Abstract: Nuclear magnetic resonance (NMR) method, system, and sensing device for downhole measurements. The NMR device for characterizing a subterranean zone includes a tool body, a magnetic element, and a radio frequency coil. The tool body includes an uphole end and a downhole end, where a longitudinal axis extends through the uphole end and downhole end. The magnetic element is located within the tool body and generates a static magnetic field (B0) in a longitudinal direction at a region of the subterranean zone. The radio frequency coil is located within the tool body and generates a radio frequency magnetic field (B1). The magnetic element and the radio frequency coil enable a side-looking NMR mode.

Abstract: Systems, methods, and software for predicting total organic carbon (TOC) values are described. A representative method includes obtaining nuclear magnetic resonance (NMR) data and training a radial basis function (RBF) model based on the NMR data and measured total organic carbon (TOC) values. The method also includes obtaining subsequent NMR data and employing the trained RBF model to predict TOC values based at least in part on the subsequent NMR data. The method also includes storing or displaying the predicted TOC values.

Abstract: A nuclear magnetic resonance (NMR) logging method includes providing a hybrid pulse sequence having a saturation pulse, an inversion pulse, and a detection sequence. The method also includes measuring echo signals in response to the hybrid pulse sequence. The method also includes deriving a spin-lattice time constant (T1) distribution from the measured echo signals. A NMR system includes a hybrid pulse sequence module to provide a hybrid pulse sequence with a saturation pulse, an inversion pulse, and a detection sequence. The NMR system also includes a control module to select a time interval between the saturation pulse and the inversion pulse.

Abstract: Systems, methods, and software for estimating the viscosity of a subterranean fluid based on NMR logging data are described. In some aspects, a viscosity model relates subterranean fluid viscosity to apparent hydrogen index. An apparent hydrogen index value for a subterranean region is computed based on nuclear magnetic resonance (NMR) logging data acquired from a subterranean region. A subterranean fluid viscosity value is computed for the subterranean region based on the viscosity model and the apparent hydrogen index value.

Abstract: In some aspects, a downhole nuclear magnetic resonance (NMR) tool includes a magnet assembly and an antenna assembly. The NMR tool can operate in a wellbore in a subterranean region to obtain NMR data from the subterranean region. The magnet assembly produces a magnetic field in a volume about the wellbore. The antenna assembly produces excitation in the volume and acquires an azimuthally-selective response from the volume based on the excitation. The antenna assembly can include a transversal-dipole antenna and a monopole antenna.
