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.

Drawing from a panel of fiber-optic service providers, this session will be a moderated forum shedding light on the challenges to broader use of this technology within our industry. This panel of experts will identify real and perceived gaps and roadblocks to wider application of fiber optic sensing and discuss how to address these issues with the broader audience.
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 hardware and processing advancements to seismic applications, particularly through the use of novel interrogator configurations, engineered sensing fiber and fit-for-purpose cable designs.

Fiber-optic sensing provides us huge amount of data to gain insights into oil & gas exploration and production. To achieve this goal, it needs to have proper strategy and workflow to ensure desired data is collected at the right time and under the right settings, guarantee data quality during acquisition, transferring, storing and processing, as well as timely conversion of the raw data into information and a format that the decision-maker can readily use. This session will show examples of strategies and decision-making workflows that are utilized to align design with business, as well as the innovations in interoperability between various suppliers, use of standards, data management, data visualization, and data analytics.

This session will present examples of stimulation monitoring using distributed sensing methods utilizing fiber-optics sensing. These diagnostics are critical for evaluating completion effectiveness in wells with multiple treatment intervals to determine volume distribution along a wellbore. 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.
