摘要： A method of obtaining nuclear magnetic resonance (NMR) data from a subterranean formation may include operating a tool in a subterranean formation for generating both NMR data and NMR scaled data based upon NMR measurements of the subterranean formation. The method also includes operating the tool for encoding and transmitting both the NMR data and NMR scaled data, and receiving and decoding, above the subterranean formation, both the NMR data and NMR scaled data from the tool. The method also includes performing error-correction of the received and decoded NMR data based upon the received and decoded NMR scaled data.

摘要： Methods and related systems are described for estimating fluid or rock properties from NMR measurements. A modified pulse sequence is provided that can directly provide moments of relaxation-time or diffusion distributions. This pulse sequence can be adapted to the desired moment of relaxation-time or diffusion coefficient. The data from this pulse sequence provides direct estimates of fluid properties such as average chain length and viscosity of a hydrocarbon. In comparison to the uniformly-spaced pulse sequence, these pulse sequences are faster and have a lower error bar in computing the fluid properties.

摘要： Formation fluid data based on measurements taken downhole under natural conditions is utilized to help identify reservoir compartments. A geological model of the reservoir including expected pressure and temperature conditions is integrated with a predicted fluid model fitted to measured composition and PVT data on reservoir fluid samples or representative analog. Synthetic downhole fluid analysis (DFA) logs created from the predictive fluid model can be displayed along the proposed borehole trajectory by geological modeling software prior to data acquisition. During a downhole fluid sampling operation, actual measurements can be displayed next to the predicted logs. If agreement exists between the predicted and measured fluid samples, the geologic and fluid models are validated. However, if there is a discrepancy between the predicted and measured fluid samples, the geological model and the fluid model need to be re-analyzed, e.g., to identify reservoir fluid compartments. A quantitative comparative analysis of the sampled fluids can be performed against other samples in the same borehole or in different boreholes in the field or region to calculate the statistical similarity of the fluids, and thus the possible connectivity between two or more reservoir regions.
摘要翻译：基于在自然条件下井下测量的地层流体数据用于帮助识别储层隔室。包括预期压力和温度条件在内的储层的地质模型与预测的流体模型相结合，该流体模型适用于储层流体样品或代表性模拟物的测量组成和PVT数据。在数据采集之前，可以通过地质建模软件沿预期钻孔轨迹显示从预测流体模型创建的合成井下流体分析（DFA）日志。在井下流体采样操作期间，可以在预测的日志旁边显示实际测量值。如果预测和测量的流体样品之间存在一致性，则对地质和流体模型进行验证。然而，如果预测和测量的流体样本之间存在差异，则需要重新分析地质模型和流体模型，例如识别储层流体隔室。可以对相同钻孔中的其他样品或场或区域中的不同钻孔中的其他样品进行取样流体的定量比较分析，以计算流体的统计学相似性，从而计算两个或多个储层区域之间的可能连通性。

摘要： Adsorbed gas in a formation may be estimated. Nuclear magnetic resonance (NMR) data for a subsurface geological formation is obtained, and at least a portion of the NMR data is corrected to produce corrected NMR data. A NMR-based estimate of formation porosity is determined using the corrected NMR data. Dielectric permittivity data for the subsurface geological formation is obtained, and a dielectric permittivity-based estimate of the formation water-filled porosity is determined using the dielectric permittivity data. A gas volume is determined using the determined NMR-based estimate of the formation porosity and the determined dielectric permittivity-based estimate of the formation water-filled porosity. The gas volume may be determined by subtracting the determined dielectric permittivity-based estimate of the formation water-filled porosity from the determined NMR-based estimate of the formation porosity. The gas volume per unit volume of the formation may be determined using an equation of state.
