Specialists in Depth Conversion and Seismic Inversion software for the Oil & Gas, CCUS and Offshore Wind industries
We have been developing depth conversion and seismic inversion software for over 20 years. Our products link with both the Petrel and Kingdom geoscience platforms and are a cost-effective investment, enabling you to achieve an unparalleled level of accuracy in understanding the subsurface.
We are partners with S&P Global, who retail our products around the world as VelPAK and Seismic Inversion on the Kingdom platform and Velit on the Petrel platform. We are also the sister company of ERCe, giving us unrivalled access to expertise and global project experience.



Velit sets the industry standard for achieving accuracy in depth and properly quantifying your P10/P50/P90 reserves estimations. Our ‘constrained stochastic’ methodology enables you to automatically generate 1,000 depth models, varied around your Best Technical Case model, which are summed together to determine a highly likely understanding of the subsurface.
Minimize Your Risk
Accuracy in depth is crucial to ensuring that your drill bit comes in on target, potentially saving $millions versus a misplaced well. You can also calculate the economics of your prospect to
ensure that the decisions you make in the subsurface are robust and correctly position geohazards to minimize the risk of a rig blow out.
Leverage Well & Seismic Velocity Data
Velit uses an extensive library of industry-standard velocity modelling methods using well velocities or seismic processing velocities to create accurate depth maps, even from sparse data. The easy-to-use Wizard and Workflow systems enable you to optimize your operational efficiency.

Kingdom Seismic Inversion includes Colored Inversion, Simulated Annealing Inversion, EEI Inversion and Pre-Stack Inversion and provides you with a high-quality product, an easy-to-use interface and an operationally efficient workflow. Our toolset is perhaps the ideal complement to your existing inversion workflow, enabling you to complete a ‘quick look’ feasibility analysis.
Post-Stack Inversion
Our Colored Inversion tool enables you to quickly generate a pseudo-relative impedance model and is ideal for seismic interpretation. Simulated Annealing generates a true relative impedance model as well as absolute acoustic impedance models.
Pre-Stack Inversion
If you have shear sonics available, then you can separate your hydrocarbons from your background geology and then characterize your reservoir by its gas, oil and water content. Our package enables you to compute a number of elastic parameter transformations, which are suitable for conventional and unconventional prospects alike.


LogToVolume is a general-purpose property spreading tool, which enables you to create a volume of any petrophysical log property, as well as being able to propagate velocities in a geologically consistent manner. This toolset has particular application for upscaling velocity models to encompass anisotropy and provides macromodels as input for Kingdom Seismic Inversion.
Depth Conversion
Handles Complex Velocity Models: LogToVolume can handle more complex and irregular velocity models compared to conventional depth conversion techniques and can accommodate lateral velocity variations and velocity anomalies that are commonly encountered in real-world subsurface scenarios.
Property Spreading
Applicability and Efficiency: LogToVolume uses a guided Wizard interface, which can streamline the depth conversion and property spreading processes and save time for geoscientists and engineers. Additionally, our software tools are so easy to use, these processes are now more accessible to a wider range of users.
Testimonials
“We are a gas and infrastructure operator focused on becoming a material developer and producer in the Southern Gas Basin. Understanding depth conversion uncertainty and quantifying resource range is critical for our business. Velit was the best depth conversion tool we found that allowed us to identify the drilling locations carrying the least geophysical risk and quantify the range of possible outcomes.”

Our Strategy
We thrive in an environment whereby we can work together with you as partners, to solve geophysical problems associated with depth conversion and seismic inversion, and develop new technology as a result. While evaluating our toolsets, we welcome the challenges associated with continuous innovation and build trust by routinely delivering on what we have promised.
We invest in the personal development of our staff to maximise their full potential, with this focused on the relationship we will build with you, rather than just the sale of our products.
Software Design Philosophy
Our design philosophy is geared toward developing software which is both reliable and sophisticated, easy to use and applicable to every level of user experience. This is achieved by the development of software Wizards that guide you through various workflows, resulting in improved operational efficiency of your tasks.
One of the key elements of our packages is the adoption of a ‘No Black Box’ approach, which enables you to examine, adapt and add to the methods, according to your requirements.
