Overview
Independent oversight from survey design to final stack.
We provide client representation and quality control across the full seismic acquisition and processing chain, onshore and offshore, 2D, 3D and 4D. From survey-design review and vendor selection through to Pre-STM, Pre-SDM and broadband processing QC, we ensure data is fit for purpose and value-for-money.
- Survey design reviewIndependent review of survey geometry, fold, offset and azimuth distributions, and source/receiver configurations against imaging objectives.
- Vendor selection & tenderingTechnical evaluation of acquisition and processing tenders, vendor capability assessment and contract-negotiation support.
- Cost / benefit analysisTrade-off analysis between survey parameters (fold, bin size, azimuth) and cost, to optimise spend against business objectives.
- Client representation - offshoreOn-site or remote client representation during marine acquisition campaigns, including daily QC reports and decision support.
- Client representation - onshoreOn-site client representation for land acquisition, including HSE oversight, recording-quality QC and progress reporting.
- VSP acquisition & processingBorehole seismic survey design (zero-offset, walkaway, walkabove, 3D VSP), acquisition supervision and processing QC.
- Pre-STM processing QCParameter testing, milestone reviews and final-product QC for Pre-stack Time Migrated seismic processing.
- Pre-SDM processing QCVelocity-model QC, focusing analysis and well-tie QC for Pre-stack Depth Migrated seismic processing.
- Broadband & deghosting QCQC of broadband acquisition outputs and deghosting algorithms (towed-streamer and OBN) to maximise bandwidth and resolution.
- 4D processing QCRepeatability QC, NRMS analysis and 4D-friendly processing parameter QC for time-lapse projects.
- OBN & OBC oversightOcean-bottom node / cable acquisition and processing QC, including positioning, water-layer demultiple and PZ summation.
- Independent technical auditIndependent technical audit and second opinion on existing or completed processing projects, with documented findings.
