• HYBRID ACQUISITION

Acquisition solutions combining towed streamer and ocean bottom node techniques delivering seamless subsurface insights to address our clients most challenging imaging objectives.

SPARSE NODE GRIDS

Combining a sparse, passive node grid with high resolution streamer seismic data provides common receiver gathers with long offset refractions which are ideal input for full-waveform inversion and multi-azimuth reflections to address anisotropy.  

TARGETED DENSE NODE PATCHES

Incorporating targeted dense node patches into a larger streamer survey complements the efficiencies of towed streamer surveys, with multi-component node data tailored to address specific imaging challenges.

NODE SWATHS FOR INFILL

For projects in congested areas with surface infrastructure and/or shallow water areas, node swaths provide seamless subsurface imaging where offsets from conventional dual vessel undershoots may not adequately illuminate targets. 

 

 

• SOURCE TECHNOLOGY

Tailoring the energy source used for seismic acquisition surveys enables the desired imaging objective to be optimized. Typical energy sources contain an array of volumes to best match the geological environment.

OPTIMIZED SPECTRA

A standard energy source array will produce an acoustic broadband output with frequencies peaking between about 6 to 200 Hz.

​To expand the signal bandwidth for both lower and higher frequencies PXGEO is utilizing innovative source technologies.

Using these technologies allows significant extension of seismic signal bandwidth for ocean bottom node and towed streamer surveys.  

BLENDED SOURCES

Traditional use of marine sources required sequential activation of one or more sources as the survey vessel progressed down a selected acquisition line so that reflected signals from successive shots did not interfere.

​With the recent development of robust data processing source de-blending techniques, multiple sources can now be activated in blended modes including overlapping in time or activated simultaneously. The use of blended multiple source techniques significantly increases 3D spatial sampling and trace densities while enhancing overall survey efficiencies.

​PXGEO has a wide range of experience in towed streamer and ocean bottom node survey designs using blended energy source techniques. 

MULTIPLE SOURCES

PXGEO's multiple source, XArray™ configurations provide improved in-line shot intervals and cross-line bin density on any streamer separation. These can be tailored to provide higher fold data, increase cross line sampling and/or improve acquisition efficiency.

​This is achieved using multiple sources, continuous data recording and ‘deblending’ algorithms to separate energy from overlapping shots.

APPLICATIONS

• 3D EXPLORATION

Highly efficient, large scale 3D seismic data acquisition is adapted to meet geological-specific imaging objectives. Flexible streamer, OBN and source configurations can provide high resolution 3D spatial sampling with high trace densities in both offset and azimuth.

​PXGEO has a wide range of experience working with clients to optimize their exploration objectives in areas such as the Gulf of Mexico, West Africa, Europe, Mediterranean, South America and Asia Pacific.

 

• 3D APPRAISAL AND DEVELOPMENT

Focused 3D seismic data acquisition in producing basins targets specific imaging objectives. OBN and streamer configurations can be combined to address specific imaging challenges while optimizing broader basin-wide geological understanding.

PXGEO works closely with clients in a number of producing basins worldwide including in Brazil, Australia, Asia Pacific, the North Sea and Norway to provide key insights to their appraisal and development activities.

 

• 4D PRODUCTION OPTIMIZATION

Repeated high resolution data acquisition enables the measurement of incremental subsurface changes over time. Enhanced applications of towed streamer and OBN techniques are particularly suited to complex geologies and obstructed areas.

PXGEO has extensive experience working with clients to optimize hydrocarbon production in such geographies as Brazil, West Africa and Asia Pacific.

 

• CARBON CAPTURE, UTILIZATION & STORAGE

Advanced subsurface imaging provides valuable insight for offshore Carbon Capture utilization and Storage (CCUS) strategies. CCUS is becoming increasingly important to mitigate the impact of greenhouse gas emissions.

PXGEO has experience in working with clients and governments to address their CCUS strategies in countries such as Norway, Japan, UK and Australia.

 

• OCEAN BOTTOM SURVEYING
