Seismic equipment manufacturer Sercel has announced the successful large-scale deployment of its seismic data acquisition technology on a mega-crew survey being conducted by Sinopec Geophysical Co. (SGC)
The survey, which covers large areas of Saudi Arabia, started in late 2019.
A wide range of Sercel equipment is being used to meet this project’s requirements, including more than 60,000 channels of Sercel’s 508 XT land-based seismic acquisition system and a fleet of more than 45 Nomad 65 Neo all-terrain vibrator trucks and VE464 advanced vibrator electronics.
With more than 50 systems deployed worldwide, the Sercel 508 XT simplifies field operations and offers full monitoring capabilities, its cross-technology architecture (X-Tech) optimises productivity and makes it the ideal choice for such mega-crew configurations.
When combined with Nomad 65 Neo vibrators and the VE464’s unique Smart LF function, accurate high-resolution data can be generated and recorded at low frequencies (down to 1Hz). This allows for a more detailed broadband seismic image and attributes without the noise issues that would otherwise arise.
Capitalising on Sercel’s advanced technology, SGC engineers on the mega-crew survey have been able to maximise productivity while capturing and recording data of the highest quality.
Zhou Song, SGC president, said, “Sercel’s contribution has been pivotal to this project’s successful implementation. Furthermore, we were able to quickly ramp up our operations, reaching target VP figures within the first few days of commencing activities.”
Emmanuelle Dubu, Sercel CEO, said, “This project showcases the high-resolution, high-productivity capabilities of our hardware as well as its unmatched scalability and adaptability. Its inherent robustness is designed to withstand the extreme temperatures and uncompromising working conditions encountered in the Saudi Arabian desert, thereby mitigating any downtime concerns.
“Given the success of this 508XT system in Saudi Arabia, Sinopec is already deploying a second 508XT system with 25,000 channels on another project in China.”
