Abstract
A downhole seismic array is disclosed. The array comprises a load-bearing cable for carrying a series of seismic sensor units arranged along its length. 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 the well casing.
Claims16
A downhole seismic array comprising:
- a load-bearing cable;
- and
- a series of seismic sensor units arranged along a length of the load-bearing cable, each seismic sensor unit comprising a seismic sensor and a corresponding magnet to attach the seismic sensor to a well casing,
- wherein each seismic sensor unit is configured such that each seismic sensor is attached to the load-bearing cable via a vibration-absorbing material, and each seismic sensor is attached rigidly to the corresponding magnet, and
- wherein each sensor unit comprises a partially-open channel with an elongate curved opening to allow the load-bearing cable to be inserted into, and removed from, the partially-open channel in a bent configuration, such that when the load-bearing cable is straightened within the partially-open channel, the load-bearing cable is securely attached to the sensor unit.
