... by engineers worldwide. Theoretical calculations and field practice have shown that DWS can improve oil production rate, reduce water cut, and increase oil productivity index of a well. However, the technique requires draining and lifting of large amounts of water from the aquifer, which increases the cost...

.... Three pairs of SAGD operation began in April of 1997 after three months of circulation. Many interesting characteristics were identified in the injection and production history. During the first year of operation, pressure and oil production rates decreased when steam injection rates were reduced. After...

Network used was feed forward backpropagation neural network with 10 nodes in the input layer corresponding to current and nine past oil production rates, 8 neurons in the hidden layer with nonlinear Tan-Sigmoid...

... Abstract A new correlation has been developed to predict bitumen/heavy oil production rates for solvent based gravity drainage. The correlated data set includes 60 individual rate measurements with both published and previously proprietary experimental data. The data set includes 11 crude oils...

... the promising feature of warm VAPEX process in terms of enhanced oil production rates. Introduction The vapor extraction (VAPEX) process has recently drawn lots of attention for the recovery of heavy oil. The increasing trend in the energy costs along with great concerns regarding the environmental aspects...

... was studied to investigate the performance of SAS and SAGD processes in heavy oil reservoirs. Oil production rate for SAS process was higher than that of the SAGD process. The pumping schedules for the SAS process showed that the high production was achieved by injecting steam for a year and solvent for half...

... decades, it is still a challenging technical task to predict its stabilized oil production rate. It has been reported in the literature that the predicted oil production rate can differ from the measured oil production data by several factors to one order. In this paper, physical modeling is conducted...

... in an improved oil production rate. All components of naphtha travelled freely in the vapour chamber and accumulated along the vapour chamber front in both the vapour and oil phases. At higher solvent to steam ratios oil production rate decreased due to an accumulation of solvent gas at the vapour chamber front...

...) . The advantage of the SAGD process is its relatively higher oil production rate. However the higher production rate is associated with excessive energy requirements, CO 2 generation, and post-production water treatment. The Vapex process has the advantage of lower energy consumption, therefore, less CO 2...

.... Surfactant-SAGD process was shortened the lead time and enhanced oil production rate after steam breakthrough. Introduction Steam-assisted gravity drainage (SAGD) is a very promising recovery process to produce heavy oils and bitumen resources. The method ensures both a stable displacement of steam...
