摘要： A method of normalizing well log data relating to geology of a subsurface region includes identifying a pair of markers defining a zone on each well log, determining a statistic for a property within the zone for each well log, fitting a smooth function to the statistics to create a first-iteration trend surface, determining, for each statistic, a deviation from the trend surface and eliminating those statistics that deviate from the trend surface by greater than a threshold value, fitting a smooth function to the remaining statistics to create a second-iteration trend surface, normalizing the property for each well log based on the second-iteration trend surface, and analyzing the normalized properties to determine the geology of the subsurface region.

摘要： A method of automatically interpreting well log data indicative of physical attributes of a portion of a subterranean formation which include some portion of samples with known facies classification to be used as training data, dividing the training data into two subsets, a calibration set and a cross-validation set, using an automated supervised learning facies identification method to determine a preliminary identification of facies in the subterranean formation based on the calibration set, calculating a confusion matrix for the supervised learning facies identification method by comparing predicted and observed facies for the cross-validation set, calculating a facies transition matrix characterizing changes between contiguous facies, and using the preliminary identification, the facies transition matrix, and the confusion matrix, iteratively calculating updated facies identifications.

摘要： A system and a method, implemented on a computer, for calculating property distribution uncertainty of spatially correlated petrophysical data. The method includes inputting, into the computer, a sample petrophysical data comprising correlated data; applying, using the computer, a variogram to the sample petrophysical data to select a plurality of subsets of data, the subsets of data being substantially less correlated than the sample petrophysical data; and applying, using the computer, a bootstrap process on each of the plurality of subsets of data to obtain a plurality of bootstrap data sets from each of the plurality of subsets of data. The method further includes calculating data distributions for each of the obtained plurality of bootstrap data sets; ranking the data distributions by using a selected statistical parameter to obtain ranked data distributions; and characterizing the uncertainty based on the ranked data distributions.

摘要： A system and method, implemented on a computer, for determining the uncertainty of soft-data debiasing of property distributions of spatially correlated reservoir data are provided. The method includes inputting, into the computer, soft-data at a plurality of spatial locations on a grid and hard-data at a plurality of location along well paths that intersect the grid. Each location of the hard-data is collocated with soft-data values of one or more types. The method further includes calculating, using the computer, a variogram of the hard-data and creating subsets of independent hard-data using the variogram and the soft-data values that are collocated with each of the hard-data location; applying, using the computer, a bootstrap process on each of the plurality of subsets of independent hard-data to obtain a plurality of bootstrap data sets from each of the plurality of subsets of independent hard-data; calculating soft-data debiased histograms for each of the obtained plurality of bootstrap data sets using a binary decision tree and the collocated soft-data; and characterizing the uncertainty of the soft-data debiased histograms.

摘要： A method for creating a facies probability cube is disclosed. A S-grid containing facies is first created. The grid includes layers of cells and columns of cells. Vertical facies proportion data for the layers of cells is derived from sources such as well data, conceptual vertical geologic sections and graphs describing the proportion of facies found in each of the layers. Areal depocenter maps are created which have defined boundaries to create depocenter regions in which respective facies are likely to occur. Ideally, the boundaries for the depocenter regions for each of the facies are sequentially and independently defined. Horizontal or map facies proportion data are generated for the columns of cells preferably by filtering the depocenter regions so that the proportion of each of the facies ranges from a maximum value to a minimum value. The vertical and horizontal facies proportion data are then integrated to create a facies probability cube in which the cells are assigned probabilities for the occurrence of facies.

摘要： A computer system and a hybrid method for combining multipoint statistic and object-based methods include creating a multi-point statistics (MPS) model using a MPS method that satisfies conditioning data and constraints in which the multi-point statistics are derived from a training image created using training-image generation parameters; generating one or more object-shape templates and depositional or structural coordinates of each facies type using the generation parameters; positioning the one or more generated templates within the MPS model such that the one or more generated templates maximally correlate to the MPS model; assigning to each of the one or more positioned templates a unique event; providing depositional or structural coordinates to each cell associated with a given event number; and modeling properties using the coordinates to capture geological trends within each template.
