Thermal simulation of two-phase flow in under-balanced drilling operation with oil and gas production

The accurate prediction of wellbore temperature distribution helps to accurately estimate well pressure profile and bottom-hole pressure (BHP) which is important in the under-balanced drilling (UBD) operation. In this paper effect of temperature variation due to heat transfer of drilling fluid with the formation and also oil and gas production from the reservoir into the annulus in under-balanc...

Two-phase Boundary Layer Flow, Heat and Mass Transfer of a Dusty Liquid past a Stretching Sheet with Thermal ‎Radiation

‎The problem of two-phase MHD boundary layer flow, heat and mass transfer over a stretching sheet with fluid-particle suspension and thermal radiation has been studied. The effect of mass transfer in dusty fluid over a stretching sheet is considered for the first time. The governing equations are reduced to a set of non-linear ordinary differential equations under suitable similarity transforma...

Two-phase Flow Measurements by Nuclear Magnetic Resonance (nmr)

We pioneered NMR studies of concentrated suspensions starting in the late 1980’s (Majors, et al., 1989; Altobelli, et al., 1991; Abbott, et al., 1991). In those studies, we measured concentration and velocity of the liquid component in either in pipe or Couette flow. If we compare these early studies of suspensions with more recent ones (Hampton, et al., 1997), imaging time has gone from 40 min...
