Fiber Seismic Acoustic

Operational principle

Point sensor (i.e. - seismic

transducer) that transforms

seismic signal to an optical

signal

Distributed sensor (fiber dubs

as a sensor)

Sensitivity High Low

MagiQ’s current product is an ultra-high temperature (up to 300OC) micro-seismic sensor. Unlike Distributed Acoustic Sensing (aka - DAS), seismic provides high-fidelity vector signal that can unambiguously determine event location.

Comments

We design the entire system vs. being de-pendent on other suppli-ers

Old design, low max T, not profit-able

Buys interrogators from a competitor (Optiphase, owned by Halliburton)

Non exclusive license for interro-gator (Northrop Grum-man)

MagiQ vs. competition

MagiQ makes both sensors and interrogators, i.e. we do not depend on

third party suppliers for any critical components. This approach lets us to

optimize the sensor at the system level, i.e. better performance for lower

price.
