Installation with pip

Usage

Authenticating and creating a client

With environment variables

NOTE: must be valid for both cdf and geospatial API

export COGNITE_PROJECT=<project-tenant>
export COGNITE_API_KEY=<your-api-key>

You can then initialize the client with

from cognite.well_model import CogniteWellsClient
wells_client = CogniteWellsClient()

Without environment variables

Alternatively, the client can be initialized like this:

import os
from cognite.well_model import CogniteWellsClient
api_key = os.environ["COGNITE_API_KEY"]
wells_client = CogniteWellsClient(project="your-project", api_key=api_key)

Connect to a different CDF environment

from cognite.well_model import CogniteWellsClient, Cluster
wells_client = CogniteWellsClient(cluster = Cluster.BP)

Well queries

Get well by id

well = wells_client.wells.get_by_id(8456650753594878)

List wells

wells = wells_client.wells.list()

Filter wells by wkt polygon

from cognite.well_model.models import PolygonFilter

polygon = 'POLYGON ((0.0 0.0, 0.0 80.0, 80.0 80.0, 80.0 0.0, 0.0 0.0))'
wells = wells_client.wells.filter(polygon=PolygonFilter(geometry=polygon, crs="epsg:4326"))

Filter wells by wkt polygon, name/description and specify desired outputCrs

polygon = 'POLYGON ((0.0 0.0, 0.0 80.0, 80.0 80.0, 80.0 0.0, 0.0 0.0))'
wells = wells_client.wells.filter(
    polygon=PolygonFilter(geometry=polygon, crs="epsg:4326", geometry_type="WKT"),
    string_matching="16/",
    output_crs="EPSG:23031"
)

Get wells that have a trajectory

from cognite.well_model.models import TrajectoryFilter

wells = wells_client.wells.filter(has_trajectory=TrajectoryFilter(), limit=None)

Get wells that have a trajectory with data between certain depths

wells = wells_client.wells.filter(has_trajectory=TrajectoryFilter(min_depth=1400.0, max_depth=1500.0), limit=None)

Get wells that has the right set of measurement types

from cognite.well_model.models import MeasurementFilter, MeasurementFilters, MeasurementType

gammarayFilter = MeasurementFilter(measurement_type=MeasurementType.gamma_ray)
densityFilter = MeasurementFilter(measurement_type=MeasurementType.density)

# Get wells with all measurements
measurements_filter = MeasurementFilters(contains_all=[gammarayFilter, densityFilter])
wells = wells_client.wells.filter(has_measurements=measurements_filter, limit=None)

# Or get wells with any of the measurements
measurements_filter = MeasurementFilters(contains_any=[gammarayFilter, densityFilter])
wells = wells_client.wells.filter(has_measurements=measurements_filter, limit=None)

Get wellbores for a well id

wellbores = wells_client.wellbores.get_from_well(well.id)

or

well = wells_client.wells.get_by_id(519497487848)
wellbores = well.wellbores()

Get wellbores from multiple well ids

wellbores = wells_client.wellbores.get_from_wells([17257290836510, 8990585729991697])

Filter - list all labels

blocks = wells_client.wells.blocks()
fields = wells_client.wells.fields()
operators = wells_client.wells.operators()
quadrants = wells_client.wells.quadrants()
sources = wells_client.wells.sources()
measurementTypes = wells_client.wells.measurements()

Wellbore queries

Get wellbore by id

wellbore = wells_client.wellbores.get_by_id(2360682364100853)

Get wellbore measurement for measurementType: 'GammaRay'

measurements = wells_client.wellbores.get_measurement(wellbore_id=2360682364100853, measurement_type=MeasurementType.gamma_ray)

Get trajectory for a wellbore

wellbore = wells_client.wellbores.get_by_id(2360682364100853)
trajectory = wellbore.trajectory()

Or get it directly from a wellbore id

trajectory = wells_client.surveys.get_trajectory(2360682364100853)

Survey queries

Get data from a survey, from start and end rows

trajectory_data = wells_client.surveys.get_data(17257290836510, start=0, end=100000, columns=["MD", "AZIMUTH"])

Get all data from a survey object

trajectory = wells_client.surveys.get_trajectory(2360682364100853)
trajectory_data = trajectory.data()

Ingestion

Initialise tenant

Before ingesting any wells, the tenant must be initialized to add in the standard assets and labels used in the WDL.

from cognite.well_model import CogniteWellsClient

wells_client = CogniteWellsClient()
log_output = wells_client.ingestion.ingestion_init()
print(log_output)  # If something is wrong with authorization, you should see that in the logs

Add source

Before ingestion from a source can take place, the source must be registered in WDL.

import os
from cognite.well_model import CogniteWellsClient

wells_client = CogniteWellsClient()
created_sources = wells_client.sources.ingest_sources(["Source1, Source2"])
