      Highlights

      Deep technological know-how

      Sercel has over than 60 years of experience in the design and manufacture of marine sources for all types of surveys, from towed-streamer and OBN/OBC to VSP projects.

      The design philosophy behind all our marine source products is ease of use, safety, and reliability.

      Our source solutions are built for flexibility and long-term performance. They adapt easily to any operating environment and can be upgraded to integrate future source systems and in-sea technologies such as float systems.

      G-SOURCE II: delivers high performance and reliability in the toughest conditions of shallow and deepwater marine surveys

      GI-SOURCE: designed to reduce and suppress bubble oscillation from a single impulsive source, providing the best peak-to-bubble signature and simplified processing for all types of marine surveys.

      Mini G-SOURCE and Mini GI-SOURCE: scaled-down versions of the  G-Source and GI-Source models, ideal for high-resolution, shallow-water, and transition-zone surveys.

      Solution Insights

      G-SOURCE and G-SOURCE II

      G-SOURCE

      The system of choice for advanced VSP surveys in onshore environments. The G-SOURCE and Delta Cluster combine the advantages of a powerful source and a clean acoustic signature to maximize borehole data quality.

      G-SOURCE II

      The most advanced impulsive source in its class, delivering exceptional performance even under the toughest conditions. Its compact size, adaptability, and superior peak amplitude, higher than any conventional impulsive source, make it the ideal choice for advanced marine seismic surveys.

      • GI-SOURCE

      This source reduces and suppresses bubble oscillations from a single impulsive source, simplifying data processing. The GI-SOURCE is based on the same technology as the G-SOURCE but differs by featuring two independent air chambers within the same casing: the Generator, which produces the primary pulse and creates the main bubble, and the Injector, which injects air into the bubble to make it collapse more quickly.

      • Mini G-SOURCE and Mini GI-SOURCE

      The Mini G and Mini GI are scaled-down versions of the already compact G and GI designs. They are optimized for transition zones and ultra-shallow-water environments. With volumes ranging from 12 to 60 cubic inches, they deliver a high primary-to-bubble ratio for sharp, clean acoustic signatures. Their simple operation, lightweight frames, and easy deployment make them ideal for high-resolution shallow-water surveys.
