Over the last few years there has been significant DAS data quality improvements for seismic applications through advances in both fiber and interrogator technologies, as well as new processing techniques. This session will explore advancements in fiber technologies - hardware to processing, fit-for-purpose cable designs focusing on novel applications supporting the energy industry.

Incidents involving pipelines have raised awareness of the need for better methods to prevent and mitigate potential problems related to the transportation of hydrocarbons. Meanwhile, the current efforts to reduce the environmental impact of O&G operations, to accelerate underground carbon sequestration, and to produce cleaner energy sources (such as geothermal) require robust well integrity surveillance technologies and programs. 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.

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.

This session aims to showcase new optical sensing technologies and methodologies, whether specifically designed for E&P or coming from other industries. Whether emerging or enabling, a special focus will be placed on demonstrating how the implementation of those technologies can bring significant value to fiber-optic deployment and its use, and how they can unlock new applications for reservoir surveillance, operations evaluation, and well interventions. The session will also illustrate how integration of various types of measurements can be leveraged to improve the economics and lower the risks of O&G operations.

This session will present examples of stimulation monitoring using distributed sensing methods utilizing fiber optic sensing. These diagnostics are critical for evaluating completion effectiveness and cross well interactions on well pads with multiple treatment intervals and multiple wells. Inflow distributions are also presented to illustrate relative flow contributions from each interval, and within intervals, and the dynamic flow behavior with time.  This session will also focus on decision making that leads to optimized completions/asset development.
