摘要： An enlarged computer graphic image of seismic data (66) is displayed on a concave three-dimensional surface (68) having a shape corresponding to the shape of selected data extracted from a three-dimensional seismic volume (70). Thus providing an enlarged image of a seismic surface where the data is spatially correct in three-dimensions, and which increases the ease with which interpreters can locate geological features such as horizon, faults, and channels (76).

摘要： A method and apparatus for predicting distribution of reservoir permeability or porosity and pseudo relative permeability using well data (80) and 3-D seismic data (80) are disclosed, where a preferred first step (82) in the method models the reservoir property of interest to provide model logs (86) which are expressible as continuous curves of a reservoir property as a function of depth. The next step (88) selects individual data points on the continuous curves traversing a reservoir layer and determines permeable trends (96) for a multitude of column-like subvolumes which each enclose a portion of the selected data points. The subvolumes are then divided (100) into a desired number of horizontal slices, with each slice containing a number of the model data points.

摘要： A computer implemented method for mapping seismic attributes derived from analysis of isochron measurements. According to the method planar surfaces, which model the upper and lower surface of a subterranean layer (42, 44), are numerically inserted in a seismic data volume with the edges of the planar surfaces connecting reflection events of a three-by-three array of seismic traces. Using the model surfaces isochron attributes are calculated including the amount of isochron thickening (46) or thinning in the direction of dip, and the azimuth of maximum thickness change (48). The thus calculated attributes are written to data cubes, which can be displayed (50) in a variety of ways.

摘要： A desktop (28) based projector screen having an inner concave display surface (30) upon which a video image (20) or a series of images is projected (23) with a sense of realism comparable with natural viewing of a three-dimensional physical reality. The viewing surface combines three concave sections which are derived from solid figures including a dome (30), a semicylindrical wall section (22) and a semicircular floor section (25).

摘要： A computer implemented apparatus and method (Fig 3) for discovering hydrocarbon bearing formations yields a direct indication of hydrocarbon resulting from analyzing seismic amplitude data. The method uses an algorithm for determining a seismic attribute dip (DAD) (28) in which each sample point of each seismic trace in a survey is analyzed to determine a planar dip associated with the reflection point (20), and a normalized delta amplitude in the direction of dip. Displaying the DAD values in time slice or horizon slice (21) provides a direct indicator of hydrocarbons. The inventive method automatically analyzes each digitized data point in the survey by cross-correlating the traces reflected from a three-by-three array (21) of reflection points. This method involves cross-correlation of eight traces that are reflected from the perimeter of the three-by-three array of reflection points (24) with the single trace reflected from the central point in the array. The correlation is carried out over a predefined time window, and for a series of lags. A dipping plane is then trial fitted to amplitude events for the nine traces, including lagged traces, so that the cross-correlation coherency of traces in the array is optimized for a particular strike and dip position of the dipping plane. The strike and dip of the optimum plane is recorded for later use in calculating the DAD value.

摘要： A computer implemented method and apparatus is disclosed for automatically picking faults (24) in a recorded 3D seismic trace data volume (20). The method employs test planes, which are mathematically inserted into the same data volume (20) to approximate dip and azimuth of a potential fault plane surface (33). A large number of data points, which are selected points on the seismic traces, are defined within the seismic volume (20), such that each test plane positioned in the seismic volume (20) contains data points corresponding to at least a significant portion of traces. The method then determines a factor for each data point which is representative of the probability that the data point resides on a fault plane (33). This probability is based on planar discontinuity and average amplitude difference between corresponding traces in adjacent parallel test planes, and the method selects locations, in an x, y grid, of a strip of locations having high probability of residing on a fault surface (94). The strip of the selected locations is smoothed to a line and used to construct fault lineaments displays in seismic sections or time slices. The fault lineaments are stored in a computer data file (24) and conventional, stratigraphically enhanced, or other seismic data enhanced for seismic attributes is merged with the fault lineament files to create consolidated displays to aid interpretation of the data volume (33).

摘要： A method and apparatus for predicting barriers to fluid flow in a subterranean reservoir using well data (18) and 3-D seismic data (16, 18) are disclosed, where a preferred first step (82) in the method models petrophysical properties of the reservoir to provide model logs which are expressible as continuous curves of a reservoir property as a function of depth. The next step (84) selects individual data points on the continuous curves, which traverse a subterranean layer, and assigns a flow or nonflow state to each data point based on comparing a threshold value of a reservoir property with the value predicted by the data point. The layer is divided into a multitude of subvolumes each containing a single data point, and then a connectivity factor, which considers multiple flow paths around each data point, is calculated for each subvolume. The subvolumes are then grouped into larger volumes called simulation cells, and directional flow numbers are assigned to the cells relative to three mutually perpendicular x, y and z coordinate axes, such that display of the directional flow numbers for a group of cells demonstrates flow barriers and flow paths in the reservoir.
