Casing, liners and cementing for Slim Hole Wells
As a well is downsized the collapse and internal pressure ratings of the surface and intermediate casing and liner string increase. Thus liners can be used further up the hole than with conventional hole sizes. This gives the downsized conventional approach to slim wells the capability to increase the diameter efficiency of wells.

"Diameter efficiency" of wells is a term focusing on the technical efficiency of the process of drilling and completing a well. The concept is to see how efficiently the inputs, money and time . . .
