  • 体彩河北11选5开奖查询:Dovetail

    Efficient Streamer Acquisition of High Quality Data

    后一万能码 2期内中 www.qgqx.net Dovetail? is an efficient streamer acquisition solution, especially where there is significant and unpredictable feathering. Dovetail significantly reduces the need for infill while remaining within bin fold specifications, leading to reduced survey time and HSE exposure and faster data receipt, with no degradation of data quality.

    Dovetail spread

    Why Use Dovetail?

    Dovetail combats poor far-offset fold coverage due to extreme feathering, caused by such things as strong local currents etc, by using three interlinked components:

    • Acquisition: 
      • Fan-Mode streamer acquisition by Nautilus, which can be programmed to produce a fanned spread automatically 
    • Variable Bin Expansion (VBE) 
      • applied to onboard binning to facilitate vessel steering for maximum coverage. 
    • Processing: 
      • Trace interpolation using an intelligent anti-leakage Fourier algorithm
    fold specs

    Benefits

    • Meets binfold specifications for survey with a drastic reduction in infill/prime ratio (current pattern-dependent)
    • Reduced survey time
    • Faster data receipt 
    • Reduced HSE exposure 
    • No reduction in data quality 
    • Reduced infill means less “wasted” duplicate acquisition and therefore increased processing efficiency 
    • Smaller holes in the data for safer interpolation 
    • Better sampling at mid/far offsets 
    • Large reduction in real-time steering/overlap 
    • Sail for pre-plot/near offset to achieve higher resolution

    Interpolation

    Since higher frequencies are attenuated at longer offsets and greater depths, Dovetail allows larger interpolation distances at longer offsets by increasing the streamer separation towards the tail of the streamers. Using a de-aliased anti-leakage, irregular Fourier transform and an advanced algorithm for the interpolation means that there is no degradation of the data.

    REVIVE5D uses the true source and receiver locations of the data, preserves amplitudes across offsets and azimuths accurately, and thus honours the true 3D character of the data (important in areas of significant feather).

    Dovetail seismic

    It is impossible to tell where the data was acquired using “Dovetail” and interpolation, or where using conventional acquisition with over 40% infill. The final fold after interpolation is the same for both the conventional and the Dovetail acquisition.
