Sensitivity Analysis of Hydraulic Parameters on Cuttings Transport Efficiency in Underbalanced Drilling Operations

Underbalanced drilling (UBD) in depleted carbonate reservoirs employs multiphase aerated fluids whose compressible nature makes prediction of cuttings transport difficult. Inadequate hole cleaning is a leading cause of non-productive time, with poor hole cleaning responsible for one-third of all stuck-pipe events glo...
