International Advancement of Drilling Bits for Oil and Gas Well (2) —FuseTek Bit and Pexus Hybrid Bit

Abstract:

FuseTek bit, a PDC Impregnated diamond hybrid bit, launched by NOV in 2013. It is suitable for drilling medium-hard to hard and abrasion formations. The FuseTek bits were widely used in Congo, Ecuador, China, Colombia, etc., Applications have shown that the FuseTek bits could increase the ROP obviously and bit life 1-3 times or more compared with PDC bit or roller cone bit . Pexus hybrid bit, a PDC Carbide hybrid bit, launched by Shear Bits in 2014,which used extensively in Western Canada to drill glacial till, comprised of a hard top layer of boulders, drilled by rotary carbide element and a soft bottom layer of sand and shales drilled by PDC cutters. The whole interval can be drilled in one run with one Pexus bit. Those three types of hybrid bits are significant for realization of “one bit, one well” in the future.
