Insight Fiber Optic Downhole Tool
Insight by OptoSeis Fiber Optic Downhole System
PRODUCT DETAILS
Insight features three-component, all-optical downhole shuttles, specializing in multi-level, real-time, continuous, high-definition seismic acquisition.
Features
- Passive, all-optical downhole sensor network – no electronics downhole.
- Years-long operational lifetime @ 150 °C.
- 3-each high dynamic range optical accelerometers in each shuttle.
- Low noise, linear point sensing enables accurate recording of low-amplitude microseismic events.
- Slim hole shuttle 2.50-inch OD – less than 63 mm.
- Operates in any orientation.
- Solid-machined shuttle body minimizes mechanical resonance.
- High-resolution and high-frequency recording.
- Direct connection sub arrays, armored wireline.
- Magnetic and bow-spring clamps available.
- Supports wireline tools below the array (Gamma, CCL, Well Tractor).
- Distance between shuttles from meters to kilometers.
- Maximum temperature rating 150°C.
- Maximum pressure rating 20,000 psi.
- Capable of > 100 shuttle levels per well deployment.
- Compact, modular topside interrogator.
