  • Performance of permanently installed tubing conveyed seismic arrays using passive acoustic absorbers
    Patent number: 9470815
    Abstract: Methods and apparatus for reducing the impact of guided (or “tube”) waves in permanently installed seismic systems are provided. By utilizing passive acoustic absorbers, the impact of tube waves may be reduced, leading to improved performance of permanently installed seismic systems that are installed onto production tubing when the well is completed.
    Type: Grant

  • Apparatus and method for transporting, deploying, and retrieving arrays having nodes interconnected by sections of cable
    Patent number: 7036601
    Abstract: An apparatus and method for transporting, deploring, and retrieving an array is disclosed. The array has a plurality of nodes interconnected by sections of cable and can be transported, deployed, and retrieved with the apparatus and method of the present invention. The apparatus includes a plurality of first divisions and a plurality of second divisions. The first divisions have first portions or holders capable of individually accommodating the nodes. The second divisions are alternatingly positioned adjacent the first divisions. The second divisions have second portions or surfaces capable of individually accommodating the sections of cable. The first and second divisions can be integral portions of the apparatus, can be separate members positioned on the apparatus, or can be used with a standard cable drum. Preferably, the second divisions can be rotated relative to the first divisions to tightly wind and easily unwind the sections of cable.
