Abstract: A petrophysically regularized time domain nuclear magnetic resonance (NMR) inversion includes using an NMR tool to acquire NMR data and inverting the acquired NMR data in a time domain using petrophysical constraints. The inverted NMR data is analyzed. The petrophysical constraints may be identified by: determining a number of porobodons to seek, defining a plurality of zones in which only a subset of porobodon sets is present, and stacking all NMR echoes in each zone satisfying discriminators. The number of porobodons to seek may be based on knowledge of core samples, logs, and NMR sensitivity. The discriminator logs may be logs sensitive to porosity partitioning. A computing system having a processor, a memory, and a program stored in memory may be configured to perform the method. The system may be conveyed downhole on a wireline, a while-drilling drill string, a coiled tubing, a slickline, or a wired drill pipe.

Abstract: Asphaltene content and its spatial distribution in a reservoir containing crude oil is an important factor in determining the potential for formation damage and pipeline impairment, as well as planning for processing and refining of the oil. Exemplary uses include: reservoir modeling, development and depletion planning, pressure maintenance, and surface facilities management. A convenient method has been developed which uses two-dimensional NMR techniques during a temperature and/or pressure cycle to quantify the asphaltene content of the crude oil without the need for extracting the oil from the reservoir rock. The technique can be applied to core, down-hole logs, or, a combination of both.

Abstract translation: 岩石物理正则化的时域核磁共振（NMR）反演包括使用NMR工具获得NMR数据并且使用岩石物理学约束在时域反转获取的NMR数据。 分析反相NMR数据。 岩石物理学约束可以通过以下方式来确定：确定多个孔体以寻找多个区域，其中仅存在孔体组的子集，并且在满足鉴别器的每个区域中堆叠所有NMR回波。 要寻求的孔洞数量可能是基于核心样本，原木和核磁共振敏感性的知识。 鉴别器日志可能是对孔隙度划分敏感的日志。 具有处理器，存储器和存储在存储器中的程序的计算系统可以被配置为执行该方法。 该系统可以在电缆，同时钻井钻柱，盘管，钢丝绳或有线钻杆的井下传送。
