Agenda

Wellbore applications for fiber optic sensing has significantly expanded since their introduction into the oil field in the 1990s.  Fiber optic sensing was initially limited to wellbore temperature and pressure.  More recently, using fiber optic sensors for seismic acquisitions taking measurements fare beyond the wellbore. Continued improvement in instrument capabilities, fiber design and engineered cables are ushering in new measurement applications that include multi-component seismic, enhanced distributed temperature and magnetic sensing. This session will focus on novel and innovative subsurface applications of new and existing fiber optic sensing technologies.

With increasing use of distributed sensing (DTS/DAS) over the past decade, qualitative observations from DTS and DAS can be transformed into quantified measures such as rates and phase distribution. This session will let colleagues share and discuss leading work in quantitative interpretation solutions for measurements in both producers and injectors. 

The purpose of the digital oilfield is to maximize oilfield recovery, eliminate non-productive time, and increase profitability through the design and deployment of integrated workflows. Historically, in-well surveillance, pressure, temperature and other physical and dynamic properties have been used to monitor well performance and make informed, real-time decisions to best manage well production. The introduction of distributed data types like DTS and DAS which can be deployed permanently provide real-time data in the form of temperature, sound etc. This has significantly increased the type of information that can be obtained regarding downhole fluid behaviour and composition which in turn assists in achieving the digital oilfield goals.

This session will look at recent advancements in distributed fiber-optics sensing with a focus on the application and impact on the digital oil field. The data integration and management challenges introduced in combining real-time distributed data with existing dataset will be discussed and how workflow modifications can be incorporated to ensure improved operational efficiency and production optimisation with the aid of fiber optics data.

Distributed sensing became an important part of well interventions with the advent of fiber-optic coiled tubing telemetry. After many years of continuous use, the range of applications and means of conveyance have expanded, new workflows have emerged, and best practices been identified. This session aims to explore how the use of Distributed Temperature and Acoustic Sensing has reshaped well interventions, optimized operational workflows, and unlocked new opportunities and efficiency gains.

Seismic applications utilizing distributed acoustics sensing (DAS) have successfully demonstrated value from time-lapse offshore and onshore EOR monitoring applications. Leveraging existing permanently installed fiber optics for production monitoring, emerging temporary deployed fiber or dedicated DAS fiber, acquisition of time-lapse seismic using DAS is becoming an integral part of reservoir production management. This session will explore case studies, lessons learned as well as anticipated and/or realized value of DAS seismic applications.

This session will address the enabling technologies that can lead to practical use of fiber optic systems in existing as well as new oil and gas emerging applications. The topics include new fiber-optic and cable designs, deployment methods, downhole and subsea wet-connects, and measurement techniques that can deliver economic value and/or reduce operational risks across the oil and gas business.

In-well Fiber Optic monitoring systems are now becoming common place in offshore platform and subsea applications. This session will discuss case studies or application scenarios which illustrate the value that the different types of permanently deployed optical sensing solutions can provide in offshore applications and how some of the historical challenges of offshore deployments have been addressed through technological advances and investment resulting in the industry adopting in-well optical surveillance as a standard.

Well integrity is critical to our business. This session highlights the use of distributed fibre sensing for well integrity monitoring and new developments within this area. This includes data acquisition, integration, interpretation and how fibre optic data can contribute to the identification and remedial actions of well integrity issues.
