# Create a 3D grid (cube) using moving average as the default interpolator. # Update cube towards wells in workspace # Smooth cube with gaussian filter. # Write out inlines and crosslines in a cube to file filename. # Transform a cube or grid or polydata (points) to a new cube. |
...
Use a reference_grid in workspace to tell the layout of the result cube.
smo smoothstrength
Will use smoothing of cube at end of gridding.
Update cube towards wells in workspace.
...
Update cube towards wells in workspace checkshot_name. Moving average is the default interpolator.
check checkstart checkstop. Remove cells that has an unacceptable range within checkstart checkstop velocity.
disk - Apply disk for temporary datasets. Used to save memory and recommended for large cube gridding.
tensor - Update using b-spline tensor. [max radius]. Optionally use a max radius. [fac factor]. Optionally use a radius factor.
conic - Update using conic shape. [rad radius]. Optionally use a radius value.
two - The format of the well string is x y z two_way_travel_time. Default if not specified is x y z one_way_travel_time
cube - The format of the well string is the same as the cube: x y time cube_velocity.
Smooth cube with gaussian filter.
smo [gau dim 2] [rad radius xradius yradius zradius]
Smooth cube with gaussian filter.
gau dim 2
rad xradius yradius zradius - Apply smmothing in only 2 dimensions
z - Apply z-plane smoothing.Alternative to gaussian
rad radius - Apply a radius value in smoothing.radius factors in smoothing. The factors are given independently to x, y, and z directions. Smoothing is a weighted sum of grid nodes to the side of the centre, where the number of nodes used is 2 times the radius factor.
gau rad 0 0 zradius - Apply smoothing only in the z-direction
Write out the z values of the cube as inlines and crosslines to an external file.
write [lim limlimit_value*] _inlinestart xlinestart inlinestop xlinestop ] [xytv] [form format] inlinestart xlinestart inlinestep xlinestep filename.
Write out cube to file filename.
lim limit_value - Apply a limit and a limit_value for the number of nodes written out to test the procedure.
inlinestart xlinestart inlinestop xlinestop
xytv - The output switches inline and xline when writing x y time velocity.
formformat - Format specification of the output:
format = 1 (default) : Id inline xline x-utm y-utm time velocity
format = 2: inline xline x-utm y-utm time velocity
format = 3: xline x-utm y-utm time velocity
format = 0: x-utm y-utm time velocity
iinlinestart xlinestart inlinestep xlinestep - Specify start and stop step of inlines and crosslines to be written out.
filename - Specify file name of output.
Transform a grid or cube to a new cube.
gr3 [ins workspacename [all] ] | [fgr] | [vsum] | [edi] | [cdi] | [int] | [form]
A cube is in active data and is recalculated to a new cube.
ins workspacename [all] - Insert values from the scalar data part in workspacename (grid, cube or polydata) into a cube in active. . The all argument will insert into all neighboring cells as well.
fgr - Fill the cube in active with interpolated values for all undefined values.
vsum - Sum the cube in active vertically.
edi - Evaluate distance in 2d grid in active into a new 3d cube.
cdi - Use computed distance in 3d grid for undefined.
int - Interpolate between layers in the cube. See command object Cube generation of all layers.
form [const a b c] [min max]. Using a formula for velocity cube gridding. Makes a time velocity cube based on a regression formula. Input is the seabed grid and the constant a, b and c that is present in the formula. The twt grid in the formula is the layers in the cube. min maxis the min and max values for the new cube.
...
filt impl, gen - Generate grid
lim limit_value - Apply a limit and a limit_value for the number of nodes written out to test the procedure.
