Casing shoes play an important role in well construction and completion. Casing shoes are specialized attachments or components that are installed at the bottom of casing strings or liners during drilling operations.

They provide protection to the wellbore and the surrounding formation during drilling. When drilling through unconsolidated or weak formations, casing shoes prevent the collapse of the borehole and maintain its integrity.

They help prevent the ingress of loose or unstable material into the wellbore, ensuring a stable drilling environment.

Casing shoes often include anchoring features, such as slips or mechanical devices, which help secure the casing in place. These anchoring mechanisms prevent the casing from moving or sliding during drilling and subsequent operations. Casing shoes also assist in centralizing the casing within the wellbore, ensuring even distribution of cement during the cementing process.
