3D Coil Shooting on Tulip field: Data processing review and final imaging results

The Tulip 3D survey is a single-vessel full-azimuth Coil Shooting project in Indonesia. The circular geometry is very different to the conventional race-track towed streamer approach. While it results in many acquisition and imaging benefits, it also introduces a number of new challenges in the survey design, modeling, acquisition and processing workflows. This paper presents an overview of the data processing / imaging experience made during the coil shooting project. A processing workflow was tailored to address the challenges, and at the same time taking advantage of the opportunities provided by the circular geometry. The resulting images are demonstrably far superior to the vintage seismic data in the area, and provide a more suitable dataset for AVO inversion to seismic attributes and reservoir property characterization.

Depth Imaging Coil Data: Multi Azimuthal Tomography Earth Model Building And Depth Imaging the Full Azimuth Tulip Coil Project

Summary The Tulip 3D is a full azimuth single vessel Coil shooting survey in Indonesia. Coil geometry acquisition records a dataset with a wide range of source to detector azimuths. Amongst the numerous benefits of extended azimuth sampling methods is the advantage of illumination diversity. This has a desirable impact with tomographic velocity model building for depth imaging. The broad range of source to detector azimuth information allows an additional constraint on the travel time tomography by providing a network of intersecting rays not available with narrow azimuth geometries.
