Forward model jobs¶

Some of the forward models are connected and often the output of one is the input to another. However, they maintain the same format, and thus a subset of the jobs can be run independently. For example, if well_constraints is not necessary, it can be omitted, and if well_order is not a concern, the input to the well_constraints can be setup and copied (in the everest configuration, rather than using the drill_planner every time). Some of them are however mandatory, e.g. the add_templates is a prerequisite for the schmerge job.

Example

forward_model:
  - fm_drill_planner -i well.json
                     -c drill_planner_config.yaml
                     -opt optimizer_values.yml
                     -o wells_dp_result.json
  - fm_well_constraints -i wells_dp_result.json
                        -c well_constraint_config.yml
                        -rc rate_input.json
                        -pc phase_input.json
                        -dc duration_input.json
                        -o wells_wc_result.json
  - fm_add_templates -c template_config.yml
                     -i wells_wc_result.json
                     -o wells_tmpl_result.json
  - fm_schmerge  -s raw_schedule.sch
                 -i wells_tmpl_result.json
                 -o result_schedule.sch

Named Arguments¶

--lint

Optional argument to activate verification of validity of all given input (file) arguments without actually executing the forward model (i.e., no data transformation, no output calculation).

Default: False

required named arguments¶

-c, --config: STEA (yaml) config file

Argument examples¶

-config example

# The id of the project, which must already exist and be available in
# the stea database. In the Stea documentation this is called "AlternativeId".
project-id: 4782
project-version: 1


# All information in stea is versioned with a timestamp. When we request a
# calculation we must specify wich date we wish to use to fetch configuration
# information for assumptions like e.g. the oil price.
config-date: 2018-07-01 12:00:00


# The stea web client works by *adjusting* the profiles in an existing
# stea project which has already been defined. That implies that all
# profiles added in this configuration file should already be part of
# the project. To match the profiles specified here with the profiles in
# the project we must give a id for the profiles.

# The profiles keyword is used to enter profile data explicitly in the
# configuration file. Each profile is identified with an id from the
# existing stea project, a start date and the actual data.

profiles:
    <ecl_profile_id>:
       start-year: 2018
       data: [100, 200, 300]

# Profiles which are calculated directly from an eclipse simulation are
# listed with the ecl-profiles key. Each profile is identified with an id
# from the stea project and an eclipe key like 'FOPT'. By default the stea
# client will calculate a profile from the full time range of the simulated
# data, but you can optionally use the keywords start-year and end-year to
# limit the time range.
ecl-profiles:
  <ecl_profile_id>:
     ecl-key: FOPT

  <ecl_profile_id>:
     ecl-key: FGPT
     start-year: 2020

Drill planner¶

A module that given a well priority list and a set of constraints, creates a list of dates for each well to be completed. Any well may have multiple options as to where it can be drilled, both for different slots and rigs. The module will try to find the optimum event combinations that allows for the wells to be completed as quickly as possible, and at the same time make sure that the dates that are output will be a valid drill plan.

Well constraints¶

A module that given a list of boundaries and well constraints creates a list of well events. Varying phase, rate and time of each event is supported. Rate and duration can be provided as constant values if the optimizer does not provide them, and phase as a list of possibilities to choose from.

usage: fm_well_constraints [-h] -i INPUT [--schema] [--lint] -o OUTPUT -c
                           CONFIG [-rc RATE_CONSTRAINTS]
                           [-pc PHASE_CONSTRAINTS] [-dc DURATION_CONSTRAINTS]

Named Arguments¶

--schema

Optional argument to generate schemas of the configuration file with its expected structure to facilitate its setting up by the user.

--lint

Optional argument to activate verification of validity of all given input (file) arguments without actually executing the forward model (i.e., no data transformation, no output calculation).

Default: False

-rc, --rate-constraints

Rate constraints file in json format, from controls section of Everest config, must be indexed format.

-pc, --phase-constraints

Phase constraints file in json format, from controls section of Everest config, must be indexed format. Values must be in the interval [0,1], i.e in a two phase case [“water”, “gas”], any control value in the interval [0, 0.5] will be attributed to “water” and any control value in the interval (0.5, 1] will be attributed to “gas”.

-dc, --duration-constraints

Duration constraints file in json format, from controls section of Everest config, must be indexed format.

required named arguments¶

-i, --input: File in json format containing well names and well opening times, should be specified in Everest config (wells.json).
-o, --output: Name of the output file. The format will be yaml.
-c, --config: Configuration file in yaml format with names, events and values

Argument examples¶

If there is an entry in e.g. the rate-constraint file for INJECT1, 1, then no rate value needs to be provided in the configuration file under index 1 for INJECT1. The optimizer values from the rate-constraint and duration-constraint files will overwrite any value provided in the configuration file for the same well and index. If the optimizer provides no rate or duration input files then any values in the configuration files will be considered as constants.

Well trajectory¶

Design a well trajectory based on provided parametrized guide points.The guide points are interpolated in order to obtain a smooth well trajectory.Then, inputs for the reservoir simulator are created in form of completion data consisting of grid cells that trajectory interjects, well-to-cell connection factors, well diameter, skin, etc. Optionally, only perforated intervals are created for which provided perforation criteria are satisfied based on information, such as geological formation or any static or dynamic property in the grid cell of a reservoir simulation model.

usage: fm_well_trajectory [-h] -c CONFIG [-E ECLIPSE_MODEL] [--lint]
                          [--schema]

Named Arguments¶

-E, --eclipse-model

Path to simulation model: ‘/path/to/model’; extension not required. GRID and INIT files always expected. If dynamic perforations defined in CONFIG file then UNRST file expected.

