In-well measurements of pressures and temperatures at discrete locations have been long used in the monitoring of reservoir and well performance. Recent advances in technologies have given us efficient and cost-effective tools to measure the pressure, temperature, strain, seismic and flow along the entire wellbore for detailed analysis of dynamic reservoir behaviour. New methods using fibre optics have gained significant foothold but aren’t yet mainstream. The multitude of high-resolution measurements that can be non-intrusively acquired in a borehole using fibre optics allows for better understanding of the dynamic reservoir behaviour. Combining the detailed near-field measurements in a well with far-field sensing methods such as 4D seismic and even 4D electromagnetic methods, we can gain understanding of the reservoir behaviour away from the borehole and on a larger spatial scale. The further we can ‘see’ into the reservoir the better we can proactively manage the production to maximise hydrocarbon recovery and minimise risk, waste, and cost.
Special focus will be in the use of distributed fibre-optic sensing (DxS), which include: Distributed Acoustic Sensing (DAS), Distributed Temperature Sensing (DTS), Distributed Pressure Sensing (DPS), Distributed Strain Sensing (DSS), and new types of distributed measurements. Distributed fibre sensing technology is a relatively recent but rapidly advancing technology that has seen accelerated use over the last several years in a variety of applications. In contrast to traditional point sensors, the fibre itself is used as a sensor. No electronics have to be placed into boreholes or other zones with high temperature or high pressure, enabling reliable long-term and time-lapse data acquisition in targets formerly inaccessible or impractical. Various temporary and permanent deployment schemes allow flow, temperature, seismic wave fields and other measurements to be recorded efficiently, opening up new avenues in reservoir characterization, production or stimulation monitoring.
We will highlight the latest advances of fibre technology, as well as encourage discussion on challenges related to sensing hardware, deployment, processing, integration and analysis. This workshop, through presentations, e-posters and participant interactions, attempts to capture the spectrum of fibre use and applications, give a snapshot of the state of the technology, and provide a view of the road ahead.
We encourage operators, service providers, researchers and users to share their experiences, successes and challenges when utilizing fibre sensing for a particular reservoir objective. Consumers of sensing information are encouraged to share their views or case studies on perceived or actual value of information or return on investment.
