Instantaneous steam oil ratio

The steam to oil ratio is a measure of the water and energy consumption related to oil production in cyclic steam stimulation and steam assisted gravity drainage oil production. SOR is the ratio of unit of steam required to produce unit of Oil. The typical values are three to eight and two to five respectively. This means two to eight barrels of water converted into steam is used to produce one barrel of oil. References. Glossary at Schlumberger As in the case of any other thermal method, the first mechanism is viscosity reduction due to increase of temperature; the second mechanism is a physical displacement of oil by steam and hot water. The recovery factors for the steamflood operations are usually higher than one for the CSI and are in the range of 40-60%.

Evaporation ratio = quantity of steam generation/quantity of fuel consumed.For example quantity of steam Is 310 ton/hr and fuel is 55 ton/hr then the evaporation ratio is 5.63. Evaporation ratio is also known as steam fuel ratio.A drop in evaporation ratio indicates drop in boiler must be treated to be usable as gasoline and diesel and other useful fuels [3]. Figure 1-2 Composition of oil sands [3]. A typical oil-rich oil sand contains 80-85 mass percent sand and other minerals, 5-10 mass. percent water, and 1-18 mass percent crude bitumen [4]. The water-/oil-mobility ratio is a key parameter in determining the efficiency of the water/oil displacement process, with the recovery efficiency increasing as the water-/oil-mobility ratio decreases.

Steam Assisted Gravity Drainage (SAGD) is widely used in the Athabasca oil Here, the observed variable is the instantaneous Steam-to-Oil Ratio (iSOR) with 

At 75 months, the M-V displacement was 132% of original oil in place, while the Jones model corrected it to 91%. This calculation was done to an unrealistic terminal point, but if the flood were terminated at 48 months when instantaneous oil/steam ratio had fallen to below 0.2 then recovery calculated by Jones would be 77%. Definition of steam-oil ratio: 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. Steam to Oil Ratio Optimization using Analytics & Machine Learning is built on proven technology, implemented by IBM Clients across industries, and supported by IBM’s math department – the largest in the world.

SOR abbreviation stands for Steam to Oil Ratio. What is the abbreviation for Steam-Oil Ratio? What does SOR stand for? SOR abbreviation stands for Steam-Oil Ratio. Water-Oil Ratio Forecasting Theory. Water-oil ratio (WOR) forecasting is a method of trending future water production for the purpose of forecasting oil production and determining expected ultimate recoverables (EUR). Water-oil ratio forecasting is an empirical analysis method; there is no formal model or equations.

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. In this technique the Steam to Oil Ratio is three to eight (3-8). This simply means that three to eight barrels of water are converted into steam which produces one barrel of crude oil. Commonly abbreviated as SOR, it measures the volume of steam required to produce one unit volume of oil. Typical values of SOR for cyclic steam stimulation are in the range of three to eight, while typical SOR values for steam assisted gravity drainage are in the range of two to five. The SOR used here is not a cumulative steam-to-oil ratio but instantaneous steam-to-oil ratio used to estimate oil production from reservoir. The SAGD model used in this work is applicable only for the ramp-up stage (i.e., the reservoir has not reached the cap rock). Reducing Steam Oil Ratio in Steam-Assisted Gravity Drainage (SAGD) Abstract. North America's long-term energy future depends heavily upon the Athabasca oilsands. Only 15% of these deposits are at mineable depths (<90m) and thus 85% of the oilsands (232 billion bbl recoverable reserves) must be recovered using in-situ techniques.

SOR is the ratio of unit of steam required to produce unit of Oil. The typical values are three to eight and two to five respectively. This means two to eight barrels of

A simplified model estimates oil production rates for mature steamfloods. The mechanisms included are gravity drainage and viscous flow of the oil induced by flowing steam. Three examples of vertical wells are presented. The oil/steam ratio is also illustrated, as well as the pressure drop in the steam phase. The steam to oil ratio is a measure of the water and energy consumption related to oil production in cyclic steam stimulation and steam assisted gravity drainage oil production.

The recovery factors for the steamflood operations are usually higher than one for the CSI and are in the range of 40-60%. Since the air-fuel stoichiometric ratio is 14.4 pounds of air per pound of fuel, the boiler's burner would need 20 gallons x 7.95 lb/gal for No. 6 fuel oil, or 2,289 pounds of air to burn the oil. This would in turn yield a total flow of 2,628.1 lb/hr of steam. Water-Oil Ratio Forecasting Theory.
