Our commitment to world-class services includes significant investment in configuring our crews with the most technically advanced data acquisition equipment. It is our aim to implement new operational approaches for imaging subsurface reservoirs, manage equipment and processes to keep costs down, and attain maximum productivity.
Leading-edge seismic recording technology provides high acquisition efficiency and timely delivery of quality data to our customers, even when conditions are challenging.
RECORDING SYSTEMS:
• I/O (ION) System - 10,000 Channels@2ms, Expandable to 30,000Ch
VIBROSEIS EQUIPMENT:
• INOVA AHV4-362 Vibrator Buggy with Series 60 Engine Up to 66,000 lb
Energy Source Control:
• Pelton Advance III VIB PRO
With its field proven reliability and ability to generate accurate sweeps, whether operating in sand or hard surface environments, Vib Pro sets the industry standard for vibrator source controllers and remains the most common controller in the industry today.
Vib Pro’s system architecture supports reliable, highly productive operations. Specific features of the system’s architecture and telemetry system enable:
• Accurate fundamental ground force control
• Optional integrated GPS
• Redundant storage of QC data eliminating missed sweep information
• Contractors to manage multiple vibrator fleet operations
• Parameters to be configured from the recording truck
Vib Pro enables seismic contractors to generate highly accurate source signatures demanded by oil & gas companies in order to deliver seismic images of the highest quality.
Explosives:
• Pelton SHOT PRO
• Compact for versatility of installation
• Internal/External GPS capabilities
• GPS navigation of crew and shot sites
• Decoders store shot data for up to 500 shots, retrievable by the recorder at a later time
• Compatible with Shot Pro, Advance II and Vib Pro for quick and easy transition between vibroseis and dynamite operation
• Operates with most commercial radios or wireline link
• Precise Uphole Geophone and Cap line resistance test
• Digital filtering of the uphole signal provides for an accurate first break pick and enhanced display.
• Analog timing marks and uphole signal are made available for recording by the seismic acquisition systems, and for verification of the synchronization timing
• Quality control shot status message automatically transmitted to the recorder
GEOPHONES:
• ION SM-24
•Tight specification, low-distortion geophone
• Extended spurious over 240 Hz, allowing full bandwidth at 2-ms sampling
• Backwards compatible with SM-4, SM-4 SuperphoneTM range, and SM-24ST
•Horizontal element available for shear-wave and 3-C recording.
•3-year non-prorated warranty
• Lowest lifecycle cost of ownership in the industry
• Installed base of over 8 million worldwide (est.)
The SM-24 geophone element is designed to offer the highest performance in seismic exploration based upon field-proven I/O Sensor technology. Low distortion, combined with excellent specifications, provide high-fidelity data in 2-D and 3-D surveys. The extended bandwidth allows the full potential of 2-ms/24-bit recording systems to be realized.
The tight specifications, unique element design, and exceptional quality of the Sensor SM-24 make it the lowest life cycle cost of ownership geophone in the industry.
• Applications: 2-D & 3-D seismic exploration with bandwidth from 10 Hz up to 240 Hz.
