S-Cube delivering breakthrough X-Waveform-Inversion (XWITM) technology. 

Industry's leading sound waveform algorithm.
Next generation workflows to uncover every detail. Turn dark data into smart data.
Laying the foundations for a Net Zero, integrated offshore energy transition.

S-Cube Intro

We are a high-growth venture spinout from a world-leading research group at Imperial College London, focused on developing innovative technology which combines state-of-the-art sound wave segregation techniques with computational optimisation. 

X-Waveform-Inversion (XWITM) unravels raw sound waves from the earth to automatically reveal new understanding of the subsurface. It specifically targets sound waves reflected from the deepest interfaces within the earth where economically valuable natural resources lie hidden close to existing infrastructure.


S-Cube Growth and Energy Transition Milestones

Our growth needs to be directed to matching the needs of the energy transition and laying the foundations for an integrated, decarbonised offshore energy system for the North Sea and beyond.

Progress in XWITM has centred on:

  • Breakthrough optimisation toolbox for reflected soundwaves
  • Scalable cloud-native parallelisation to run the algorithm at scale 
  • Intelligent user interface for automated integrated workflows
2015- Theoretical Breakthroughs

2015- XWI Breakthroughs

Differentiated capability in sound segregation through advanced mathematical loss-function formulations which lead to the best possible predictive capability predicting unseen drilling logs. It is the continued innovations from Adaptive Waveform Inversion onwards which have set S-Cube’s soundwave segregation apart from day one.

2018: On Prem to Cloud

2018- Cloud Transition

Taking the leap beyond homogenous constrained on-prem systems. S-Cube were able to uniquely engineer AWS tools and capabilities to run XWITM cloud-natively at scale with a large dynamic pool of EC2 Spot compute. This enabled S-Cube to apply XWITM at scale and apply deep learning alongside classical optimisation to generate the best possible seismic image.

2019: First Cloud Pilots

2019- First Cloud Pilots

A collaboration between S-Cube, AWS and the operator to stress test the XWITM cloud architecture. This saw XWITM applied on a subset of a 2500km2 survey in a prolific activity hub in the central Atlantic. XWITM was used to keep all the data on the cloud, performing a frequency sweep going as high as necessary to get the required detail to unlock new understanding.

2019-: Optimisation Pilots

2019- Optimisation Pilots

Maintaining a laser focus on optimisation toolbox and uniquely-engineered loss function development through international pilots. Technology which proved discoveries but discoveries which proved the technology. Enhanced pre-drill predictive power, better decision-making and ready to transform the way operators do business.

2020: Intelligent UI

2020- Integrated Innovation

Taking XWITM to the next level with a differentiated UI and integration with off-the-shelf E&P platforms. Get access to results faster. Collaborate seamlessly. Start a new job with only an internet connection. Run leading software from your laptop. Start iterating the weights within minutes of plugging in inputs. Combine the best of human and machine intelligence with the best optimisation toolbox.

2020: OGTC North Sea

2020- Net Zero North Sea

S-Cube receive multi-million-pound grant as part of the Net Zero North Sea programme where XWITM will be used to optimally calibrate existing well infrastructure where current technology has failed. Partnering with AWS, S-Cube will deploy the optimisation toolbox to high-frequencies in this infrastructure-led project, paving the way for regional productivity gains, reduced footprint activity and repurposing of existing infrastructure for CCUS or hydrogen production.


XWI Sound Velocity Model Building


  • Fully data-driven optimisation framework for deriving the most detailed and accurate best-fit earth velocity volume from recorded seismic data. 
  • The XWI toolbox integrates the AWI and RWI cost functions for adjusting velocity values to predict seismic field recordings with CWI and GWI for conditioning and tuning.
  • The outcome is more accuracy, more predictive power, more automation starting further away from the true answer with a very wrong initial model.

Case Studies

Adaptive Waveform Inversion (AWI) was the theoretical breakthrough which led to the formation of S-Cube. Following the patented solution to a long standing problem in numerical optimisation, it was field trialed in 3 separate settings.

It was able to demonstrate automated global minimum convergence (prediction error minimisation) with gradient-based steepest-descent optimisation from multiple starting points without the need for human intervention.

In each case false local minimum convergence was avoided without the need for human-driven tomography.

Distinguished Awards

The first major application of time-domain waveform inversion incorporating anisotropic wave propagation was conducted by founding members of S-Cube, a study which received the 2013 Best Paper in Geophysics.

Just a few years later, Adaptive Waveform Inversion (AWI) was patented and became the recipient of the Bonarelli Award in 2015 by the EAGE, the leading European professional organisation in petroleum geoscience for the long-standing problem in localised optimisation it was able to provide a solution for. 

AWI was the start of a non-stop development and growth in the story of S-Cube. This has paved the way for S-Cube to gain technical and business recognition for commercial achievement and innovation at the forefront of the energy sector.
