摘要： A model of the geological properties in a volume of the earth is created by distributing a plurality of points in the volume in the absence of a grid. Each point has a location. A first vector is assigned to a first point of the plurality of points. The first vector has a length, a magnitude, and a direction derived from a geological property in the neighborhood of the location of the first point. The magnitude of the first vector represents the value of the geological property in the neighborhood of the first point. The direction of the first vector represents the direction of maximum continuity. The direction of maximum continuity is the direction in the volume along which the magnitude of the geological property stays substantially the same for the greatest distance when moving away from the first point. The length of the first vector represents the distance through the volume from the first point in the direction of the first vector that the magnitude and direction of maximum continuity of the geological property stay substantially the same.

摘要： A model is created by distributing a plurality of points in the volume in the absence of a grid. Each point has a location. A first vector, having a length, a magnitude representing the value of the geological property in the neighborhood of the first point, and a direction representing the direction of maximum continuity, derived from a geological property in the neighborhood of the location of the first point, is assigned to a first point of the plurality of points. The direction of maximum continuity is the direction along which the magnitude of the geological property stays substantially the same for the greatest distance when moving away from the first point. The length of the first vector represents the distance from the first point in the direction of the first vector that the magnitude and direction of maximum continuity of the geological property stay substantially the same.

摘要： Calculating a fault throw. At least some embodiments are methods of determining an underground surface or horizon including: identifying an occluded zone residing between a first and second faults, the occluded zone not penetrated by an actual borehole, and the first and second faults intersect an expected location of the surface; calculating a fault throw for the first fault; and calculating the underground surface using the fault throw. Calculating the fault throw may include: calculating a first pseudo depth at a first end of the first fault, the calculating the first pseudo depth using at least one actual depth value that resides across the first fault from the first end; calculating a second pseudo depth at a second end of the first fault, the second end distinct from the first end; and determining the fault throw using the first and second pseudo depths.

摘要： Models of underground formations. At least some of the illustrative embodiments are methods including creating a model of an underground formation. The creating may include: calculating a set of probabilities associated with a first horizontal location, each probability indicative of a likelihood of finding abutting geological layers; estimating a plurality of successions of geological layers to create a plurality of estimated successions, and the estimating using the set of probabilities; determining, for each of the estimated succession, a value indicative of how closely each estimated succession matches a measured succession, the measured succession determined by a seismic survey; and selecting from the plurality of estimated successions based on the values, the selecting creates a selected succession of geological layers, and the plurality of modeled values associated with the first horizontal location determined based on the selected succession of geological layers.
