RI_WELLMOD

ri_wellmod is a command line utility to generate Eclipse well model definitions (WELSPECS/WELSPECL, COMPDAT/COMPDATL, WELSEGS, COMPSEGS) using ResInsight. The script takes as input a ResInsight project with wells and completions defined, in addition to an Eclipse case (either an initialized case or an input case with grid and PERMX|Y|Z and NTG defined in the GRDECL format).

Note

Well names specified as command line arguments are assumed to refer to the Eclipse well names, i.e., the completion export names as defined in the ResInsight wells project.

Examples

Example 1

To create well definitions in a file with the default name welldefs.sch:

> ri_wellmod wells.rsp DROGON-0

Here DROGON-0 is an initialized Eclipse case (i.e., the files DROGON-0.INIT and DROGON-0.EGRID/DROGON-0.GRID exist), and wells.rsp is a ResInsight project with wells and completions defined:

Example wells project — Example ResInsight project with wells for the Drogon case

Example 2

By default multi-segment well definitions are not created, but may be requested for some or all wells using a command-line argument. E.g., to add MSW data for the well A44 and any wells starting with C based on a NOSIM case:

> ri_wellmod wells.rsp DROGON-0_NOSIM --msw A4,C*

Example 3

Instead of using an initialized Eclipse case an input GRDECL case may be used. To create meaningful connection factors PERMX/PERMY/PERMZ and NTG (if non-unit) must be specified, either in the GRDECL file or in separate files, as in this exapmle:

> ri_wellmod wells.rsp ../include/grid/drogon.grid.grdecl \
  --property_files ../include/grid/drogon.perm.grdecl ../include/grid/drogon.ntg.grdecl

Example 4

ResInsight supports local grid refinement, and will automatically create WELSPECL/COMPDATL/COMPSEGL when given an initialized Eclipse case with LGR(s):

> ri_wellmod wells.rsp DROGON-0_NOSIM_LGR --msw A4 -o wells_lgr.sch

Example 5

It is also possible to create local LGRs surrounding each well, and this may be specified on the script command line. The following example adds a 3x3x2 refinement to the region of cells perforated by the well A4 and a 1x1x3 refinement around A6:

> ri_wellmod wells.rsp DROGON-0_NOSIM --lgr A4:3,3,2 A6:1,1,3 -msw A4 \
 --lgr_output_file lgr_definitions.inc

The corresponding CARFIN keywords are found in a separate file (here lgr_definitions.inc), to be included in the GRID section of the Eclipse .DATA file.
