... to be adequate for field scale CO-foam simulation. The results also confirm that the communication path between the foam injection well and the offending well had a strong impact on the production performance.

Paper presented at the SPE Permian Basin Oil and Gas Recovery Conference, March 23–26, 1998
Paper Number: SPE-39789-MS
... Abstract Some surfactants that we tested were found to be more capable of selectively reducing gas mobility by a greater fraction in high- permeability sands. It is expected that foam can mitigate the problem of an early gas breakthrough in EOR processes. Laboratory experiments were conducted...

Paper presented at the SPE Permian Basin Oil and Gas Recovery Conference, March 23–26, 1998
Paper Number: SPE-39792-MS
... Abstract The potential for using mixed surfactants at low concentration to improve mobility control in CO flooding was evaluated in laboratory experiments. We examined various mixed surfactant systems, such as alpha olefin sulfonate and ethoxylated alcohol sulfate, through foam durability...

Paper Number: SPE-35172-MS
... Abstract In this paper, we investigate whether foams can show placement properties that are superior to those of gels, when used as blocking agents. Specifically, we examine whether the concept of limiting capillary pressure can be exploited to form a persistent, low-mobility foam in high...

Paper Number: SPE-35168-MS
... Abstract CO 2 -foam has been long realized as an effective mobility reducing agent for CO 2 flooding in oil recovery process. Recent researches indicate that some CO 2 - foams also show an exciting additional characteristic, selective mobility reduction (SMR), in which the mobility of foam...

Paper Number: SPE-27729-MS
... Abstract Carbon dioxide flooding has been recognized as an efficient means of recovering oil. However, the efficiency is marred due to the unfavorable mobility ratio between CO2 and the oil to be displaced and the poor sweep efficiency resulting from the heterogeneity of the reservoir...
