The curved shape of BroadSeisTM streamers delivers the optimal signal-to-noise ratio at low frequencies for more quantitative and reliable inversion results, simplified interpretation and detailed facies discrimination. This delivers more accurate reservoir models, so enabling better development plans and improved ROI. The low frequencies are also crucial for Full Waveform Inversion for better velocity models and clearer imaging.
Exceptional images from wavelets without sidelobes
Improved facies discrimination for better architecture definition
Amazing stratigraphic detail for more accurate interpretation
Low frequencies are ideal for FWI and detailed velocity modeling
More accurate volumetric analysis from delineation of fine detail
More reliable and quantitative inversion attributes
The inclusion of low frequencies reduces the sidelobes of the wavelets, so that each peak or trough represents a real change in acoustic impedance, clarifying interpretation. Low frequencies also add "texture" to the data, making layer differentiation easier and simplifying correlation across faults, as well as providing stunning images.
The streamers are towed deeper in BroadSeis than in any other towed-streamer broadband configuration, the profile generally varying from around 7 to 50m, with an average depth of 40m compared to 20-25m for multi-sensor streamers. The deeper tow of BroadSeis provides the best low-frequency content of any towed-streamer broadband solution
The stability of the low frequencies can be ensured by 3D designature using signatures estimated from recordings at the near field hydrophone using FSC (Full Source Characterization).
