Abstract: Implementations described and claimed herein provide systems and methods for determining surfactant impact on reservoir wettability. In one implementation, a nuclear magnetic resonance T1 measurement of a sample is obtained before surfactant imbibition is applied to the sample, and a second nuclear magnetic T2 measurement of the sample is made after forced imbibition of the surfactant. Moreover, another nuclear magnetic resonance T1 measurement (e.g., omitting surfactant imbibition) can be obtained simultaneously with the nuclear magnetic resonance T2 measurement using a twin core sample. The nuclear magnetic resonance T1 measurement and the nuclear magnetic resonance T2 measurement are captured under simulated reservoir conditions. A fluid typing map is generated using the nuclear magnetic resonance T1 measurement and the nuclear magnetic resonance T2 measurement. An impact of the surfactant on fluid producibility is determined based on the fluid typing map.

Abstract: System and methods for nuclear magnetic resonance (NMR) fluid substitution are provided. NMR logging measurements of a reservoir rock formation are acquired. Fluid zones within the reservoir rock formation are identified based on the acquired measurements. The fluid zones include water zones comprising water-saturated rock and at least one oil zone comprising rock saturated with multiphase fluids. Water zones having petrophysical characteristics matching those of the oil zone(s) within the formation are selected. NMR responses to multiphase fluids resulting from a displacement of water by hydrocarbon in the selected water zones are simulated. A synthetic dataset including NMR T2 distributions of multiphase fluids is generated based on the simulation. The synthetic dataset is used to train a machine learning (ML) model to substitute NMR T2 distributions of multiphase fluids with those of water. The trained ML model is applied to the NMR logging measurements acquired for the oil zone(s).

Erfindungsgemäß ist dabei vorgesehen, dass der Magnetkern (20) zumindest ein zwischen zwei Zuständen schaltbares magnetisches Potentiometer (32) aufweist. Dabei weist das magnetische Potentiometer (32) in einem ersten Zustand einen ersten magnetischen Widerstand auf und das Sensorelement (10) ist in dem ersten Zustand des magnetischen Potentiometers (32) auf eine Messung an einem Spinresonanz-Merkmal eines in den Luftspalt (24) eingebrachten Datenträgers eingerichtet. Das magnetische Potentiometer (32) weist in einem zweiten Zustand einen zweiten, unterschiedlichen magnetischen Widerstand auf, und das Sensorelement (10) ist in dem zweiten Zustand des magnetischen Potentiometers (32) auf eine Zerlegung des Magnetkerns entlang des Zerlegespalts (30) eingerichtet.

Abstract: A method includes screening heterogeneity of a rock sample using nuclear magnetic resonance testing to determine a composition of the rock sample, drilling at least one smaller rock sample representative of the determined composition, and testing the at least one smaller rock sample with mercury- injection capillary pressure to obtain a. capillary pressure distribution (52) of the at least one smaller rock sample. The method further includes decomposing a T2 distribution (54) from the nuclear magnetic resonance testing and the capillary pressure distribution (52) using Gaussian fitting to identify multiple pore systems (58, 50, 59), where the small ends (51, 53) of the Gaussian fitted T2 distribution (54) and the Gaussian fitted, capillary pressure distribution (52) are overlapped for at least one of the identified pore systems (50).

Abstract: Some embodiments provide a method for magnetic resonance imaging of polysaccharide molecules, that includes providing a magnetic field that is sufficiently homogeneous over an imaging volume, generating a spatial encoding in the magnetic field, and acquiring one or more water proton signal intensity measurements at each of multiple voxels within the imaging volume. The signal intensity measurements are acquired at one or more irradiation frequencies at lower parts-per-million (ppm) than a baseline frequency associated with free water protons. The method includes generating, based on the water proton signal intensity measurements in each voxel, a water proton signal intensity map of the relayed Nuclear Overhauser Effect (rNOE) exchange process of aliphatic protons in the polysaccharide molecules to free water protons in the imaging volume, and generating, using a calibration of the water proton signal intensity measurements for the rNOE exchange process, a concentration map of the polysaccharide molecules in the imaging volume.
