WELCOME TO ECHELON RELEASE 2024.1

The Stone Ridge Technology team, along with our development partners at Eni are pleased to announce the latest release of the ECHELON software, version 2024.1. The key new features are described in more detail below:

Coal bed methane model for black-oil

ECHELON now supports gas adsorption and desorption to and from organic matter in black-oil formulation; both time-dependent and instantaneous models are available. The feature is referred to as ‘Coal bed methane’ but can also be used for modeling shale gas formations.

Extended RESQML support

ECHELON now supports the reading of grid properties directly from RESQML epc files through a dedicated READ keyword. This reduces the effort required to run unstructured models generated by third-party geomodeling software such as Petrel™.

Conditional scheduling capabilities

Look-up tables are now available in the SCHEDULE section to be used in the evaluation of user-defined quantities (UDQs).

Connection and Region-types UDQs are now supported, in addition to the previously supported Field, Group and Well UDQs.

Custom mobility model for injecting connections

The default model for computing the mobility applied to injecting connections (based on the total connected cell mobility) can be overridden to be more representative of near-wellbore conditions.

Extended pressure maintenance model

Pressure maintenance controls now supports assigning target pressure for any set of fluid-in-place regions.
