Webinar: Depth Conversion Without Velocities

In this webinar we will look at how to convert a TWT grid to depth when no velocity data is available.

 

Using two different methods available within Petrosys, we will:

  • Use the new cross plot function and the Spatial Editor back interpolation functionality to back interpolate TWT data to an Excel spreadsheet already containing depth data.
  • Using the resulting line of best fit formula between the TWT and Depth data, we will use grid arithmetic to depth convert the TWT grid to depth.
  • We will then look at using Kriging with External Drift (KED) algorithm to perform a depth conversion using the TWT grid and well location depth data as our inputs.
  • Finally we will compare the results to a depth grid created using the velocity data of the area to compare the results of the first two methods with the conventional depth conversion result.
