Patent CA-2809088-A1 (CA)
Inventor: AMITAI GADI
IPC: C02F3/00
Filed: 2011-08-24
Abstract: The invention provides a system for treatment of wastewater. A pumping system pumps wastewater from a source basin to a recipient basin, while a conduit allows gravitational flow of water from a source basin to a recipient basin when the pumping system is inactive. A controller activates the pumping system to pump wastewater from the source basin to a recipient basin when a wastewater level in the source basin is at a first predetermined height or when a rate of gravitational flow wastewater from the source basin to the recipient basin is below a first predetermined flow rate. The controller also turns off the pumping system when the water level in the source basin is at a source basin minimal level and the water level in the recipient basin is at a recipient basin maximal level. The invention also provides a method for operating a wastewater treatment of the invention, and a pumping system for use in the system of the invention.

Abstract: The present invention is a method and apparatus for enhanced recovery of petroleum fluids from the subsurface by steam injection into highly permeable vertical inclusion planes in the oil sand formation, and heating the heavy oil and bitumen, which flow by gravity to the wells. The inclusion is propagated into a portion of the formation having a Skempton's B  parameter of greater than 0.95 exp(-0.04 p')+0.008 p', where p is a mean effective stress in MPa at the depth of the inclusion. The inclusion planes can be propagated from only the central well, or from all wells, being the central well and the periphery wells. The inclusion planes are propagated into the formation to intersect and coalesce to provide hydraulic connection between the central well and the periphery wells. Steam is injected continuously in the central well, and liquids are produced continuously from all wells, whilst maintaining a liquid head over production tubing for steam trap control. By injection of solvents and other gases and controlling the reservoir temperature and pressure, a particular fraction of the in situ hydrocarbon reserve is extracted and water inflow into the heated zone is minimized.
