Abstract

Abstract A method for interactive contouring of seismic data for procuring seismic maps (60a, 60b, 60c) which provide a three-dimensional picture of the various structural layers (5a-5n, 12a-12n, respectively) within an area (11) which is circumscribed by intersecting shooting lines (6a-6d). In order to achieve a shorter processing time for procuring such maps, the data representing the individual structural layers (5a-5n) referred to a fixed reference line (2a) are procured as a color coded echo line (12h) on a graphic data screen (22), the indication of depth being given as a color value in relation to a preselected color scale (40). The interpreter can insert between the various points having the same color value on the echo line (12h) fresh interpreted values in the same grid according to the same color code, so that for each structural layer (5a-5n, 12a-12n, respectively) there can be provided a mapping (60a-60n) having surface adaptations given in various color values directly on the screen (22). The graphic display of the structural layer maps can be reproduced three-dimensionally on a color value printer (31) directly from the screen (22).

Claims Analysis

Total Claims: 20
Claim 1
Independent Claim 162 words
A method for interactive contouring of seismic data for producing a three-dimensional reproduction of various structural layers within an area defined by heading lines along which a seismic vessel is moving during seismic operations, comprising: selecting seismic data representing a plurality of individual structural layers referred to a fixed reference line; pre-selecting color values on a color scale to indicate various depths of said seismic data relative to said fixed reference line; producing each of said individual structural layers on a graphic data screen as a separate color coded echo line, the depth along each echo line being indicated by said pre-selected colors; inserting on the graphic data screen between various points on each echo line having the same color value interpreted contour lines indicating elevations to produce a mapping on said graphic data screen having surface adaptations given in various color values; and printing out on a color value printer the graphic display on said screen to produce a three-dimensional map.
Claim 2
Independent Claim 162 words
A method for interactive contouring of seismic data for producing a three-dimensional reproduction of various structural layers within an area defined by heading lines along which a seismic vessel is moving during seismic operations, comprising: selecting seismic data representing a plurality of individual structural layers referred to a fixed reference line; pre-selecting color values on a color scale to indicate various depths of said seismic data relative to said fixed reference line; producing each of said individual structural layers on a graphic data screen as a separate color coded echo line, the depth along each echo line being indicated by said pre-selected colors; inserting on the graphic data screen between various points on each echo line having the same color value interpreted contour lines indicating elevations to produce a mapping on said graphic data screen having surface adaptations given in various color values; and printing out on a color value printer the graphic display on said screen to produce a three-dimensional map.
Claim 3
Dependent Claim 45 words
A method as claimed in claim 1 and further comprising: transferring the data on said echo lines which in treated form represent said plurality of structural layers below an area circumscribed by said heading lines interactively from a data terminal device to the graphic screen.
Claim 4
Dependent Claim 24 words
A method as claimed in claim 1 and further comprising: indicating points on the graphic screen having the same color value by flashing fields.
Claim 5
Dependent Claim 24 words
A method as claimed in claim 2 and further comprising: indicating points on the graphic screen having the same color value by flashing fields.
Claim 6
Dependent Claim 32 words
A method as claimed in claim 1 and further comprising: indicating points on the graphic screen having the same color value by fields having a color different from said same color value.
Claim 7
Dependent Claim 32 words
A method as claimed in claim 2 and further comprising: indicating points on the graphic screen having the same color value by fields having a color different from said same color value.
Claim 8
Dependent Claim 37 words
A method as claimed in claim 3 and further comprising: initiating said indication of points having the same color value by a cursor when said same color value is on one of said color coded echo lines.
Claim 9
Dependent Claim 37 words
A method as claimed in claim 4 and further comprising: initiating said indication of points having the same color value by a cursor when said same color value is on one of said color coded echo lines.
Claim 10
Dependent Claim 33 words
A method as claimed in claim 4 and further comprising: initiating said indication of points having the same color value by a preselected value on a separate value scale on the graphic screen.
Claim 11
Dependent Claim 33 words
A method as claimed in claim 6 and further comprising: initiating said indication of points having the same color value by a preselected value on a separate value scale on the graphic screen.
Claim 12
Dependent Claim 21 words
A method as claimed in claim 1 and further comprising: marking discontinuous data for an echo line with a neutral color.
Claim 13
Dependent Claim 21 words
A method as claimed in claim 4 and further comprising: marking discontinuous data for an echo line with a neutral color.
Claim 14
Dependent Claim 27 words
A method as claimed in claim 1 and further comprising: marking discontinuous data for an echo line with a color value different from said preselected color value.
Claim 15
Dependent Claim 27 words
A method as claimed in claim 4 and further comprising: marking discontinuous data for an echo line with a color value different from said preselected color value.
Claim 16
Dependent Claim 33 words
A method as claimed in claim 1 and further comprising: marking said contour lines with a neutral color; and subsequently marking said contour lines with a preselected color corresponding to the contour depth.
Claim 17
Dependent Claim 33 words
A method as claimed in claim 2 and further comprising: marking said contour lines with a neutral color; and subsequently marking said contour lines with a preselected color corresponding to the contour depth.
Claim 18
Dependent Claim 33 words
A method as claimed in claim 3 and further comprising: marking said contour lines with a neutral color; and subsequently marking said contour lines with a preselected color corresponding to the contour depth.
Claim 19
Dependent Claim 33 words
A method as claimed in claim 4 and further comprising: marking said contour lines with a neutral color; and subsequently marking said contour lines with a preselected color corresponding to the contour depth.
Claim 20
Dependent Claim 33 words
A method as claimed in claim 12 and further comprising: marking said contour lines with a neutral color; and subsequently marking said contour lines with a preselected color corresponding to the contour depth.
