A downhole seismic array comprising:
- a load-bearing cable;
- a series of seismic sensor units arranged along a length of the load-bearing cable, wherein each seismic sensor unit is attached to the load-bearing cable via a vibration-absorbing material and has a magnet to attach the seismic sensor unit to a well casing.
A downhole seismic array comprising:
- a load-bearing cable;
- a series of seismic sensor units arranged along a length of the load-bearing cable, wherein each seismic sensor unit has a magnet with a separate low-friction layer to attach the seismic sensor unit to the well casing.
A seismic array comprising:
- a load-bearing cable having multiple stops arranged along a length of the load-bearing cable;
- a series of seismic sensor units, each seismic sensor unit being releasably connected to a respective stop of the load-bearing cable via a vibration-absorbing material.
