(Equipment / Material)
Model Number: BSR
Condition: New
Location or Storage Country: Russia
Service Engineering Support: Yes
Warranty: No
Price: Call for price
Description:
Standalone 4-component bottom-based recorder
Overview:

Digital module:
- BSR probe (Borehole Seismic Receiver Array)
- 24-bit ADC x 4-channel in each "shuttle"
- The ultra-low noise ADC allows recording low-amplitude microseismic events, 3D-VSP, seismic interwell transmission, etc.
- Probe with an outer diameter of 1.6 inches (<41 mm) for small wells
- Mutually perpendicular 3C sensors
- High Performance OMNI-2400 Geophones
- The turned stainless steel case minimizes resonance for recording with high resolution and frequency
- Separate modules are interconnected by an armored cable or rigid connecting rods with stranded conductors
- Flexible or rigid connectors can expand to increase module spacing
- Maximum distance between modules - 100 meters
- Maximum temperature - 150 oC
- The maximum pressure is 20,000 psi. inch
- Ability to place up to 480 3-component modules in the well
- Placement in vertical, deviated and horizontal wells
- The design of the housing may vary depending on the specific application.
