A New Model to Determine the Two-phase Drilling Fluid Behavior Through Horizontal Eccentric Annular Geometry, Part A: Flow Pattern Identification and Liquid Hold-up Estimation

Osgouei, R. E.; Ozbayoglu, E. M.; Özbayoğlu, Ahmet Murat; Yuksel, E. H. (Taylor &Francis Inc., 2015)

Flow patterns, liquid holdup, and frictional pressure gradient are three importance parameters to study the multiphase drilling fluid behavior. Although two-phase fluid flow is studied in detail for pipes, there exists a ...
A New Model to Determine the Two-phase Drilling Fluid Behaviors through Horizontal Eccentric Annular Geometry, Part B: Frictional Pressure Losses Estimation

Osgouei, R. Ettehadi; Ozbayoglu, E. M.; Özbayoğlu, Ahmet Murat; Yuksel, E. H. (Taylor & Francis Inc., 2015)

Drilling with aerated muds is becoming more often used in underbalanced drilling operations. One of the major challenges that has to be faced in such operations is the estimation of the physical behavior of aerated fluids ...
