Training Course: Design of Fiber-Optic DTS and DAS Well Installations
Ticketed Event
Instructor(s) Bill Shroyer; Dr. Dennis Dria

This one-day training event introduces completion, production, surveillance and reservoir engineers to the design of fiber-optic DTS (distributed temperature sensing) and DAS (distributed acoustic sensing) well installations.  A basic understanding of the principles and benefits of DTS, DAS and surveillance monitoring technology in general is assumed.

Upon completion of this course, participants will have an understanding of:

Technical and economic factors that influence the selection and justification for installing DAS/DTS systems in specific well types.

Completion and monitoring components needed to deliver a DAS/DTS-monitored well.

Installation and commissioning operations.

The first segment of the training covers the background and procedures for selecting candidate wells for DAS and DTS monitoring and for selecting specific monitoring options such as DTS, DAS and pressure gauges. A brief set of examples and exercises will illustrate the cost-benefit analysis one may employ during the selection and planning phases.

The second training segment addresses the completion components, installation equipment and processes, and the commissioning and start-up procedures needed to install and operate a fiber-optic monitoring system. Several well configurations will be considered, including offshore (dry tree), onshore oil and unconventional gas, thermal, and injection wells.

Session 3: Integrity, Flow Assurance, and Pipeline Monitoring
Session Chairpersons Jyotsna Sharma, Louisiana State University; Doug Norton, AFL; Pierre Ramondenc, SLB

Incidents involving pipelines have raised awareness of the need for better methods to prevent and mitigate potential problems related to the transportation of hydrocarbons.  With the current focus placed on CCUS, the industry also needs to evaluate robust surveillance technologies and strategies to ensure the integrity of installations and proper sequestration.  The adoption of distributed fiber optic sensing technologies to monitor wellbores, pipelines, flowlines, and facilities can provide solutions and improve public perceptions.  This session explores case histories, lessons learned, and the solutions to asset integrity and flow assurance issues in the upstream and midstream markets.  These issues include the impact of installation practice on performance, event detection challenges and tradeoffs, and new features and capabilities.

Session 4: Lower Carbon Applications (CCUS and Geothermal)
Session Chairpersons Richard Temple, Chevron; Pierre-Francois Roux, Baker Hughes

The energy transition involves many different technologies – from Geological Carbon Storage to geothermal and renewable energies. Common to all these technologies is the need to provide monitoring solutions, in order to ensure safe and efficient operations. Distributed sensing has already proven extremely valuable for CCS with numerous examples of 4D VSP acquired with fiber in projects worldwide (CO2CRC in Otway, Australia, SECARB in Citronelle, AL, USA, Aquistore, Canada), as well as (micro) seismic monitoring for geothermal (Forge). Other applications, such as strain and temperature monitoring, are also very promising. This session will cover case histories in the broad context of energy transition, and will seek to demonstrate how distributed sensing can support the energy transition.
