In this topic, we will apply the effective mud density formula to determine maximum ROP before fracturing formation.
Figure 1 – Max ROP before Fracturing Formation
These two equations that will be used to determine the maximum ROP are listed below;
Effective mud density due to cuttings in the hole can be determined by the empirical equation below;
ρeff is effective mud density in ppg.
ρm is mud density in ppg.
Q is flow rate in gpm.
ROP is rate of penetration in fph.
db is wellbore diameter or bit diameter in inch.
