Definitions

  • the present invention relates to an unparalleled method of recovery of underground crude oil, from very light to very heavy as well as tar sands, in a novel method yet unaccomplished in oil industry by introduction of a combination of some brand new features in the recovery technology.
  • the brand new features are a simple draining concept right from primary recovery stage that will minimize viscous fingering and minimize cross flow effects; a significantly improved heating method that will be applicable to recovery of heavy, very heavy and tar sand oil so far not possible in commonly known thermal recovery techniques; a miscibility enhancing technique with much improved feature by incorporating only nitrogen as miscibility fluid with added chemical for miscibility enhancement i.e.
  • An additive to lower minimum miscibility pressure of nitrogen will also be required that will call for search of such chemical in laboratory.
  • One such chemical is methane gas, as a boon in disguise, in the process methodology suggested (feature 'e' below).
  • Figures 1 and 2 show the concept elaborately (annexed in the Figure section below). Basically, the isobars are parallel and less curvaceous and gradually decreasing from bottom to top in a manner yielding very high pressure gradient (because of choice of production well pressure held) and very low viscous fingering.
  • Aquifer-supported Pools In case of aquifer adjacent to pool(s), pool boundary segment that is aquifer supported must be accurately detected from reservoir engineering tool(s) such as well tests etc. Depending on dip of aquifer-pool system, and the pressure gradient existing in the aquifer and pool side(s), appropriate injection wells can be placed to enable advancing the aquifer pool contact region towards pool interior and through to the other end. From this discussion, it appears that pools with aquifer support will be better exploited with advancing of the contact right from the beginning of the primary recovery period.
