Systems and methods for hydrocarbon recovery

A method has been invented for recovering hydrocarbons from an earth formation containing hydrocarbons, the method including injecting a recovery injectant into the earth formation at a plurality of injection points spaced apart by about 14 to about 208 feet, and producing hydrocarbons from the formation with at least one producer well. In one aspect the method includes injecting steam into an earth formation which contains oil bearing diatomite at a plurality of injection points spaced apart by about 14 to about 208 feet, and producing hydrocarbons from the formation with a one or more producer wells extending into the oil bearing diatomite formation, with a plurality of producer wells spaced apart by a distance ranging between about 14 to about 149 feet, injecting steam into the oil bearing diatomite at an injection rate of between about 10 to about 149 barrels of steam per day per hundred feet thickness of diatomite, and injecting the steam at a pressure between about 10 p.s.i. to about 260 p.s.i. The present invention also discloses a method for treating a hydrocarbon-bearing diatomite formation including applying an artificial overburden over at least a portion of the formation and applying a variable well spacing as needed. A field on an earth formation has been invented for recovering hydrocarbons, the earth formation having an earth surface above it, the field including a plurality of injector well and a plurality of producing wells, the field including at least one injector well per acre of earth surface above the earth formation and at least one producing well per acre. Certain parts of the wells may be in below-grade chambers.

The invention discloses an efficient energy saving electro heating multipurpose cooker utilizing a new method of accurate temperature controlling and healthy cooking. The technical scheme of the invention is as follows: the outside surface of the cooker body is provided with an ambient temperature sensor; the base of the cooker is provided with an inner pot temperature sensor; the cooker body, thecooker cover and the cooker base are all set to be closed efficient heat insulation interlayers; the closed heat insulation interlayer on the cooker base is arranged between the casing of the cookerbase and the electro heating device; a hallow cavity is arranged between the casing of the cooker base and the closed heat insulation interlayer; and the purposes of energy saving, discharge reducingand healthy cooking can be realized by setting standard control values such as ambient temperature or temperature drop, cooking/steaming temperature and time and the like by an automatic control device and by comparing the ambient real-time temperature or temperature drop with the inner pot real-time temperature to control the power on and power off of the electro heating device. The efficient energy saving electro heating multipurpose cooker can be used for cooking rice, cooking congee, cooking soups and steaming food; compared with various electro rice/congee/soup cooker in the prior art, the invention can save electricity by 30%-50% and can be widely used in families, dining halls and catering enterprises in cities and towns.
