In 1998, the author began researching suitable technology for compressing 95 MMSCFD of “bone dry” (–100°F dew point) carbon dioxide (CO2) from 16.7 psia to 2,710 psia. The compressed CO2 is delivered via a 205-mi pipeline to operations near Weyburn, Saskatchewan, Canada. The oil fields use the gas in enhanced oil recovery (EOR). As an added benefit to the environment, virtually all of the injected CO2 is expected to remain permanently sequestered in the depleted oil fields long after these fields are abandoned. Options Three compression options were closely considered for this project: Option 1: Motor + gear increaser + low-pressure (LP) compressor + medium-pressure (M
