Experimental Study Of A Foam Flow In Horizontal Pipes: Two Flow Regimes And Its Implications, Miodrag Bogdanovic
Experimental Study Of A Foam Flow In Horizontal Pipes: Two Flow Regimes And Its Implications, Miodrag Bogdanovic
LSU Master's Theses
Although foam has been widely used in many scientific and engineering applications, the current understanding of foam rheology in pipes is still very limited because of its complex nature. This experimental study, for the first time, investigates the flow rheology of foams in pipes by placing a special emphasis on two distinct foam flow regimes. A wide range of experimental conditions are examined in this study, which include five different surfactant formulations (Cedepal FA-406, Petrostep CG-50, Stepanform 1050, Aquet TD-600, and Ultra-Palmolive), three different surfactant concentrations (0.1, 1, and 5 wt %), two different pipe diameters (0.5 and 1 inch …
Evaluation Of Sweep Efficiency Of A Mature Co2 Flood In Little Creek Field, Mississippi, Didem Senocak
Evaluation Of Sweep Efficiency Of A Mature Co2 Flood In Little Creek Field, Mississippi, Didem Senocak
LSU Master's Theses
CO2 displacement is the most widely used EOR process, but poor sweep efficiency and large CO2 utilization rates are limitations to the economic and technical success of CO2 floods. Developing a methodology to maximize the sweep efficiency and minimize the CO2 utilization rate would greatly improve the economics of these fields. This thesis evaluates the sweep efficiency of a successful, late-in-life, continuous injection CO2 flood at the Little Creek Field, Mississippi. In this work, we evaluate several heterogeneity measures in terms of recovery efficiency and utilization rate. Core studies available from 41% of the wells in the field were used …
