| Main components: | ||
| ERT config file: sim_field.ert | ||
|
|
||
| The ERT model depends on: | ||
| scripts/sim_fields.py | ||
| scripts/common_functions.py | ||
|
|
||
| Example of optional input config scripts to | ||
| scripts/init_test_case.py and scripts/sim_fields.py: | ||
| example_case.yml | ||
| modify_variogram.yml | ||
|
|
||
| ERT keyword input: | ||
| GRID: Input grid is made by scripts/init_test_case.py | ||
| OBS_CONFIG: Observations are extracted from an upscaled realization made by scripts/init_test_case.py | ||
| GEN_DATA : Prediction of observables made by forward model SIM_FIELD which runs scripts/sim_fields.py | ||
| FIELD: Prior realizations of field made by forward model SIM_FIELD which runs scripts/sim_fields.py | ||
|
|
||
| Other ERT input files: | ||
| time_map.txt | ||
| localisation.wf | ||
|
|
||
| Other files: | ||
| randomseeds.txt - Not used by ERT, but by sim_fields.py | ||
| This file can be generated by scripts/init_test_case.py | ||
| UpscaledGrid.EGRID - Not used by ERT, but by scripts/sim_fields.py | ||
| This file can be generated by scripts/init_test_case.py | ||
|
|
||
| Typical workflow: | ||
| 1. Prepare ERT config input by running scripts/init_test_case.py. If run without any arguments, a set of hardcoded | ||
| default settings are used. Optionally add one argument (a yml file where the settings for the test case can be modified. | ||
| See example of two such yml files: example_case.yml containing all available settings and modify_variogram.yml | ||
| where only a few parameters are modified and the rest of the settings are using default values. | ||
| Edit the input yml file to change settings. | ||
| 2. Directories for observations are created automatically according to the default (or modified) settings. | ||
| 3. Make the directory init_files if not existing. | ||
| 4. Run the script init_test_case.py located under scripts from the example_case dirctory. | ||
| Run it with or without one argument which is a specification of settings. | ||
| Default settings are used for settings not specified. The file can be ommited if one want to use the default | ||
| settings for all parameters. Example file containing all possible settings is the file example_case.yml | ||
| 5. If non-default settings are specified and the init_test_case.py is run with an yml file as argument, also the ERT forward | ||
| model SIM_FIELD need the same input as the third argument for the script sim_fields.py | ||
| The first two arguments are iteration and realisation number. Edit FM_SIM_FIELD and specify wanted settings file (yml file). | ||
| 5. Activate/not activate localisation in ERT config file (HOOK_WORKFLOW LOAD_WORKFLOW for localisation) | ||
| 6. Now ready to run ERT. | ||
|
|
||
|
|
||
|
|
||
| What the script sim_fields.py do: | ||
| 1. Get iteration and realisation number from ERT using ERT environment variables _ERT_ITERATION_NUMBER and _ERT_REALIZATION_NUMBER | ||
| If running with old komodo version, the script will require iteration and realisation_number as command line input and optionally the yml settings file. | ||
| 2. If iteration = 0 then | ||
| simulate field and export to file to be used in FIELD keyword in ERT config file. | ||
| upscale field and optionally export to file for QC purpose | ||
| else | ||
| import updated field from ERT | ||
| upscale field and optionally export file for QC purpose | ||
| 3. Extract predicted values of observables from upscaled field (values for some selected grid cells related to the upscaled grid) and write GEN_DATA files | ||
| 4. Optionally write some files for QC purpose. | ||

| | ||
| ### Main Components: | ||
| | ||
| - **ERT config file:** `sim_field.ert` | ||
| | ||
| The ERT model depends on: | ||
| - `scripts/sim_fields.py` | ||
| - `scripts/common_functions.py` | ||
| | ||
| | ||
| - **ERT Keyword Input:** | ||
| - **GRID:** Input grid is made by `scripts/init_test_case.py` | ||
| - **OBS_CONFIG:** Observations are extracted from an upscaled realization made by `scripts/init_test_case.py` | ||
| - **GEN_DATA:** Prediction of observables made by forward model `SIM_FIELD` which runs `scripts/sim_fields.py` | ||
| - **FIELD:** Prior realizations of field made by forward model `SIM_FIELD` which runs `scripts/sim_fields.py` | ||
| | ||
| - **Other ERT Input Files:** | ||
| - `time_map.txt` | ||
| - `localisation.wf` | ||
| | ||
| - **Other Files:** | ||
| - `randomseeds.txt`: Not used by ERT, but by `sim_fields.py`. This file can be generated by `scripts/init_test_case.py` | ||
| - `UpscaledGrid.EGRID`: Not used by ERT, but by `sim_fields.py`. This file can be generated by `scripts/init_test_case.py` | ||
| | ||
| ### Typical Workflow: | ||
| | ||
| 1. **Preparation:** Prepare ERT config input by running `scripts/init_test_case.py`. | ||
| 2. Directories for observations are created automatically according to the default settings. | ||
| 3. Make the directory `init_files` if not existing. | ||
| 4. Activate or deactivate localisation in ERT config file (`HOOK_WORKFLOW LOAD_WORKFLOW` for localisation). | ||
| 5. Now ready to run ERT. | ||
| | ||
| ### What the Script `sim_fields.py` Does: | ||
| | ||
| 1. Get iteration and realisation number from ERT using ERT environment variables `_ERT_ITERATION_NUMBER` and `_ERT_REALIZATION_NUMBER`. If running with an old Komodo version, the script will require iteration and realisation_number as command line input. | ||
| 2. If iteration = 0, then: | ||
| - Simulate field and export to file to be used in `FIELD` keyword in ERT config file. | ||
| - Upscale field and optionally export to file for QC purpose. | ||
| Else: | ||
| - Import updated field from ERT. | ||
| - Upscale field and optionally export file for QC purpose. | ||
| 3. Extract predicted values of observables from upscaled field (values for selected grid cells related to the upscaled grid) and write `GEN_DATA` files. | ||
| 4. Optionally write some files for QC purpose.Directory for test case for non-adaptive localisation (LOCALISATION_JOB) |
