Well tie view

Top  Previous  Next

 

This view is designed for performing, analyzing, and visualizing the well tie process and its results. It consists of two windows: the first displays seismic and well data, while the second shows the cross-correlation function as a numerical outcome of the well tie analysis. This setup allows users to assess the alignment between seismic data and well logs effectively.

 

 

views_bar_well_tie_tab

 

Well time view is a customizable window where users can independently display the data they need for their work, such as log data, time-depth curves, seismic traces, and synthetic traces.

 

To configure this window, users need to go to the Well Tie bar in the Ribbon bar and select the data required for visualization. The user should have seismic data, well information (check shots/sonic/density/Impedance) to perform the seismic to well tie.

views_bar_well_tie_view

 

The newly created view will appear in the View manager in the active Workspase.

 

For visualization settings, users can right-click to open the Settings window for the currently active track.

 

The orange locks with the letters S and Z indicate the scale settings, allowing you to enable or disable scrolling and zooming, respectively, with or without pressing the mouse wheel.

 

views_bar_well_tie_axis_settings_tab

 

 

You can easily switch between the settings of each track without closing the settings window by simply clicking on the track you need.

The active track will be highlighted in blue.

Clicking on the top field with the well name activates the Global settings, which include the following list provided below.

You can also access the Global settings by right-clicking on the field with the well name, where you will also find the following functionality:

 

Propagate Well Dimension        Once it is activated, it will propagate the same settings across all the wells.

Fit Well to Content                It will fit all the wells to the same. It is kind of Zoomed out.

Full size mode                It will open a new window for print friendly image to print the well correlation.

Save Template                The user can save the whole setup as a template. You can select a saved template from the Well tie bar under Well Tie Template.

Add New Well                This will allow the user to add any additional wells.

Remove Well                        As the name suggest, the user can remove any wells from the display.

Add New Track                It will add an empty track

Zoom Speed on Shift        Adjusts zooming speed

Depth on Hover                Displays the MD when the cursor is hovered on the well log.

Curve Depth On Hover        Displays the curved depth of the well log.

Show Marker Values        Displays marker depth values of the well log.

Show Marker Names        It will show the marker names of the well log.

Marker Zoom on Hover        Enables zooming into markers when the cursor hovers over them.

Propagate Curve data        Enables the synchronization of curve data across multiple displays or sections, ensuring consistent updates to related curves when changes are made.

Axis Font                        Sets the font style and size for labels associated with axis.

Default Brush Size                Defines the default size of the brush tool used for marking or drawing on the display.

Frame Around Lithology        Adds a frame around lithology displays.

Linear Velocity                Defines the constant velocity used for converting time-based seismic data to depth or distance.

UI COLORS                        The User Interface (UI) to modify the color settings. When we click on it, it will expand. The user can change the foreground/back ground etc. To collapse it, just click on it one more time.

UI DIMENSIONS                These settings are related to the Tracks/Horizons/Check shot height and width dimensions. The user can modify as per their choice.

AXIS SETTINGS                Inside these settings, the user can ON/OFF the Markers/TWT/TVD etc.

MARKERS VISIBILITY        All the loaded markers appear here. The user have the complete control to display which one needed to be displayed.

 

 

The Cross-correlation view is essential for evaluating the alignment between well log data and seismic data during the well-to-seismic tie process. It displays the cross-correlation function, which quantifies the similarity between the synthetic seismic trace (generated from well logs) and the actual seismic trace. By analyzing the cross-correlation values, users can adjust the time-depth relationship to achieve the best match, ensuring accurate ties between well data and seismic reflections.
