Installation with pip

pip install cognite-wells-sdk

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)

Well queries

Get well by asset external id or matching id

well: Well = client.wells.retrieve(asset_external_id="VOLVE:15/9-F-15")

# OR specify matching_id

well: Well = client.wells.retrieve(matching_id="kfe72ik")

Get multiple wells by asset external ids or matching ids

wells = client.wells.retrieve_multiple(
    asset_external_ids=["VOLVE:15/9-F-15"],
    matching_ids=["je93kmf"]
)

Delete well

Warning! Note that if you delete a well, it will cascade to delete all wellbores, measurements, trajectories, NPT events, and NDS events connected to that well asset.

to_delete: List[AssetSource] = [AssetSource(asset_external_id="VOLVE:15/9-F-15", source_name="VOLVE")]
client.wells.delete(to_delete)

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.

Well structured file extractor

This SDK has a work-in-progress support for the Well Structured File Extractor (WSFE). The WSFE is a service with a HTTP interface that lets you extract data from LAS, LIS, ASC, and DLIS files and creates CDF squences from them.

NB: The API is subject to change, so please make sure you are using the latest version of the SDK.

Usage

The arguments for creating a WellLogExtractorClient is the same as for CogniteWellsClient and CogniteClient. The example below authenticates using a token.

from cognite.well_model.wsfe.client import WellLogExtractorClient
from cognite.well_model.wsfe.models import CdfFileLocator, CdfSource, Destination, FileType

wsfe = WellLogExtractorClient(
    client_name="test",
    project="subsurface-test",
    cluster="greenfield",
    token="YOUR BEARER TOKEN
)

To use the extractor service, you must first upload some DLIS, LAS, ASC, or LIS files to CDF files. Then you can queue the files like this:

items = [
    CdfFileLocator(
        source=CdfSource(
            file_external_id = "dlis:889",
            file_type=FileType.dlis
        ),
        destination=Destination(datasetExternalId="volve"),
        contains_trajectory = False,
    )
]
status_map = wsfe.submit(items)

The wsfe.submit call will return a Dict[str, int] response. The string is the external id of the file and the int is a process id. To get the current status, you can run:

process_ids = [2145596483]  # or list(status_map.values())
result = wsfe.status(process_ids)
for key, process_state in result.items():
    log = process_state.log
    for seq in process_state.created_sequences:
        print("Created sequence:", seq)
    for event in log.events:
        print(f"{event.timestamp} [{event.severity.value}], {event.message}")

Output might look like this:
