Özet

Excessive torque is one of the most important problems in oil/gas drilling industry. Friction between wellbore/casing and drill string causes excessive torque. This study discusses performance analysis of drilling fluid lubricants, which are used as friction reducers in well-bores. Three different types of chemical commercial lubricants, which are fatty acid and glyceride based, triglyceride and vegetable oil based and polypropylene glycol based, diesel oil, and crude oil, which consists of different API gravities, paraffin and asphaltene value samples, are selected for the analysis.
