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.

Well tie 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.

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.

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 DimensionsOnce it is activated, it will propagate the same settings across all the wells.

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

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

Save TemplateThe 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 WellThis will allow the user to add any additional wells.

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

Add New TrackIt will add an empty track

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

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

MARKERS VISIBILITYAll 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.

Functional panel allows user to perform the following actions:

open Visual Settings panel

adjust view area to all visible objects

set/unset zoomable

set control item

add Object

enable mouse tracker

enable tool tip

export picture

ruler tool

show compass

show minimap

show scale bar

Residual trace

Alongside the synthetic seismogram, the well tie view can display a Residual seismogram (residual trace), computed as the difference between the synthetic trace and the seismic trace at the well location (synthetic minus seismic). It is calculated only within the footprint of the synthetic overlay, so its extent matches the synthetic trace window. A flat, low-amplitude residual indicates a good match between the synthetic and the seismic, which makes the residual trace a convenient quality-control display for the tie.

The residual seismogram is generated automatically together with the synthetic trace and appears under the corresponding well in the Data Manager (in the time domain), so it can be added to the view like other seismic overlays.

Drift curve

When you edit the checkshot anchors, a Drift curve - the difference in two-way time (ΔTWT) between the adjusted checkshot and the base checkshot - is generated automatically and shown in the display, and is saved as a LAS curve under the well. See Well Tie for details.

An example of a well-to-seismic tie, along with a detailed description of the required data, can be found in the Best Practice Flows - > Well Tie section
