Steam oil ratio calculation
Using the Steam Property Calculator, properties are determined using Steam Pressure and Quality = 0 (Saturated Liquid). The Specific Enthalpy is then multiplied by the Mass Flow to get the Energy Flow: Steam helps to make the conditions favorable for pushing the oil toward the producing well by reducing its viscosity, which improves its mobility ratio (M) and, therefore, its displacement and areal sweep efficiency (Hong, 1994). In steam flooding, the injected steam not only lowers the oil viscosity, but also supplies the drive energy. steam production rate is reduced, then maintenance costs should more properly be considered to be variable. The second step is to calculate the cost of steam at lower pressure levels. This is not easy, as the cost depends upon the path that the steam follows from the point of generation to the point of use. In non-flow type applications the process fluid is kept as a single batch within a tank or vessel. A steam coil or a steam jacket heats the fluid from a low to a high temperature. The mean rate of heat transfer for such applications can be expressed as: q = m c p dT / t (2) where. q = mean heat transfer rate (kW (kJ/s)) The data will come for 1kg/sec. Then find enthalpy for 5/18 kg/sec. So you get enthalpy for 1 tph.every coal has GCV that is gross calorific value.For every grade there is different GCV. As efficiency of furnace is 85–90% that means ratio of heat consumed to form steam by heat given by coal is 0.85–0.90.

First, a predetermined amount of steam is injected into the well to heat the oil in the surrounding reservoir (injection stage). Once the desired amount of steam is injected, the well is shut down to allow the steam to heat reservoir around the well (soaking stage). Abstract This paper presents a simple yet sophisticated analytical model to predict cumulative steam oil ratio (CSOR) using the material/energy balance and gravity drainage theory, in which CSOR is a function of average reservoir properties (porosity, permeability, heat capacity, and thermal conductivity), and time-dependent variables (injection temperature, rising chamber height, chamber oil A limited number of laboratory and field evidences showed that steam-solvent coinjection can lead to a higher oil production rate, higher ultimate oil recovery, and lower steam-oil ratio, compared Using the Steam Property Calculator, properties are determined using Steam Pressure and Quality = 0 (Saturated Liquid).

The steam:oil ratio tells you how many barrels of steam are injected, on average, per barrel of oil produced. You will generally see two calculations – the cumulative (i.e. average over the life of the project) and the recent (usually a trailing 3-month average) steam:oil ratio provided by producers. 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
