A primary request is received that includes a primary identity. The service is within a service container group project hosted by a cloud provider. A shadow request is generated from the primary request. The shadow request includes a shadow identity linked to the primary identity. The shadow request is authorized by verifying that the shadow identity has access to the service. A tenant token is generated for the shadow identity in response to authorizing the shadow request. An access token is obtained using native authorization of the cloud provider in exchange for the tenant token. Tenant data is accessed from a tenant data repository using the access token. A shadow response is obtained that is generated for the shadow identity and includes processed tenant data generated. A primary response is sent that is for the primary identity and is generated from the shadow response.

One aspect of the invention relates to a method () for characterizing a well () using distributed temperature sensor (DTS) data to optimise a well model (). The method comprises providing a well model of flow and thermal properties () of the well (), where the well model () has a plurality of adjustable physical parameters, providing a data set made up of a plurality of DTS temperature profiles of the well () taken at different times during operation of the well (), and running the well model () with different combinations of the plurality of adjustable physical parameters to match to the plurality of DTS temperature profiles. The DTS temperature profiles may also be pre-processed to make them consistent with one another.
