What’s New in RMS 11.1?
Struggling with poor data? Not confident in your model?
With RMS 11.1, you can capture uncertainty throughout the interpretation process, generate multiple realizations, and build accurate and robust models with less data and in less time.
RMS 11.1, Emerson’s leading reservoir modeling software, contains
- new features and large enhancements (described in full in the Release Notes PDF document),
- many small enhancements and fixes to satisfy client requests and client-reported issues (described in full in the Improvements and Fixes PDF document).
Access these PDF documents from the RMS menu bar (Help ➥ Release Notes).
New Features and Enhancements for RMS 11.1
RMS 11.1 introduces new features and enhancements including, but not limited to, those described in the following subsections.
- RMS selection tools from the Data Explorer can now be used within Plugin panels. The available selector options include horizons, wells, and trajectories.
- It is now possible to set RMS plugins to sub levels in the RMS Data tree.
- Support for storing the state of check boxes has been enhanced. While previously, only the checked state was stored in the configuration, now the unchecked state is also stored, with the value
- The Roxar API has been enhanced to provide full access to grid geometry; users now are able to create or update grid models with custom grid geometry.
3D Grids and Property Modeling
Improvements to the Channels NGOM job (see also Channels Next Generation Object Modeling):
New method for editing the channel shape, and shape editors are now expanded in Edit mode.
Distributions can be visualized in a plot for easier QC of the input data.
New, and more intuitive, icons introduced to describe to which directions trends will be applied.
In the Volume fractions section, when setting the direction according to the grid layout, select between I, J, or K.
When using trends as input to geometries, the directions are set according to the channel azimuth; select between Along channel, Perpendicular to channel and In depth.
Minor performance issues has been addressed to further enhance the usability of the job.
The i-Task for creating logs has been converted to a job in RMS and renamed as the Create Blocked Well Log job; as such, this can now be incorporated into automated workflows to ensure repeatable results (see also Creating Blocked Well Logs).
Presentation, Flexibility, and Usability
Several enhancements further increase the effectiveness of the existing workflow management capabilities within RMS (see also Using Workflow Management):
- A tooltip has been added for Notes in RMS workflows; this tooltip provides the user name of the user who last edited the note, and the date and time of when the editing was made.
- In the Workflows Area, two new directional arrow buttons have been added which allow you to go back, and go forward, to previously visited workflows in a project session.
You can now display point data in an Intersection view.
You can now export multiple SEG-Y data using the Export SEG-Y dialog box as opened from the Seismic folder in the Data tree (see also SEG-Y Multiple Export), and also export individual objects in the SEG-Y format, as in earlier versions of RMS, using the Export Single SEG-Y dialog box (see also SEG-Y Single Export).
Wells and Logs
The new Blocked Wells Log Calculator (IPL) job enables you to create new blocked well logs, based on mathematical operations on existing blocked logs. The functions used to create new logs can be stored in the calculator and applied to different sets of wells, and also be stored as IPL scripts for future use (see also Blocked Wells Log Calculator (IPL)).
A new Log Smoothing job has been added, enabling you to smooth log curves in the log runs of trajectories (see also Smoothing Logs).
The i-Task functionality for combining logs has been made into an RMS job, such that it can be accessed by IPL scripts, for example, as part of workflow which can be automated (see also Creating a Combined Log).
The new Create Horizon Picks from Surface job allows you to create Horizon well picks relative to a selected surface, with respect to the stratigraphic framework of the project (see also Creating Horizon Picks from a Surface).
The Remove Duplicate Horizon Picks dialog box allows you to delete duplicate Horizon well pick types in a well with respect to the stratigraphic framework in RMS (see also Removing Duplicate Horizon Picks).
The new Create Collection from Log Filter job allows you to create an RMS Data Explorer collection based on filtered logs (see also Creating Collections from a Log Filter).
The Composite Parameter Convert dialog box has been extended to support user-definition of the date format as applied in the name of result parameters (see also Converting Composite Parameters).
