Saudi Aramco is developing gas fields in various areas utilizing vertical and horizontal wells with rotary as well as motor BHAs. This application requires Saudi Aramco to drill laterals through an extremely tight sandstone formation with inclination varying anywhere from 72° to 90°. The highly abrasive formation is causing inconsistent PDC bit performance while drilling the 5 7/8-in. horizontal section resulting in exceeding the authorization for expenditure (AFE) of the wells. Saudi Aramco, in collaboration with the bit company, analyzed the field data, which showed extensive cutter damage, with abrasive wear being the most common dull characteristic. The cutter wear was causing short runs and frequent trips to change out the bit. A step change in bit design was required to extend bit life and increase rate of penetration (ROP) in areas where poor drilling performance is expected.
