Leapfrog allows you to view everything in a single 3D scene with an intuitive and logical workflow. The planned borehole tool is perfect for projects where you have existing models and would like to plan for future work and/or identify locations of uncertainty, where more data should be gathered.

Why Plan Boreholes in Leapfrog?

Planned boreholes were designed to allow you to evaluate models onto boreholes that have yet to be drilled, so that you may view and export a drilling prognosis for a set of planned boreholes. Outside of labor costs, drilling cores is often the most expensive part of a project. Planning boreholes will allow you to save drilling costs while preparing for the unknown.

How do you Identify and Plan for Uncertainty?

In almost all projects, a ‘lack of data’ can be identified somewhere throughout the project’s lifetime. How do you plan for uncertainty and make the most educated decision on where to gather data next? How do you plan for what you might encounter in the subsurface? The borehole planning tool gives you the answer to these questions. Use your planned boreholes to provide clients and colleagues with the necessary information they need to plan for what they might encounter. Identify locations of uncertainty and plan for the unknown using what you already know, your 3D model! Evaluate the model of your choice onto planned borehole locations to infer what you will encounter upon drilling. Whether you are lacking data in a location or you are dealing with complex subsurface structural, planning boreholes will help identify where you need more data and why.

How do you create planned boreholes in Leapfrog?

To create a new ‘planned borehole set’ you will want to right click on the ‘planned boreholes’ subfolder beneath the borehole data folder in the project tree and create a ‘new group’. You will also see the option to import planned boreholes from an existing .csv file. To start adding new planned boreholes, you will first select ‘add borehole’ and then chose the location of your collar or target on your model or on the topography in the 3D scene. You can also write in x, y, z coordinates if this is the method you prefer. You’ll then designate a ‘depth’ if creating a collar and continue the process for all planned boreholes. Once you’ve created a planned borehole group, you will want to right click on that group in the project tree and select ‘evaluation’ to display any models you’ve made on the boreholes.

After creating planned boreholes, you can either export this as an interval table or create a drilling prognosis to provide to clients and colleagues. A drilling prognosis allows you to see what lithologies or numeric values you will likely encounter and at what depths according to your geologic or numeric models.
