rms.create_bw_per_facies

The RMS python job to generate new blocked wells with petrophysical values for one facies per blocked well log is used as part of a workflow to create petrophysical 3D grid realizations conditioned to only one facies. This is used in FMU workflows where both facies and petrophysical variables are used as field parameters in assisted history matching (AHM) with ERT.

Input

• Grid name

• Existing blocked well set (containing the original blocked well logs)

• List of original petrophysical blocked well log names to be used to generate new logs

• Facies log name

• Python dictionary with code and facies names per code for relevant facies

Output

For each of the specified original petrophysical logs, one new log per facies for the specified facies is made. The values are copies of the original blocked well logs except that all values belonging to other facies than the one for the created log is set to undefined. The new logs will have name of the form “faciesname_petroname”.

Example of use as RMS python job

from fmu.tools.rms import create_bw_per_facies
from fmu.config import utilities as ut
DEBUG_PRINT = False

CFG = ut.yaml_load("../../fmuconfig/output/global_variables.yml")["global"]
FACIES_ZONE = CFG["FACIES_ZONE"]

GRID_NAMES = {
     "Valysar": "Geogrid_Valysar",
     "Therys":  "Geogrid_Therys",
     "Volon":   "Geogrid_Volon",
}

# Blocked well set
BW_NAME = "BW"

# Original logs to make copy of per facies
ORIGINAL_BW_LOG_NAMES = ["PHIT", "KLOGH"]

# Facies log in original blocked well set
FACIES_LOG_NAME = "Facies"

def main(project):
     for zone_name, facies_code_names_for_zone  in FACIES_ZONE.items():
          # For each of the single zone grids, calculate updated BW set
          create_bw_per_facies(
               project,
               GRID_NAMES[zone_name],
               BW_NAME,
               ORIGINAL_BW_LOG_NAMES,
               FACIES_LOG_NAME,
               FACIES_ZONE[zone_name],
               debug_print=DEBUG_PRINT)

if __name__ == "__main__":
     main(project)

The example above will create the following new blocked well logs for each well based on the original logs “PHIT” and “KLOGH”:

• Floodplain_PHIT

• Floodplain_KLOGH

• Channel_PHIT

• Channel_KLOGH

• Crevasse_PHIT

• Crevasse_KLOGH

• Coal_PHIT

• Coal_KLOGH
