The notion of a job is an important one when considering a well completion; it is through a series of jobs that the completion is actually built, modified, or removed.

However, exactly what constitutes or defines a job can vary widely from company to company. Figure shows several examples of common jobs—from both the operator/producer and service company perspectives—related to wellbore completions.

Figure Example well services jobs from both the producer and service company perspective.

The term job can be used to refer to everything from the entire scope of work required to install the completion (from the operator’s perspective), to one single task of that overall job, for example, perforating the well. There are typically jobs within jobs, which form a nested or hierarchical relationship.

To avoid the varying definitions of the common industry term job, the completion data object instead uses the concept of an event.
