In this paper recent field trials are discussed to demonstrate the value of these novel in-well fiber optic applications. These trials highlight the benefit of integrated data interpretation and the versatility of applications that are possible using fiber optic installations in wells. The applications shown are the use of the DSS for inflow profiling in a water injector in a deepwater asset, gas flow monitoring by combined interpretation of DAS and DTS data, and the first offshore applications of DAS for borehole seismic in Shell.

This paper discusses examples of using DAS for production allocation and reservoir surveillance.

This paper shows results from various field trials that demonstrate the usability of DAS for typical VSP applications such as checkshots, imaging and time-lapse monitoring.

This paper discusses how Distributed Acoustic Sensing (DAS) may be used to clear the cost affordability hurdle of time-lapse 3D VSP both onshore and offshore.

This paper demonstrates how Distributed Acoustic Sensing (DAS), a rapidly evolving fiber-optic based technology for permanent in-well and geophysical monitoring, has been used to record VSP data in multiple assets onshore Canada, USA, Europe, and the Middle East.

This paper discusses the first exploration-and-production downhole field trial of distributed acoustic sensing (DAS) fiber-optic technology, conducted during the completion of a tight gas well in February 2009.

This paper presents different horizontal well case studies that illustrate how the combination of DTS and DAS has the potential to enhance the monitoring, assessment, and optimization of openhole and limited entry designed hydraulic fracture stimulation treatments.

This paper discusses the results of a field trial of DAS VSP measurements in the Quest Carbon Capture and Storage (CCS) project in Alberta, Canada.

This paper presents results from the use of fiber-optic DAS to record VSP data in two field trials in onshore Canada and USA.

This paper presents different case studies that illustrate how DAS has the potential to enhance the capability of monitoring and understanding in-wellbore activities. The technology enables the optimization of hydraulic-fracturing design and execution, which can drive down completion costs and lead to increased well productivity and ultimate recovery.