3D seismic data in an RMS project has four subset items:
- Region of Interest
- Time or Depth
Multiple subsets can be created; using these subsets, you can investigate the seismic data by playing through the seismic cube using the Seismic Fence Player, and perform seismic interpretation directly using RMS’ Model Driven Interpretation functionality.
The Depth Convert Horizons and Depth Convert Faults jobs have been renamed as Domain Convert Horizons and Domain Convert Faults respectively.
Using these jobs, it is now possible to perform both Time and Depth conversions for horizons and faults data (see also Domain Converting Horizons and Domain Converting Faults respectively), including their surfaces, polylines and points (see also Domain Converting Points/Polylines/Surfaces).
The Horizon Uncertainty Modeling dialog box has been improved where, for Depth to Depth workflows, there is the possibility to directly output a Horizon model using the new From horizon and fault model option as the Model setup mode (see also Horizon Uncertainty Modeling).
Visualize density distributions in scatterplots with four available visualization effects, which can be applied individually or combined, to assist in gaining a better understanding of the density distribution for the data in the scatterplot (see also Scatterplot Toolbar and Density Tab).

Changes Affecting Existing Projects
This section describes changes which affect existing projects through the released versions of RMS 11.1.
Projects older than RMS 2013.1 are not accepted by RMS 11.1.
In accessing the license server to check for available RMS licenses, the environment variable now used for the address to the server is GEOMATICLM_LICENSE_FILE.
On the Windows platform, the FlexNet 11.14 licensing software uses the Local Service rather than the Local System account as used by previous versions of FlexNet. It is therefore required that an Administrator level user installs the service, but also that the Local Service account has appropriate Write permissions for the directory where the log file is located.
For the Channels NGOM job, the available trend input for Volume Fractions has now been limited to 1D trends to ensure correct use and representation of the trends. If other trends have been used in previous versions of RMS, the trend input will be set to No trends when loading the project containing those Channels NGOM jobs into RMS 11.1.
The Geometric Modeling job, when the Creating regions based on nearest well option is selected, has been updated to provide two modeling modes, Normal and Simbox. The previous Additional output option True distance in simbox has been removed from the dialog box. This could prompt some changes in existing projects.
As part of a redesign of all region functionality in RMS 11, generating a fault block parameter in the grid was transferred from the previous Create Grid Index Parameters dialog box to the new Create Region Partition dialog box.
The removal of the functionality in the old dialog box could impair workflows when upgrading projects. In RMS 11.1 the generation of a fault block parameter has therefore been reintroduced to the Create Grid Index Parameters dialog box. It is now possible to create a fault block parameter in both the Create Region Partition and Create Grid Index Parameters dialog boxes.
In versions of RMS earlier than 11.1, when adding uncertainties to a Geometric Modeling job using surfaces as input where the calculation type Height above surface was selected, uncertainty had to be set as constants. However these values were not taken into consideration when running an uncertainty study.
Setting uncertainty on surfaces has now been made available in RMS 11.1. Projects from earlier versions, with invalid constant input to the uncertainty, will therefore have this uncertainty removed when loading in RMS 11.1.
In RMS 11, running a Horizon Modeling job, for some cases of models with many conformal horizons with no isochores between the horizons, could exhaust resources such that RMS could fail to respond.
A modification has therefore been made to the default algorithm of the Horizon Modeling job to address such cases. Now, without input isochores, the algorithm will produce more continuous thicknesses across faults than previously; when running with input isochores, changes should be minor.
Scheduled Changes After RMS 11.1
The Facies Elementary job is scheduled for deprecation, given its functionality is covered by other facies jobs in RMS. Maintenance will not be carried out on this job after this release of RMS 11.1, and the removal of this job from RMS is planned for the near future.
The Facies Elementary job has no parameters that can be altered in a multi-realization uncertainty setting, making it unsuitable for a Big Loop or multi-realization scenario, in contrast to the other facies modeling jobs in RMS. The Facies Composite and newer Channels NGOM jobs both have superior functionality and flexibility, and should therefore be used as an alternative to, or a replacement for a Facies Elementary job.
