Pleito Creek (San Joaquin Basin, California)
A novel (Patent-Pending) top-down combustion project is that currently operated by Nimin Energy Corp. in California.
Nimin's Combined Miscible Process (CMD) uses foamed oxygen injection into the top of a heavy oil reservoir to generate CO2, heat and steam (Figure 2). The benefits of a CO2 flood, gravity drainage and steam injection are combined together to enhance oil projection.
CMD is expected to recover 35%-61% of the OOIP.
