Testing was initiated in 1985 with a more continuous program starting in 1989. The application of CO2 Huff 'N' Puff has increased oil production 180,000 bbls above the primary recovery with the use of 210 MMCF (12,200 tons). The CO2 treatments have been relatively small with 390 treatments performed on 240 wells.IntroductionThe Huff 'n' Puff or Cyclic W2 Process is a type of production well stimulation which involves a) injecting CO2 (either as a gas or a liquid) into a well, b) shutting in the well to allow the CO2 to dissipate and dissolve, and c) producing the well back. While each phase of the process is unique, each phase inter-relates mechanically as well as in the reservoir. Field results, reservoir analysis, and computer simulation and matching, indicate that the primary recovery mechanisms in this immiscible CO2 application appear to be 1) a shift in the CO2 saturated water/oil relative permeability, and 2) the forming of a trapped gas saturation, namely within the water phase, which results in a strong decrease of water relative permeability end point.P. 505^ Keywords: economic limit, miller, bardon, puff field case, enhanced recovery, steam-assisted gravity drainage, total recovery efficiency, society of petroleum engineers, treatment size, information Subjects: Improved and Enhanced Recovery, Thermal methods This content is only available via PDF. 1994.
