The Advantages of GAGD Process

 

  • GAGD process yields higher incremental oil recoveries when compared to all the currently used conventional gas injection processes (Water Alternating Gas (WAG) process recovered about 5 - 10% of the original oil in place (OOIP), while conventional Gravity Drainage field applications have yielded upto 40% OOIP and the GAGD is anticipated to do even better.
  • Comparable ultimate oil recoveries observed during field scaled laboratory GAGD experiments and gravity drainage field projects in both immiscible as well as miscible modes of operation. This would enable low pressure GAGD application, which would save significant gas compression costs.
  • Gas requirements for the GAGD process have been calculated to be substantially lower than the conventional WAG processes (2 - 3 MCF/Bbl for GAGD versus 6 - 12 MCF/Bbl). This enables even small operators to use trucked-in CO2 to produce oil from depleted oil reservoirs instead of abandoning them thereby continuing to yield profits.
  • The horizontal producer of the GAGD process has the capability of producing oil at high flow rates even at a lower drawdown. High flow rates mean quicker payback and higher profits.
  • The GAGD process is easily scalable from laboratory data to field scale though reservoir simulation. This would enable a-priori prediction of “field-scale” GAGD process performance before any investments are made.
  • In fluvial and marine stratigraphic traps, wherein the reservoir dips are significant and the placement of horizontal wells is difficult, GAGD process offers a tremendous advantage of selective drainage of structurally higher reservoir areas with horizontal wells, and later converting these ‘gassed-out’ horizontal producers into injectors. This helps drain the entire reservoir without requiring costly work-overs, infill drilling and high cost slim (horizontal) holes in the other unswept areas of the reservoir.
  • The GAGD process is applicable to both secondary as well as tertiary modes of operation in watered out and / or abandoned oil reservoirs. In tertiary mode, the mobile water production can be minimized by placing the horizontal well just above the oil-water contact, which can be inferred from detailed reservoir simulation studies.
