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.
