magnetic field gradient or a localized radio-frequency magnetic field. The homogeneous and the local measurement data are processed jointly to obtain volume normalized NMR relaxation data (in porosity units), the processing also using a calibration sample data. A measurement apparatus with an automated sample transfer can be used to implement the method in order to perform high-throughput NMR relaxation measurements that do not require independent measurement of the sample volume.

Tools and methods are used to determine the oil, water, and solids volume fractions in a drilling fluid at the rig site. The volume fractions can be determined in-line with returned drilling fluid by using an NMR magnet and a flow line or sample chamber that receives a fluid sample and loads it into the NMR magnet. Using an RF probe, spectrometer, and computing device, data processing and interpretation of NMR data from the spectrometer is performed, while also raising a flag when iron contamination exceeds a predefined threshold.

Embodiments described herein generally relate to systems, tools, and methods for flow assurance monitoring within pipe structures. In an embodiment is provided a method of determining at least one property of a mixture flowing through a system that includes introducing an inhibitor to a fluid flowing through the system to form the mixture; exposing the mixture to electromagnetic energy to induce at least one paramagnetic response from at least one diamagnetic species present in the mixture flowing through the system; performing electron paramagnetic resonance (EPR) spectroscopy on the at least one paramagnetic response to generate an EPR spectrum; and determining the at least one property of the mixture based on the EPR spectrum. Apparatus for determining fluid properties and systems for extracting hydrocarbons from a subterranean reservoir are also provided.

An NMR apparatus having a magnet system for generating a homogeneous static magnetic field B.sub.0 along a z direction, with a sampling head (1) comprising an RF transmitting and receiving coil system (2) and an opening (3) extending in the z direction for receiving a sample tube (4) containing a sample substance to be analyzed by means of NMR measurement, a compensation element (5) being present which at least partially compensates for disturbances in the homogeneous magnetic field B.sub.0 due to the sample substance and the material of the sample tube at the sample end of the sample tube that protrudes farthest into the sampling head during measuring operation, is characterized in that the compensation element is arranged outside the sample tube protruding into the sampling head during measuring operation of the NMR apparatus and in the z direction below the sample end, and is mounted so as to be movable, in particular displaceable, in the z direction. Thus, the compensation element can nestle against the sample tube during operation without problem. In this way, the susceptibility jump and the resulting B.sub.0 field disturbance in the lower region of the NMR-active sample liquid caused by the lower end of the sample tube are effectively minimizable with particularly uncomplicated technical means.

A sample chamber holder for MAS-NMR capable of operating at both low and high pressures. In one example the sample chamber holder is made up of a sample holder body defining a sample chamber therein, a connector configured to operatively statically hold an in situ rotor within the sample chamber; a coupler configured to operatively connect the sampler holder body to a magnetically coupled rotation member. The magnetically coupled rotation member is configured to engage and rotate a sealing cap from an NMR rotor in such a way so as to allow an NMR cap to be alternatively opened or sealed in-situ while the NMR rotor remains statically positioned in an NMR device.