--lint

Optional argument to activate verification of validity of all given input (file) arguments without actually executing the forward model (i.e., no data transformation, no output calculation).

Default: False

--schema

Optional argument to generate schemas of the configuration file with its expected structure to facilitate its setting up by the user.

Eclipse simulator¶

eclipse100 <eclbase> --version <version_number>

Running eclipse with parallel option¶

It is possible to run eclipse with multiple CPUs on clusters. This requires the eclipse data file to have the parallel option and the everest config needs to specify the number of CPUs per node:

simulator:
  cores_per_realization: x

where x is an int giving the number of cores. The eclipse100 forward model also needs to be given the argument to use multiple cores:

eclipse100 <eclbase> --version <version_number> --num-cpu x

where x is the number of cores.

Everest usage example¶

The following illustrates an example of a forward model section of an Everest config file:

forward_model:
  - well_constraints  -i files/well_readydate.json -c files/wc_config.yml -rc well_rate.json -o wc_wells.json
  - add_templates     -i wc_wells.json -c files/at_config.yml -o at_wells.json
  - schmerge          -s eclipse/include/schedule/schedule.tmpl -i at_wells.json -o eclipse/include/schedule/schedule.sch
  - eclipse100        r{{ eclbase }} --version 2020.2
  - rf                -s r{{ eclbase }} -o rf

The add_templates job does NOT need to be installed it is already part of the default everest jobs. In the example above all files present in the files folder need to be provided by the user. The files folder should have the following structure:

files/
   |- well_readydate.json
   |- wc_config.yml
   |- at_config.yml
   |- templates/
       |- wconinje.j2.html
       |- wconprod.j2.html

and should be installed in the everest config file:

install_data:
  -
    source: r{{ configpath }}/../input/files
    target: files
    link: true

In the above example of the forward model section of the config file:

The file wc_wells.json is a direct output of the well_constraint job.
The add_templates job uses the same file wc_wells.json as an input for the job.
The wc_wells.json file is not modified by the user. Any modification to this file should be done using a custom job (see the section Custom forward model jobs for more information on how to do that).

If the file is to be modified by a custom job, the everest config should contain:

install_jobs:
  -
    name: custom_job
    executable: jobs/custom_job.exe

forward_model:
  - well_constraints  -i files/well_readydate.json -c files/wc_config.yml -rc well_rate.json -o wc_wells.json
  - custom_job        -i wc_wells.json -o wc_wells_custom.json
  - add_templates     -i wc_wells_custom.json -c files/at_config.yml -o at_wells.json
  - schmerge          -s eclipse/include/schedule/schedule.tmpl -i at_wells.json -o eclipse/include/schedule/schedule.sch
  - eclipse100        r{{ eclbase }} --version 2020.2

        "date": "2000-01-01",
        "opname": "rate"
      }
    ]
  }
]

The add_templates job will search in the file wc_wells.json for the keys defined by the user in the config file at_config.yml and where the keys are present the job will add the corresponding template file. The resulting output at_wells.json has the following form:

at_wells.json

[
  {
    "name": "PROD1",
    "readydate": "2000-01-01",
    "ops": [
      {
        "phase": "OIL",
        "rate": 550.0015,
        "date": "2000-01-01",
        "opname": "rate",
        "template": "./files/templates/wconprod.j2.html"
      }
    ]
  },
  {
    "name": "PROD2",
    "readydate": "2000-01-01",
    "ops": [
      {
        "phase": "OIL",
        "rate": 860.0048,

        "opname": "rate",
        "template": "./files/templates/wconprod.j2.html"
      }
    ]
  },
  {
    "name": "INJECT1",
    "readydate": "2000-01-01",
    "ops": [
      {
        "phase": "WATER",
        "rate": 5499.93,
        "date": "2000-01-01",
        "opname": "rate",
        "template": "./files/templates/wconinje.j2.html"
      }
    ]
  },
  {
    "name": "INJECT2",
    "readydate": "2000-01-01",
    "ops": [
      {

        "opname": "rate",
        "template": "./files/templates/wconinje.j2.html"
      }
    ]
  }
]

Next, the at_wells.json file is used as an input for the schedule merge job schmerge together with the initial schedule template schedule.tmpl file, which will result in the new schedule file schedule.sch used for the simulation.

For the following entry in the at_wells.json:

{
  "name": "PROD1",
  "readydate": "2000-01-01",
  "ops": [
    {
      "phase": "OIL",
      "rate": 550.0015,
      "date": "2000-01-01",
      "opname": "rate",
      "template": "./files/templates/wconprod.j2.html"
    }
  ]
}

and the template wconprod.j2.html:

WCONPROD
  '{{ name }}'  'OPEN'  'ORAT' {{ rate }}   4* 100   /
/

the resulting entry in schedule.sch is as follows:

--start ./files/templates/wconprod.j2.html
WCONPROD
  'PROD1'  'OPEN'  'ORAT' 550.0015   4* 100   /

--end ./files/templates/wconprod.j2.html

where "--" marks the beginning of a comment line and will be ignored by the simulator.
