Seismic CoKriging

Description

Seismic CoKriging

Usage

seismic.estim(db, model=model.input(), nbench = 0, nv2max = 1, 
flag.ks = FALSE, flag.std = TRUE, flag.sort=TRUE, 
flag.stat=FALSE, radix = "CoKriging", modify.target = db.locmod())

Arguments

db

Grid containing the seismic information:

  • 1 : main variable (defined in few traces)

  • 2 : secondary variable (defined almost in all traces)

model

The model-class structure containing the Model information

nbench

The number of bench corresponds to the radius of the vertical neighborhood (center excluded) where neighborhood information must be selected.

nv2max

Maximum number of traces where the second variable is defined to be used in the neighborhood

flag.ks

When TRUE, the ordinary CoKriging is used; otherwise the Simple CoKriging is performed

flag.std

When TRUE, the standard deviation of the CoKriging Estimation error is also stored

flag.sort

When TRUE, the traces are processed by incresing distance to the traces where the first variable is defined

flag.stat

When TRUE< the final statistics are printed giving:

  • - the total number of grid nodes

  • - the number of grid processed (excluding the masked ones)

  • - the number of Kriging system established

radix

Radix of the name given to the variables storing the results in the target Db.

modify.target

Decides whether or not the newly created variables will have their locator defined or not. For more information, see db.locmod.

Value

The Grid Db containing the two interpolated variables and (upon request) the two variables corresponding to the standard deviation of the estimation errors.
