Fig. 5.4 Main challenges of a manual workflow compared to the benefits of an auto-
mated workflow.

oil losses and gains for a field with 100 wells or more could require a person
to enter values manually into a spreadsheet or database calculator 3 h or
more. Alternately, an engineer could use a spreadsheet or other software
coupled directly with a historian (which gathers the necessary production
data) and uses a batch-allocation process to reduce the total time consider-
ably. However, using cloud services, data analytics, and high-performance
computer power, this process can be fully automated and calculated contin-
uously and in real time.
From our collective professional experience, most E&P workflows can
be seamlessly automated, particularly those workflows related to production
monitoring and surveillance, diagnostic and analysis of production events,
