Gemini Enhanced Frequency Source: Precision in Seismic Imaging
The Gemini enhanced frequency source offers a breakthrough in seismic data acquisition by providing unparalleled low-frequency bandwidth and enhanced operational efficiency, ensuring high confidence in subsurface imaging.
Unique 1-D Point Source Technology
Gemini is designed as a single-element, omnidirectional source optimized for imaging frequencies. Unlike traditional array sources, Gemini’s 1-D signature removes variability due to angle or azimuth, delivering more accurate AVO/AVA analyses and faster convergence in Full Waveform Inversion (FWI) algorithms. Its extended bandwidth—adding an additional octave of low-frequency energy—produces a clearer, crisper final image with reduced sidelobes, improving overall seismic clarity and interpretation.
- Generates more low frequency energy than standard airgun array
- Significantly lower energy above 200 Hz
- Operationally simpler
- Usable offsets exceeding 40 km
- Comparable energy for imaging up to 50 Hz
- Less acquisition downtime
- Point source simplifies data processing
Maximize Imaging Accuracy & Speed
- Higher Imaging Confidence: Achieve higher accuracy in AVO/AVA analyses with reduced uncertainty in source designature.
- Enhanced Velocity Models: Gemini’s low-frequency energy allows for better initial velocity models and faster FWI convergence.
- Superior Imaging: With additional bandwidth, Gemini produces crisper images with fewer sidelobes and more reliable 4D seismic acquisition.
- Efficiency in 4D Surveys: A simpler single-element source minimizes operational complexity, leading to fewer acquisition reshoots and greater consistency in 4D analysis.
Reduce Downtime & Boost Efficiency
- Reduced Downtime: With significantly fewer moving parts and a single-string towing setup, Gemini simplifies deployment and retrieval, minimizing downtime and enhancing overall operational efficiency quickly.
- Improved Safety: Fewer components and a streamlined towing configuration lead to reduced HSE exposure, ensuring safer operations.
Maximize Productivity and Improve Operational Resilience
Gemini's reliable and uncomplicated design ensures that when deployed with a spare on the vessel, any maintenance issues can be swiftly addressed with minimal disruption. This reduces reshoot times, maximizes productivity, and keeps operations running smoothly.
