US 2019/0169937 A1 · MODULAR REAMING DEVICE

Abstract

A modular reaming device incorporable into a tubular string. The modular reamer can include a tubular body having a first end and a second end and an internal bore, the internal bore extending longitudinally through the tubular body from the first end to the second end. The tubular body has an external surface with an outer diameter with cutting elements extending from the tubular body beyond the outer diameter of the tubular body for engagement with a bore hole sidewall. Each of the first and second ends have a coupling for coupling engagement with a tubular string.
