Abstract:
A reversible polycrystalline diamond compact (PDC) bit. The reversible PDC bit includes at least one blade, at least one front cutter disposed on a first side of the at least one blade, and at least one rear cutter disposed on a second side of the at least one blade, wherein the first side is opposite to the second side along a circumferential direction of the reversible PDC bit, wherein rotating the reversible PDC bit in a clockwise direction engages the at least one front cutter to cut into a subterranean formation, and wherein rotating the reversible PDC bit in a counter-clockwise direction engages the at least one rear cutter to cut into the subterranean formation.
