Summary

Maximizing lateral length while minimizing costs associated with a new wellbore has been a goal of the industry for many years. The trend in horizontal drilling is to have progressively longer laterals within the pay interval. This paper will address one of the major issues associated with extended reach laterals (ERL): the ability to overcome wellbore obstacles and install casing to measured depth (MD) of the wellbore. This paper describes a method for installing open hole multistage (OHMS) tools that has been developed and run successfully in the DJ Basin in Colorado for ERL wells.
