Abstract
A horizontal well completion apparatus and method for heavy, viscous oil in a producing zone (114) are disclosed using a single well. Hot injection fluid is injected into an injection string (120), and emitted through steam distribution holes (133) in the lower portion (120) of the injection string into the casing (116) near perforations (118). A packer (126) separates the upper well annulus (140) from the lower well annulus (142). Insulation (121) surrounds injection tubing string (120) between the packer (126) and the well head (111).
Perforations (118) in the horizontal portion (112) of the well allow heated oil to flow into the lower annulus 42 in the horizontal portion (112) of the well where is picked up by the injected fluid and lifted to the surface of the well by a jet pump (128). Temperature and pressure in the lower well annulus (142) are controlled by the temperature and pressure of the injection fluid, and the pumping rate of the produced fluids.
