It also ensures that there isn't any seepage of oil or natural gas out of the well hole as these are delivered to the surface. is the process of using electric devices to repeatedly measure the properties of a formation, to be able to make selections about drilling and manufacturing operations.
The properly designer should trade off the additional tools, complexities and risks towards the potential capital savings when deciding whether to design for a liner or a casing string that goes all the way in which to the highest of the well (a 'long string').

In competent formations, the zone may be left entirely bare, but some sort of sand-management and/or flow-control means are normally integrated. This refers to the portion of the nicely throughout the manufacturing or injection zone.
