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

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.

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). 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.

Therefore, Oil Production = 10,000 bbl/day (Barrels/day) SOR = 3.0 Steam Required = 3 x 10,000 = 30,000 bbl/d (~4770 m3/d) How much water (condensed steam) is back? Again depends upon how much reservoir kept. Overall approach for calculating oil flow rate From Richard Chan’s thesis: The oil rate equation, Equation 2.1.18, describes vertical growth of the steam chamber corresponds to early time when steam injection has begun and the chamber is beginning to develop but has not yet reached the top of the reservoir. 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).
