Custom Worksteps
Custom Worksteps
The Ocean API lets you create custom worksteps that the end user integrates into
workflows. For example, a custom workstep might upscale log values into a pillar grid
property using an algorithm not currently available within Petrel.

Your main responsibility is to write the algorithm that does the work. Ocean helps you
access input data and create output data. Ocean even builds input UI’s for you, although
you can create a custom dialog UI if you need to.
To show how to write a custom workstep, we will implement a workstep to create a new
property from upscaled well log values.
The custom workstep takes a well log and a pillar grid as input and produces a new pillar
grid property along with its cell count (the number of cells in the new property).

In our workstep example, we will cover:
• Defining the workstep inputs and outputs
• Getting the input data into the workstep
• Setting the output data
• Default UI’s supplied by Ocean
• Providing a custom dialog UI
