FIBER OPTIC SEISMIC VECTOR SENSORS (FOSVS)
The Paulsson FOSVS is an optical accelerometer capable of recording seismic events smaller than Moment Magnitude of M-6 in the field with an energy smaller than 1 micro Joule at frequencies over 10,000 Hz.
LARGE-ARRAY 3D/4D VSP (3D VSP)
The Paulsson Large Array Optical Seismic Sensors allow for cost effective 3D/4D VSP data acquisition.
LARGE-ARRAY CROSS-WELL SEISMIC (CWS™)
The Paulsson Large-Array Optical Seismic 3C Receiver System, deployed in one well, will in combination with the new large bandwidth seismic source, form an effective cross well seismic imaging system.
SINGLE-WELL SEISMIC SYSTEM (SWSS™)
Paulsson has created a unique and proprietary non-destructive clamped 3C borehole non-destructive vibratory seismic source. This development is part of creating an effective high-frequency large-bandwidth single-well optical seismic imaging system. The system combines the Paulsson 3C Fiber Optic Seismic Vector Sensors (FOSVS) and our new borehole seismic vibratory 3C source. The source-receiver system has been tested at frequencies from 5Hz to 1,600Hz with a 3,200Hz potential. Applications include imaging targets far from the instrument well, up to 6,000 feet (2km), essentially creating an ultra-long range 9C seismic logging system.

LARGE-ARRAY PRESSURE SENSORS (DPS)
The Paulsson proprietary Large-Array All-Optical High-Temperature Pressure Sensors can be integrated with all borehole sensor and source systems. This unique sensor allows Paulsson to deliver a full set of critical operational and reservoir parameters with one system deployed once.
DISTRIBUTED ENHANCED ACOUSTIC SENSORS (EDAS™)
The Paulsson Large Enhanced Distributed Acoustic Sensor Arrays are integrated with all borehole point and disrtibuted sensor and source systems.
DISTRIBUTED TEMPERATURE SENSORS (DTS)
The Paulsson Large Distributed Temperature Sensor Arrays are integrated with all pipeline and borehole sensor and source systems.
DISTRIBUTED STRAIN SENSORS (DSS)
The Paulsson Large Optical Strain Sensor Arrays are effectively deployed on or near pipelines, providing protection for fault or landslide movements. Another application includes instrumenting the casings during completion of wells.
