Description

The objective of the project is to conduct laboratory tests to: (1) develop a method for determining MMP through direct observation using a high pressure cell; (2) determine feasibility of in-situ foam generation by visual observation and microphotographic technique. The project is presently organized and carried out in three major fronts: (1) MMP test; (2) high pressure sampling and chemical analysis; and (3) foam study and displacement test. The technical progress in each of these areas is discussed. The effects of temperature on MMP and appearance of CO/sub 2/-rich phase for four crude oils tested are plotted. The MMP is … continued below

Description

The objective of the project is to conduct laboratory tests to: (1) develop a method for determining MMP through direct observation using a high pressure cell; (2) determine feasibility of in-situ foam generation by visual observation and microphotographic technique. The project is presently organized and carried out in three major fronts: (1) MMP test; (2) high pressure sampling and chemical analysis; and (3) foam study and displacement test. The technical progress in each of these areas is discussed. The effects of temperature on MMP and appearance of CO/sub 2/-rich phase for four crude oils tested are plotted. The MMP is the pressure at which the CO/sub 2/-rich phase becomes miscible with CO/sub 2/ vapor. The results of gas chromatographic analysis for the four crude oils tested are presented. As previously stated the richness of C/sub 5/ to C/sub 20/ components is the key factor for determining the quality and stability of the miscible transition zone. The surfactant/CO/sub 2/ ratio relative to foam quality and foam quantity are presented in a table and also plotted. The plotted figures show: (1) the foam qualities increased as the surfactant rates are decreased; (2) at 75/sup 0/F, the foam quality increases as the pressure is decreased whereas the reverse is true for temperature at 120/sup 0/F; (3) foam generating rate increased with increasing surfactant/CO/sub 2/ ratio; (4) high temperatures tend to lower the rate and high pressures tend to increase the rate at 120/sup 0/F but to decrease at 75/sup 0/F; (5) foam quality was found to be affected more by surfactant/CO/sub 2/ ratio, and to a lesser degree by pressure and temperature.
