UK 31st Offshore Licensing Round

Integrated geophysical reprocessing services and multiclient data

For the 31st Offshore Licensing Round, the Oil and Gas Authority (OGA) is offering more than 1,766 blocks covering 370,000 km2, including many underexplored basins in the UK Continental Shelf. There is a vast library of narrow-azimuth towed streamer heritage data for this area that can be reprocessed using new technologies to reveal greater insights into the geologic features of the basin.

WesternGeco offers reprocessing services that use the latest geophysical algorithms and workflows. We also have a wide array of 2D data is also available from our extensive multiclient library to help you fill in any data gaps, select an optimal 3D survey location, or even reprocess to achieve a fit-for-purpose result. 3D data is available in the Moray Firth Basin to enhance your drilling decisions in this area.

Whether you have already put in your tenders for the available blocks or are still conducting your prospectivity assessments, we have the right geophysical product or service to help you make the best possible decision.

Fill in your data gaps with 2D and 3D data

WesternGeco has more than 213,700 km of 2D data to help you enhance your prospectivity assessments. We are also currently planning a broadband reprocessing prestack depth migration (PSDM) survey in the Moray Firth Basin covering 4,450 km2. The objective of this survey is to reduce uncertainty in the structural image and improve signal-to-noise ratio and amplitude reliability. If you have bids on open blocks in this area, this data provides some of the highest-resolution images available on the market today to help support your drilling decisions.

Maximize the value of your 2D or 3D heritage data with reprocessing

With the constantly evolving developments in geophysical technology, reprocessing helps you extract the most value from your heritage 2D or 3D data.

We offer integrated reprocessing, imaging, and inversion workflows to address the issues associated with heritage datasets and the geological and geophysical challenges of the basin.

Improve seismic bandwidth with broadband processing

Our latest data conditioning workflows, including adaptive deghosting and 3D shallow-water multiple attenuation, give you improved resolution, reduced noise and multiple contamination, and better input for depth imaging and inversion.

Reduce interpretation uncertainty through imaging with multiples

Our approach to imaging with multiples eliminates crosstalk, which reduces your acquisition footprint and compensates for the lack of near angles recorded with typical towed-streamer geometries to provide you with reliable images for the interpretation and characterization of the shallow section.

Generate complex earth models with full-waveform inversion

With full waveform inversion (FWI), mature models, low frequencies, and long offsets are no longer required to produce high-resolution velocity models. Our FWI algorithms help you overcome your model-building challenges, greatly improving image quality, especially in the shallow waters of the UK Continental Shelf, where complex overburden geology is common.

Least-squares migration in the image domain

Least-squares migration in the image domain (LSM-i) uses point spread functions (PSFs) to correct for the spatial variation in illumination frequently observed in heritage datasets. After correction with LSM-i, seismic amplitudes are less affected by acquisition geometry and overburden geology and better reflect changes in subsurface properties. The result is a more reliable inversion to rock properties, ultimately reducing uncertainty in reservoir characterization.
