Abstract: A method of editing a surface representing a quantitative field is disclosed which facilitates getting a surface to conform to a required shape. In embodiments, the methods revise a surface display substantially in real time by altering a predetermined visual characteristic of the displayed surface as a function of changed original values, the predetermined visual characteristic comprising at least one of a contour line representative of a set of the changed original values or a one-to-one color mapping between a changed original value and color.

Abstract: A method of managing a repeated surface comprising seismic data as one surface is disclosed where a plurality of horizons is analyzed and a determination made as to which of the plurality of horizons comprise a repeated surface. Those horizons which comprise the repeated surface may then be logically connected into a logically connected horizons data set which may then be assigned a common identifier and which may further respond similarly to a single event, e.g. a user action. It is emphasized that this abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.

Abstract: The method of the present invention relates to the field of seismic data interpretation for the purpose of locating a surface in a three dimensional volume of seismic data. The present invention applies mathematical gridding to the location of surfaces in a volume.

Abstract: The method of the present invention relates to the field of seismic data interpretation for the purpose of finding natural occurrences of oil and/or gas in a geophysical formation. The invention relates to a method of processing seismic geophysical data to produce time structure volumes. The method of the present invention is capable of displaying the position and orientation of layered rocks in the subsurface of the earth.

Abstract: A method for enhancing zero-phase seismic data traces so that subtle geologic features are easier to identify and interpret. In a first embodiment, the method comprises enhancing the amplitudes of at least the peaks and troughs in the zero-phase seismic data traces. This enhancement can be accomplished in a variety of ways. In a second embodiment, the negative second difference is calculated at each sample point along the zero-phase seismic data trace to enhance bends or kinks in the data, as well as peaks and troughs.
