    摘要: A method of transforming geologic data relating to a subsurface region between a geophysical depth domain and a geologic age domain is disclosed. A set of topologically consistent surfaces is obtained that correspond to seismic data. The surfaces are enumerated in the depth domain. An age is assigned to each surface in the depth domain. The age corresponds to an estimated time of deposition of the respective surface. An age mapping volume is generated. An extent of the age domain is chosen. A depth mapping volume is generated. Both the age mapping volume and the depth mapping volume are used to transform geophysical, geologic, or engineering data or interpretations between the depth domain and the age domain and vice versa. The geophysical, geologic, or engineering data or interpretations transformed by at least one of the age mapping volume and the depth mapping volume are outputted.

    摘要: A method, apparatus, and program product clean seismic horizon interpretation data to better represent the geological form of the data, generally through the use of a combination of one or more computer-implemented algorithms indicative of data quality to assess the likely geological validity of the data. The processed data may be used with cut-offs to selectively remove poorer quality data and retain good quality data. In addition, distances from faults may be considered when applying the computer-implemented algorithms.

    摘要: A method of determining a search expression describing a feature of interest in a set of data points distributed throughout a geological object is provided. Each data point contains a value for a geological attribute at that point. The search expression has a plurality of entries. The method including the steps of: (i) displaying the geological object using display codings corresponding to value subranges for the geological attribute such that all data points which have values for the geological attribute falling within a given value subrange are displayed with the same coding; (ii) selecting a plurality of data points of the feature of interest; and (iii) allocating value characters to entries of the search expression, the value characters corresponding to the value subranges for the geological attribute of the selected data points.

    摘要: The invention concerns a method for extracting a geological horizon and related properties of a seismic representation, comprising a step (100) which consists in digital modelling with continuous local seismic traces, calculating the optimal offset and defining a conditional neighbourhood of a reference central continuous local seismic trace; a step (101) which consists in defining a two-dimensional matrix whereof the line and column indices correspond to the coordinates of the geophones; a third step (102) which consists in selecting a seed point; a fourth step (103) which consists in determining the point vertically closest to the seed point and a fifth step (104) which consists in assigning to the point P(p,q,t) the value P(p,q,t + hij,pq,k),where hij,pq,k is the optimal offset of the neighbouring point P(i,j,k), so as to estimate the related properties of the conditional neighbourhood thereby filling the two-dimensional extraction matrix of step (101).

    摘要: Automated systems and methods that provide robust identification of regions of interest for reservoir modeling are disclosed herein. One embodiment includes: obtaining a seismic image of a subsurface region; performing full-volume horizon picking and deriving an instantaneous isochron attribute (IIA) value for each point in the seismic image; identifying one or more geobodies within the seismic image based at least in part on the IIA values; and representing the one or more geobodies in a geocellular model. The identifying of geobodies may include: applying IIA value filtering to isolate intervals of rapid or slow deposition in the seismic image; determining a reservoir-non-reservoir indicator attribute value for each point in the seismic image; applying reservoir-non-reservoir indicator value filtering to isolate subintervals of presumed reservoirs or non-reservoirs in said isolated intervals; determining a pay indicator attribute value for each point in the seismic image; and applying pay indicator value filtering to isolate presumed pay zones in said isolated subintervals.
