12:30 - 13:30
Session 1: Well Integrity
Session Chairpersons Richard Tøndel, Equinor; Mike Webster, SolaSense
Speaker(s) Håkon Sunde Bakka, Equinor; Sebastian Kroczka, Halliburton

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.

13:30 - 14:30
Session 2: Injection & Production Monitoring
Session Chairpersons Jeff App, Chevron; Evert Moes, Shell
Speaker(s) Veronique Mahue, Silixa; Mohammed Hashmi, PDO

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.

Session 3: FO in the Digital Oilfield
Session Chairpersons Steven Mathias; Iko Oguche, Tendeka
Speaker(s) Andy Nelson, Tendeka; Amar Patel, Baker Hughes, Dmitry Kortukov, Schlumberger

The purpose of the digital oilfield is to maximise 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.

Session Chairpersons Sam Gorgi, Halliburton; Pierre Ramondenc, Schlumberger
Speaker(s) Sebastian Kroczka, Halliburton; Lilia Noble, Lytt; Alessandro Delfino and Cagri Cerrahoglu, Lytt

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, optimised operational workflows, and unlocked new opportunities and efficiency gains.

Seismic applications utilising 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 realised value of DAS seismic applications.
