Scope of well completion
Well completion means the conclusion of a borehole that has
been drilled. Completion is therefore the link between the
borehole and the production phase.
It involves all operations to make the well produce
- Connecting the borehole
- Treating the pay zone
- Equipping the well
- Putting it on string
- Accessing it
Measurement and maintenance operations (workover jobs) also
come under the heading of completion. Completion begins
with well positioning and ends at well abandonment.

Why well completion is so important ?
Increase asset value through cost optimization - well
completion cost represents one of the major
contributor to total wells expenditure in field
development
To provide subsurface and surface flow control
To effectively drain out the reservoir fluids to the
surface - increase productivity and recovery
