"CCED are currently acquiring the world’s largest 3D node survey over our blocks 3 & 4 (29, 219 sqkm), onshore Oman. This nodal technology approach (c.165,000 channels) provides multiple benefits to CCED, by cutting down on data acquisition costs, minimizing HSE footprints in the field (less manual handling, reducing vehicle count from c.160 to c.40, reduced field crew size 600 to c.220 etc.), and expanded land access in our sabkha-dune environment, all to acquire high quality, operationally efficient (high density, point receiver geometries providing increased spatial sampling density, with no compromise to data quality) outcomes."
This presentation aims to educate seismic practitioners about the practical aspects and business impact of high-density nodal acquisition using a real-world case study.
We present and analyse operational information and workflows from the project including: crew size, composition, logistics and HSSE; source and receiver productivity; survey and seismic data QC; and data transcription, delivery and processing.
The world needs high-density seismic imaging – but bulky, expensive equipment was stalling progress. That’s why we created the world’s smallest, lightest autonomous node.
