Steam-oil ratio

Steam-oil ratio,

Definition of Steam-oil ratio:

  1. A metric used in oil recovery measuring the volume of steam required to generate one unit volume of oil. The metric will vary depending upon the extraction technique used. The ratio is a benchmark for evaluating process efficiency.

  2. The steam-oil ratio helps standardize guidelines for efficiency in oil recovery and production. The ratio shows how well a specific steam process works compared to others. For example, a steam-oil ratio of 4.5, indicates 4.5 barrels of water converted to steam to produce one barrel of oil. This method is more efficient than one with a ratio of 6.5 as less steam is required to recover the same amount of petroleum. Lower steam requirements indicate a lesser cost of production.

  3. The steam-oil ratio is the measurement scientists and engineers use to quantify the efficiency of enhanced oil recovery (EOR) processes which use various forms of steam injection. The ratio compares the volume of steam used to produce a barrel of crude oil. Lower ratios will indicate more efficient processes. As technology improves, less steam is required to generate a barrel of oil.
