Brochure: DTO Wellhead

The DTO "Drilling Time Optimization" wellhead system uses remarkably efficient components as part of an innovative design, saving as much as 20 hours of rig time on each well. The reduction of rig time translates into thousands of dollars of savings for an operator, especially when applied to multi-well drilling programs that are repetitive and predictable. The DTO Wellhead system is easier to install than a basic conventional wellhead because of its creative utilization of technology.

In several real- world applications, the DTO Wellhead has dominated large-volume, infield-drilling programs across North America. With the combination of a new drilling spool connetion, landing ring, mandrel casing hangers, and tubing head bottom connection, the DTO Wellhead eliminates the following steps common to conventional wellhead installation:

• Cutting and draining the conductor
• Rough cutting and prepping the surface casing
• Welding the casing head
• Nippling up the blowout preventer flanged connection
• Waiting on cement
• Nippling up the tubing spool flanged connection.
