GVERSE® WebSteering is specifically designed to help geoscientists' geosteer horizontal wells in thin pay zones and to direct the drill bit in real time.

It is the only web browser based geosteering application in the industry that delivers optimal well placement with simple data loading and full integration with GeoGraphix. GVERSE® WebSteering installs in the web browser like a plugin and then it's simple to load curve and survey data from the rig, add type logs and subsurface grids from GeoGraphix®, and start steering within minutes. At any point, data can be sent back to GeoGraphix for further analysis using GeoGraphix's feature-rich suite of tools. GVERSE® WebSteering runs even when disconnected from your corporate network so whether you are in the office or working remotely, you can define your target surface and send updated drilling targets to the rig.

GVERSE® WebSteering is a complementary tool for GeoGraphix users who can sync their interpretations on-the-fly with their GeoGraphix projects and update their target surface in smartSTRAT®** . This application lets you stay ahead of the drill bit with real-time information accessible from anywhere.

Release Key Highlights

  • Reverse logarithmic and linear scale for secondary curves
  • Option to add additional survey point to project LWD beyond the bit
  • New licensing options for network licensing and daily use through GVERSE Go
Add Type Logs and Well Data to GeoGraphix
Select or drag-and-drop LAS files containing type log information. On the Add Type log pop-up enter UWI, Longitude and Latitude, Elevation information, and select the desired curve as well as survey file.
Add Proposed Surveys to GeoGraphix
Select or drag-and-drop excel files containing survey information. Also map the desired excel file columns and either select the landing point station or enter the landing point MD. A new proposed survey ID is assigned by WebSteering to the imported proposed survey in GeoGraphix.

Set the Depth Interval of a Type Log
Define a top and bottom offset on the Depth Interval pop-up, the type log selected on the Type Logs tab is clipped automatically and available to view in Dashboard.

Dynamically set the extents of type log from Survey plot
Now the vertical extents of all type logs will adjust itself automatically according to the vertical clipping of the survey plot.
Marker Beds for representing drilled formations
Formations encountered in the drilling well can now be represented in the Survey plot of the Geosteering page. Length and % Zone of wellbore inside the market bed is also calculated.
With the help Marked Beds, Geosteerer can quickly visualize formations encountered in the drilling well and can also get the length and % Zone of wellbore inside the drilled formations.
Cross section view of wellbore drilling inside marker beds. Length and % Zone of marker beds encountered by drilling well.
Formation Selection from User-defined Source List
Formations that are selected from the LWD or Type Log tab are fetched from the Source List that is created by users in GeoGraphix.
This provides the user to limit the number of selected formations according to the selected source list.
Selection of "Source List" from "Source List" drop down in "Setup" page. LWD curve displaying formations fetched from Selected Source list
Support for Z-Map+ Files
Z-Map+ files can be loaded and then displayed on the GeoSteer page. This helps in displaying grids that are in Z-Map+ format and are stored outside GeoGraphix.
Z-Map+ Grid loaded in the "Surfaces" tab and displayed on the "Survey" plot of "Geosteering" page.
Performance improvements and Usability Enhancements
a) Performance Improvements on "Grid" Loading operations
Significant performance improvements have been made in grid loading operations. Also the workflow for managing large grids has been improved. Grids with less than 2 million points can be loaded without any errors. For grids exceeding this limit, a message displays prompting the user to decrease the grid resolution. With faster grid loading user can now easily load grids, calculate the length and % Zone of drilled wellbore inside the grid and then switch to Geosteer page for geosteering.
Length and % Zone calculated for multiple grids which are also displayed in Survey plot of Geosteering page.

b) Usability Enhancements on Loading and Saving WebSteering Interpretations
Measures have been taken to improve the saving and loading of big geosteering sessions. A Progress Bar is now displayed to show the status of saving or loading operation.
Now loading and saving of WebSteering interpretation is extremely fast and any WebSteering interpretation can be loaded and saved very efficiently.

Support for NAD27 US Survey Feet Projections and additional Datum Transformations
GVERSE WebSteering now supports NAD27 Survey Feet Projections. Moreover, Magna-Sirgus, WGS84, Egypt 1907 and NAD (27) Michigan datum are also supported in WebSteering.
With the implementation of these new projections and datum transformations, GeoGraphix projected created using these projections and datums are now supported in WebSteering.
Additional Datum Transformations listed in "Datum" drop down box of "Setup" page.
Improvements in Zooming Operations
Zooming In with Right mouse button
To zoom into any graph, use your right mouse button to select the area on the graph.Separate controls are now available for Zooming In and modifying the dip of the segment. Now Zooming In Operation is done with Right mouse button while segment correlation is done with Left mouse button.
Zooming In on Type log graph with right mouse button.

Automatic expansion of the graphs for accommodating new survey or LWD data.
The Survey and LWD graphs expand automatically on importing more data. Expansion of extents is based on MD values of the imported survey or LWD data. With the implementation of automatic expansion, the need to modify the extent every time when new survey is imported has been minimized. Survey and LWD graphs automatically expand according to the input data.

Target Line Parameters
Parameters for target line can be editable by entering the exact values on the Target Line Tool pop-up. When these parameters are changed Target is adjusted automatically on the graph according to the entered values.
Editable target line parameters provide additional controls for defining the trajectory of the target line.
Editing of Inclination parameter for modifying the trajectory of target line.
