Methods for minimizing the amount of graphite particles used during drilling operations, the methods comprise performing drilling operations using a drilling fluid system having effective rheological and fluid loss control properties, the drilling fluid system comprising a mixture of graphite particles having an effective particle size distribution.

Methods for minimizing the amount of graphite particles used during drilling operations

Drilling fluid systems, graphite particle mixtures, and methods for use thereof including: (a) drilling fluid systems having effective rheology and lubricity properties comprising a suspension of graphite particles having a particle size distribution sufficient to permit greater than 65 wt. % of the graphite particles to pass through a shaker screen having a mesh size of about 80 or less; and (b) spotting fluids having effective rheology comprising graphite particles having an average particle size of 120 mesh or greater.
