Overview
The majority of operations are available as both a workstep and a process, and in these
cases end users have a choice of which one to use.

Fig. 6-21 Operations Available as Both a Workstep and a Process
Both worksteps and processes help the Petrel end user execute the necessary workflow,
depending on the operation or execution style needed. They use the workstep version to
build a workflow that can be saved and executed repeatedly and use the process version
when only a single operation is needed.
Processes are a bit more flexible than worksteps because they can be interactive.
Interactive operations such as well correlation and seismic interpretation are only available
as processes.
You can use the Ocean API to create both custom worksteps and custom processes. Both
are ways to extend the Petrel workflow to provide propriety algorithms for improved
reservoir results.
When you add your custom algorithm, you must decide whether to use a workstep, a
process, or both. You must decide based on how your operation fits into the workflow of
the Petrel end user.
