Tool Changes with RigStream

Tool Changes with RigStream

When a new GR tool is sent downhole with a different tool offset or requires a different GR scaling, you will need to create a "New Log" in the Well's RigStream settings and use the "New Log" as your “active” WITSML log. You will need to apply an End Time Filter to the "Original Log" and a Start Time Filter to the "New Log". Now you can apply the appropriate tool-setback or log scaling to each log set. This process ensures the interpretation’s integrity is maintained while dealing with the new setback distance or scaling.

Below is a detailed walkthrough of how to handle GR tool changes, mid-Well while using RigStream.

  • In the Viewer for the associated well, select RigStream Connection from the Well dropdown menu

Image
  • Under the Logs tab, click the “Add Log” button

Image
  1. Select the correct RigStream data and give the "New Log" an appropriate name

  2. Set a Start Time Filter for this "New Log", this will prevent the inclusion of data from the "Original Log". 

    • Start Time Filter: The day and time the new tool was put downhole

  3. Click “Ok” to create the new RigStream Log

Image
  1. In the Well Log Name dropdown, select the "New Log" and click the “Set Active” button

  2. Select the gamma-ray log in the list below

  3. Click the "Edit Curve" button

Image
  1. Make sure the gamma-ray log is selected, then input the "Sensor Offset" for the "New Log"

  2. Click "Ok" to save your changes

Image
  • Back in the RigStream Configuration pop-up window, choose the "Original Log" in the Well Log Names dropdown

  • Under the Date/Time Filter, apply an End Time Filter corresponding to when they changed tools

    • Note: The End Date/Time Filter for the "Original Log" should be before the “Start” time filter you applied to the "New Log"

Image
  • Double-check that the "New Log" is the “Active” log, then close out of the RigStream Connection pop-up window 

    • Note: The "Active" log will have "[Active]" after the log name

Making the new RigStream Curve the Active LWD Log:

There are two ways you can make this new RigStream Curve the active LWD Curve.

  1. Create a Splice Log and use the Splice Log as the LWD Curve (Recommended). See this article for more information: Creating a Spliced Log in ZoneVu

  2. Add this new RigStream Curve to the Geosteering LWD Curve list and set it as active and display the other RigStream Curve in the Vertical and Horizontal Correlation Tracks. See below for a walkthrough of this second option.

  • Open the Scene Control, open the Logs tab and make sure both the "Original Log" and the "New Log" are present

    • Note: It may take several RigStream updates to download all the data

Image
  • Now open the Geosteering Interpretation Settings and select the green "+" button next to the "LWD Curve" dropdown

Image
  1. In the Add/Remove LWD Curve pop-up, select the "New Log's" gamma-ray curve

  2. Click the "+" button to add the curve to the "Chosen" Logs

  3. Click "Ok" to save your selection

Image
  1. Back in the Geosteering Interpretation Settings pop-up, assign the "New Log's" gamma-ray curve as the active LWD curve by selecting it in the "LWD Curve" dropdown

  2. Click "Ok" to save your changes

Image
  1. Back in the Scene Control, make sure the "Original Log's" gamma-ray log is turned on in the Horizontal and Vertical Tracks

  2. Also make sure that the “Original Log's” and “New Log's" gamma-ray curves do not overlap and have consistent relative scaling 

    • Note: On the Horizontal and Vertical Tracks, the curve with the orange bar is the LWD Curve, the dark blue bar is the "Old Log's" gamma-ray curve, and the light blue bar is the Type Well Curve
