A hole opener ( 100 ) having a hybrid reaming section for reaming subterranean wellbores may include a tubular reamer body ( 103 ) having a longitudinal axis and upper and lower ends, a rolling cutter mount ( 108 ) coupled to the body, a rolling cutter ( 110 ) rotatably coupled to the mount, and a fixed blade ( 106 ) coupled to the body adjacent the mount. A method of forming a hybrid reamer tool for downhole use may include providing a tubular stem ( 102 ) having couplers on the upper and lower ends, coupling a reamer body having an outer periphery to the stem between the stem upper and lower ends, coupling a rolling cutter mount to the outer periphery of the reamer body, the mount having a rolling cutter rotatably coupled thereto, and coupling a fixed blade to the outer periphery of the reamer body adjacent the rolling cutter mount. |
