2.8.0 - September 11th 2025

The team have been busy working on a release that brings powerful new mapping features, smarter well management, and improved forecast accuracy.

Interactive Well Map

  • View your wells on a dynamic map with latitude, longitude, toe position, measured length, and azimuth.

  • Add overlays to visualize additional spatial data for deeper insights.

  • Great for development planning, analysis, and field layout reviews.


Virtual Wells

A Virtual Well is a simulated or synthetic well created within the system to support modelling, forecasting, and decision-making. It allows users to run what-if scenarios without requiring measured field data, making it especially valuable in early planning stages or when testing conceptual development options. By configuring user-defined parameters such as production rates, decline assumptions, or reservoir properties, Virtual Wells help teams explore outcomes under different development strategies.

For Virtual Wells, we capture both the well position (latitude and longitude) and the bottomhole location—commonly referred to as the toe in horizontal wells. This allows wells to be placed on a map in a way that shows how they interact spatially with existing or planned wells. This visualisation supports development planning, including evaluating well spacing, minimising inter-well interference, and optimising field layouts for maximum recovery and efficiency.

In upcoming releases, Virtual Wells will be enhanced with analysis from other modules, such as Type Well analysis, enabling users to benchmark performance, compare alternative development strategies, and generate richer insights. Ultimately, Virtual Wells help organisations de-risk investment decisions, reduce planning costs, and accelerate time-to-value by testing ideas virtually before committing resources in the field.


We have enabled two modules (TAHK: Coal Seam Gas (PSS) Forecast and KOLDUN: CSG Monte-Carlo) for this release, where the user can generate forecasts using model inputs. Production Data is not required for a virtual well, therefore no history match is performed in virtual wells.

  • Virtual Well supports:

    • Forecasting undeveloped wells

    • Scenario testing and future planning

    • Full-field simulations

  • Can use hypothetical or averaged model properties (e.g., permeability, pressure).

  • Place spatially on the map or clone from a Type Well to model specific scenarios.


RULON: Roll-Up

  • Wells in the module are now sorted by well name for faster and more intuitive navigation.

  • Initial rates from RTA, FMB, and WOR forecasts have been corrected, delivering more reliable results for your analysis.


GAZ: autoFMB and MASLO autoFMB


GAZ: autoRTA and GAZ: autoRTA

  • export to csv button now added to forecast tab

  • a faster algorithm is implemented for calculating Bourdet derivative of large datasets


SPAD: Gas Decline and SPAD: Oil Decline

  • The Auto update smart-fit will not be automatically performed every single time the user initialises the SPAD Decline module.

  • If the dataset updates, the user needs to press the APPLY UPDATES for decline parameters update (module performs a new smart fit based on the new data)
