business solutions that economically grow our business while reducing emissions. We are committed to using our global leadership in carbon management to advance a lower-carbon world. Visit for more information.

We are looking for an experienced and motivated individual to fill the position of Geophysicist within our Geoscience group based in Houston, TX.

Essential Job Responsibilities:

  • Efficiently apply innovative and off the shelf practical workflows to improve the quality of Oxy's processed seismic data.
  • Run post-migration pre-stack processing of 3D seismic surveys (onshore and offshore) starting from raw migrated gathers using novel processing workflows to generate improved stacks and gathers.
  • Developing new workflows to improve subsalt amplitude fidelity, collaborating closely with our QI geophysicists and asset team interpreters.
  • Apply fit-for-purpose post-stack cleaning and enhancement workflows for interpretation.
  • Generate attributes for interpretation.
  • Identify and fill gaps in our current processing workflows. Develop bespoke workflows for improved imaging, and develop best practice workflows.
  • Work with WesternGeco to implement efficient Omega processing workflows at Oxy. Share learnings with Oxy geophysicists working with Omega processing software.
  • Run PSDM migration of onshore seismic data using existing PSDM velocity model starting from migration input gathers.
  • Demonstrate the application of novel demultiple techniques on challenging projects, having first run quick synthetic tests demonstrating proposed demultiple approach.
  • Work closely with QI team to ensure processed data are ready for QI studies.
  • Mentor junior team members, review their work and guide them to successful project completion.
  • Generate reports and presentations demonstrating value of seismic processing.
  • Collect and maintain set of best practice workflows from existing projects, document and make available for training purposes.
