Permanent Downhole Seismic Sensors in Flowing Wells

It is generally accepted that the ‘Oilfield of the Future’ will incorporate distributed permanent<br>downhole seismic sensors in flowing wells. The effectiveness of these sensors will be limited by the extent to<br>which seismic signals can be discriminated, or de-coupled, from flow induced acoustic noise originating<br>within the production tubing,<br>A specialised test facility has been developed in order to understand and characterise the acoustic<br>noise generated by fluid flow within a production borehole, with the goal of developing the next generation<br>of seismic tools suitable for permanent deployment in flowing wells.
