GEOMODELING SEMANTIC WORKFLOW

GOAL

The “GEOMODELING SEMANTIC WORKFLOW”, is a project in the digital transformation domain. It intends to realize an operational prototype of atomic business activities management to activate complex operations in Geosciences in the cloud. 

The overall and long-term Geoscientific business objective of this project is to build, test and finally deploy an Open Geoscientific Workflow Platform able to associate and orchestrate / choreograph activities semantically characterized.  It would be used to cover the petroleum exploration/ production domain.

The project intends to experiment and test the replacement of monolithic application internal workflows by a combination of micro services, Web Applications, and Docker encapsulation of existing functions and algorithms available from the cloud (but not only). The monitoring of this system will be provided by a workflow orchestration / choreography platform.

The experimental and operational prototypes will be setup between geomodelling activities able to exchange information by using the Energistics standards (WITSML, RESQML, PRODML, EPC) and able to research other available information on an OSDU Platform.

In the end, the business objective of GEOSIRIS is to design and setup a technical architecture on the “future” OSDU data platform services aiming to help the whole Geomodeling community ( Petroleum Geosciences, Geological National Surveys, Geological risks and Geotechnics organisations) to compose and execute workflows based on atomic geomodeling activities deployed on the cloud and able to read and write RESQML entities and models.

A number of pre composed workflows would be presented to the users and can be combined by example to execute sensibility and uncertainty evaluation. The intention is not only to integrate GEOSIRIS atomic activities but propose the use of this platform to several other partners. The users should also, by themselves be able to combine these activities in new workflows.

RESULTS

During a first Phd by Belaid, Nabil.in 2011(Modélisation de services et de workflows sémantiques à base d’ontologies et d’indexations. Application à la modélisation géologique. Thèse de Doctorat, ENSMA Poitiers), a team headed by Yamine Aït Ameur and Jean François Rainaud were working on this subject and publish a first paper: Toward a Semantic Management of Geological Modeling Workflows. KEOD, pp. 282-287. The business needs and some of the technical solutions envisaged for this project were presented in June 2017 at a poster session by GEOSIRIS during the EAGE conference and Exhibition: Workshop 18 – Geoscience & Reservoir Integration in Studies: tools and methods.

During 2019 GEOSIRIS has already developed a Tomcat9/ html5 Client/server Web release of its Resqml Explorer/Editor (The RESQML Web Studio now) and is involved this year in the development of the OSDU R3 Release Preparation and loading and the OSDU Reservoir Domain Management System project. In parallel, GEOSIRIS is now improving the development of Web Apps and Dockers which encapsulate one by one interactive or batch activity extracted from its two “on premise” existing prototypes.

From the beginning of this year, some of these services (from micro to docker) are developed, and will be incorporated at least during the first quarter of 2021 into an operational MVP (Minimal Viable Product) workflow of “RESQML Activities on the cloud”.

Then, this will open the way to accept other services than the GEOSIRIS’s ones in an open workflow environment which could be shared by several other entities (i.e by incorporating vendor SME atomic activities).
