Eclipse 2025.1 release announcement
The new GTABPROD and GTABINJE keywords have been added to both Eclipse 100 (E100) and Eclipse 300 (E300) to allow concise specification of all group production and injection information in single keywords, with rows defined by their date of application. This is an alternative to the existing GCONPROD and GCONINJE keywords, which must be specified multiple times throughout the scheduling data.
Improvements have been made to support cases with component solubility in water defined by CO2SOL and H2SSOL keywords. Firstly, the default water density calculation now uses the Ezrokhi's method, a standard in such cases. Solubility calculations now employ exponential expansion for more precise interpolations of formation volume factor and viscosity.
Several enhancements have been made to line plot reporting in this version:

Eclipse 2024.1 release announcement
Date-ordered tabular input for satellite group production definition The new GSATPTAB keyword has been added to both E100 and E300 to allow specification of all satellite group production information in a single keyword, with rows defined by the date they are to be applied. This is an alternative to the existing GSATPROD keyword, which must be specified multiple times throughout the scheduling data
New and improved functionality
For both Eclipse 100 and Eclipse 300 simulator

For the Eclipse 300 simulator
A “direct” regrouping option that allows unconditional transfer of wells to a new group has been added. This will prove useful in several field management scenarios, such as regrouping wells to different manifolds, facilities, or production targets.
RFT reports for wells containing inflow control devices (ICDs) have been extended to include three latest items: ICD (inflow control devices) length, scaling factor, and maximum flow rates at segment conditions. These can be useful for quality checking the inflow performance for these devices and can be visualized from Petrel™ subsurface software.

Eclipse 2023.1 release announcement
Highlights
New user-defined argument (UDA) facilities
The following keywords include new items made available for definition as user-defined arguments in both ECLIPSE 100 and ECLIPSE 300 (unless otherwise noted):
GCONPROD – group production control
GSATPROD – satellite group production control
The use of expressions in these control methods allow, for instance, concise production decline curve type modeling.
Additionally, the alternative behavior for well and group quantities that can be specified by UDA in more than one keyword, previously available only in ECLIPSE 100, is now also available in ECLIPSE 300. Additional functionality has been added in both ECLIPSE 100 and ECLIPSE 300 for cases where a second keyword modifies a quantity rather than setting it directly.
Finally, UDA reporting has been improved to avoid situations where, if wildcards were used in a keyword, there was no confirmation that a particular UDA had been deactivated .
