Extract the curve of Fluid Invaded Cells along Time

Description

Extract the curve of Fluid Invaded Cells along Time

Usage

fluid.extract(db, facies = 1, fluid = 2, date = 3, poro = 0,
              nfacies = 2, nfluids = 2, facies0 = 1, fluid0 = 1, time0 = 0,
              dtime = 1, ntime = 1, verbose = 0)

Arguments

db

The db-class structure containing the 3-D Grid file It must contain a Facies, a Fluid and a Date variables.

facies

Rank of the attribute containing the facies information. The valid facies must be numbered 1, 2, ... up to 'nfacies'. 0 should be assigned to a facies which does not receive any fluid (Shale)

fluid

Rank of the attribute containing the initial fluid information. Fluids should be numbered 1, 2, ... 'nfluids'.0 should be assigned to the cells where the fluid is not informed. The fluids should be ordered by increasing wieghts.

date

Rank of the attribute containing the date of the invasion by a fluid. Dates should start at 1.

poro

Rank of the attribute containing the Porosity information. A Porosity value is used as an REAL coefficient which multiplies the volume of a cell invaded by a fluid. Warning: a porosity must lie between 0 and 1. A value outside this interval will be brought back to the interval bounds. If this rank is set to 0, a constant porosity equal to 1 is defaulted.

nfacies

Total number of facies (starting from 1 and 0 excluded)

nfluids

Total number of fluids (starting from 1 and 0 excluded)

facies0

Rank of the target Facies (starting from 1)

fluid0

Rank of the target Fluid (starting from 1)

time0

Origin of the first Time Interval.

dtime

Width of each Time Interval.

ntime

Number of contiguous Time Intervals.

verbose

Verbose flag.

Value

The procedure generates a data frame with 4 columns and as many rows as there are time intervals. The contents of each column is as follows:
