For larger surveys, feasibility testing can be run in-house to establish optimal parameters prior to passing the full dataset to a partner company to run the main production processing.Custom-built testing and sequence development, along with small-volume production processing – (using Shearwater Reveal & GLOBE Claritas software) – providing a truly individual processing service.Seismic Data ProcessingĮPI’s data processing team take pride in their ability to reprocess difficult datasets, offering advice, investigations and reports on many aspects of image related services. All analysis is performed by highly experienced processors using state of the art software. Turnaround is typically 24 hours from receipt of sample data and a comprehensive report is provided highlighting any areas of concern.

Check the EBCDIC header for SEG-Y standard conformance and completeness/accuracy of contents.ĮPI provides a secure file transfer facility (SFTP) via dedicated server where a client or contractor can upload data for verification, alternatively we can download data from a client’s server.Positional headers are cross checked against values read from the navigation data. For every header the following is also checked where appropriate: Min/max values, Min/Max increments, Number of zero samples, Check for NaNs for floating point numbers, Maximum number of consecutive traces with the same value.Check seismic data can be read and reformatted and the data looks as expected.Verify shot flags/fired status examine depths, pressures, volumes and timing delays examine separations, laybacks and tow skew & examine seismic RMS attributes for source balance.Įxamine separations at every offset examine depth at every offset examine bird wing data for angles and steering forces examine RMS noise attributes at each receiver. Navigation First Line QCĬheck P2 and P1 data formats, analysis of positioning networks, verify headers, check geodetic parameters, process raw data and compare to P1.Įxamine geometry and stability of spread, examine contract tolerance adherence of spread, & deviation of various nodes from preplot. To this end EPI offer the following services: 1.

Optimum Shooting Plan and Cost Analysis (SurvOpt Acquisition Planning Tool).Įxample images taken during the survey design process Marine Seismic Survey First Line QC ServiceĮPI recommend that all seismic and navigation data are subjected to an independent analysis and verification prior to commencement of all marine seismic operations, at specific stages (start of survey, re-configuration) and prior to deliverables being archived.Īn integrated deep-dive into data integrity, formats and quality is undertaken to ensure that data is being recorded and delivered according to industry standards.

2D Elastic Wave Equation Modelling (OMNI Workshop).

3D Geological Modelling and Illumination Study (OMNI Workshop).

3D Layout and Geometry Diagnostics (Schlumberger OMNI software).

EPI undertakes a full suite of modelling, utilising the following procedures into our design flow: Using subsurface de-risking methodology incorporating both proprietary techniques and fundamental methods developed by Vermeer, Cordsen and Galbraith to produce survey designs and parameters that don’t just focus on the imaging but provide a robust solution. Survey DesignĮPI specialise in robust survey design, perfectly suited to the specific needs of any project. EPI’s Applied Geophysical Solutions team offer a suite of survey design, processing, and quality control services covering onshore, offshore and transition zone seismic survey data acquisition and processing.
