ResInsight allows the user to create a ensemble RFT plot similar to summary ensemble plots. The functionality also computes statistics, e.g. P10, P90, and mean. When possible, ResInsight avoids loading the grid when reading ensemble RFT data.
When a summary ensemble has been imported, observed FMU data can be imported via right-clicking Observed Data in the Plot Project Tree, and selecting Import Observed FMU Data.
To create ensemble RFT plot, right-click RFT Plots and select New RFT Plot.
The property editor lets the user select which curves to display in the RFT plot.
Select the well to display in the plot. Wells postfixed by ’(Well Path)’ have an associated well trajectory loaded.
Subsequent to selecting a well in the Well Name field, the relevant sources for that well will appear in the Sources field. The sources for this particular case are:
When the user selects one or more sources, a selection of their time steps appears in the Time Steps field.
The Time Steps field contains the relevant time steps according to the source selection. Time steps are deemed to be relevant by the following rules:
Each time step is postfixed by letter(s) to indicate source type(s) of each time step. The source types are indicated in square brackets:
More than one letter for one single time step, means that the time step comes from multiple case types.
Visual properties of legend and axes is controlled in the same manner as for RFT plots.
Observed RFT data as part of a FMU run is presupposed to be located in a folder which contains the following four file types:
The purpose and format of the data files is explained below.
The data file well_date_rft.txt is required. If missing, no Observed FMU data will be imported.
The file layer_zone_table.txt can be used to correlate each grid k-layer with a formation name. This file is identical for all cases in the same ensemble.
Example file layer_zone_table.txt:
1 UpperReek 2 UpperReek 3 UpperReek 4 UpperReek 5 UpperReek 6 MidReek 7 MidReek 8 MidReek 9 MidReek 10 MidReek 11 LowerReek 12 LowerReek 13 LowerReek 14 LowerReek
For a given well name, the file <well_name>.obs is a data file containing two columns to specify observed pressure and error. Column one contains observed pressure and column two contains error. The observation data is valid for one and only one layer/formation.
Example file for well OP_1, i.e. OP_1.obs:
303.000 3.000 304.000 3.000 305.000 3.000
For a given well name, the file <well_name>.txt is a data file containing five columns that specify its correlation with reservoir zones. Each line of data must contain:
Example file for well OP_1, i.e. OP_1.txt:
461288.719 5933415.000 1816.200 1611.692 UpperReek 461288.685 5933415.027 1824.560 1620.052 MidReek 461288.683 5933415.029 1840.000 1635.492 LowerReek
The data file well_date_rft.txt contains well measurements. The file contains four columns for each well measurement:
There can be multiple measurement for each well.
Example file well_date_rft.txt:
OP_1 01 02 2000 1 OP_2 01 02 2000 1 OP_4 01 01 2001 1 WI_1 01 02 2000 1 WI_3 01 03 2001 1
