monodiameter Liner & clad

The most efficient way to get through trouble zones.

Enventure’s SameDrift™ lets you extend a casing string to isolate trouble zones, while keeping the same ID. You can either tie back to the previous casing or simply clad the zone – or both. This ground-breaking technology will help you get through zones more efficiently than ever before.

Install SameDrift as Your Next Casing String and You Get the SameDrift as Your Base Casing

SameDrift has two major applications in the drilling process:

Extend casing strings – only requires the operator to plan for a shoe receptacle.

Isolate multiple trouble zones – multiple clads can be installed, without losing ID.

Benefits and Features
SameDrift’s Extends a Casing String to Isolate Trouble Zones, While Keeping the Same ID

  • No Reductions in ID
  • Modular
  • Provides mechanical barrier for cement & well control
  • Rotation & reciprocation.
Minimize Risk, Maximize Value

Maintaining the same drift means you can reach your total depth at planned or larger diameter.  And because it’s a solid expandable, it isolates trouble formations right the first time, reducing NPT.

SAMEDRIFT™ Specifications

SameDrift is currently available in 6 1/2", 8 1/2" and 12 1/4" post expanded drift sizes. The standard 12 1/4" system utilizes our 11 3/4" 47 lb/ft liner and is also configured to utilize out High Performance/Collapse 11 3/4" 74 lb/ft liner.

See the links to the left for specifications on each size.



SameDrift features a number of advantages all of which contribute to your bottom line.


Since the same tool is used for both openhole casing extension and openhole clad, it can be stored onsite for quick use in either situation.



Expansion takes only one trip, which lowers NPT.

Conventional drill out

The SameDrift shoe is drilled out with conventional techniques allowing you to continue drilling downhole.

Uses CLEAR™ expandable/retractable cone technology

Because SameDrift maintains the same diameter, it provides two great advantages for your drilling equipment:

After it’s installed you can continue to use your existing drilling configuration.

This also means you don’t end up with an atypical diameter requiring you to source drilling equipment using unique sizes.
