Hasan is currently working as a professor at Texas A&M University, after serving as a Professor in chemical engineering at the University of Minnesota, Duluth, from 2002-2011. He has established a world-class research program in wellbore heat transfer and fluid flow, publishing a definitive book on the subject in 2002. Hasan’s current interests include heat transfer models for subsea completion in deep water settings; modeling transient flow of heat, mass, and momentum in wellbores; analysis of warmback data to improve DTS visualization and interpretation, and alternative energy sources such as metal hydrides for energy storage and biodesels. He earned a BS in chemical engineering in 1972 from the University of Eng.

In Dhaka, Bangladesh, a MS in chemical engineering in 1975 and a PhD in chemical engineering in 1979 both from the University of Waterloo in Waterloo, Ontario, Canada. Shah Kabir is a global reservoir engineering advisor at Hess Corporation in Houston. His experience spans more than 30 years in the areas of transient-pressure testing, fluid- and heat-flow modeling in wellbores, and reservoir engineering. Kabir coauthored the 2002 SPE book Fluid Flow and Heat Transfer in Wellbores and contributed to the 2009 SPE monograph Transient Well Testing. He holds a master’s degree in chemical engineering from the University of Calgary.

Kabir has served on various SPE committees, including the editorial review committees for SPE Production & Facilities, SPE Reservoir Evaluation & Engineering, and SPE Journal. He was a 2006–2007 SPE Distinguished Lecturer and became a Distinguished Member in 2007, and he received the 2010 Reservoir Description and Dynamics Award.

With the development of drilling technology to deeper stratum, overflowing especially gas cut occurs frequently, and then flow regime in wellbore annulus is from the original drilling fluid single-phase flow into gas & liquid two-phase flow. By using averaged two-fluid model equations and the basic principle of fluid mechanics to establish the continuity equations and momentum conservation equations of gas phase & liquid phase respectively. Relationship between pressure and density of gas & liquid was introduced to obtain hyperbolic equation, and get the expression of the dimensionless eigenvalue of the equation by using the characteristic line method, and analyze wellbore flow regime to get the critical gas content under different virtual mass force coefficients. Results show that the range of equation eigenvalues is getting smaller and smaller with the increase of gas content. When gas content reaches the critical point, the dimensionless eigenvalue of equation has no real solution, and the wellbore flow regime changed from bubble flow to bomb flow. When virtual mass force coefficients are 0.50, 0.60, 0.70 and 0.80 respectively, the critical gas contents are 0.32, 0.34, 0.37 and 0.39 respectively. The higher the coefficient of virtual mass force, the higher gas content in wellbore corresponding to the critical point of transition flow regime, which is in good agreement with previous experimental results.

Therefore, it is possible to determine whether there is a real solution of the dimensionless eigenvalue of equation by virtual mass force coefficient and wellbore gas content, from which we can obtain the critical condition of wellbore flow regime transformation. It can provide theoretical support for the accurate judgment of the annular flow regime.
