... on a performance motor BHA to enhance the ROP. The hybrid bit enhanced the ROP by 153% with a 52% reduction in cost per foot compared to the average TCI performance in this field, saving the operator 2.2 days and over $ 0.4 Million operational cost. The hybrid drill bit design demonstrated its ability to serve...

..., and even blades ring out. A recent campaign on SMK introduced two new 12-1/4" bit designs. First, a Hybrid bit (Roller Cone – Fixed Cutter PDC) was selected following a positive global experience on hard formations. A second trial involved a PDC with a Conical Diamond Element profile in the secondary...

... types, a 16 inch hybrid bit was proposed to answer the challenge of drilling the section as fast as a PDC bit while providing the stability, torque control and smooth hole condition generated by a roller cone. Selecting an appropriate hybrid design to match the application resulted in an initial trial...

.... Hybrid drill bit technology, roller cone combined with Polycrystalline Diamond Compact, was introduced in search for an economically viable solution to deliver wells faster and achieve yearly operator targets. This paper analyzes the breakthrough drilling performance achieved by a 22 inch hybrid bit...
