Lessons Learned
Early molasses injection events used realtively high concentrations of molasses (10%-18%) with relatively low volumes of molasses solution ranging from 130 to 235 gallons per injection well. The last two injection events used lower concentrations of molasses (0.2%) but higher injection volumes (3,600-7,786 gallons per well) in an attempt to achieve a greater radius of influence. |
