GEOPET Well Completion and Stimulation 4
Once the design well depth is
reached, the formation is tested
and evaluated.
To complete the production well,
casing is installed and cemented,
and the drilling rig is dismantled.
A service rig is brought in to
perforate the production casing
and run production tubing along
with downhole equipments.
Production begins after surface
safety equipment installation
inished.

WHAT IS COMPLETION?
Well completion creates a
dependable pathway to the surface
for the hydrocarbons.
The term ‘completion’ describes
the assembly of downhole tubulars
and other safety equipments that is
required to enable the safe and
efficient production of oil or gas
from the well after it has been
drilled.
