摘要： The invention is directed to long lasting crosslinked water-soluble swellable polymers, methods for making same, and their uses. More particularly, the invention relates to a composition comprising expandable polymeric particles having cationic sites as well as labile crosslinkers and stable crosslinkers, said particle mixed with a fluid. A particularly important use is as an injection fluid in petroleum production, where the expandable polymeric particles are injected into a target zones in the reservoirs and when the heat and/or a suitable pH in the reservoir cause degradation of the labile crosslinker and when the particle expands, the cationic sites in the polymer adsorb to negative sites of the rock in the formation, thus diverting water to lower permeability regions and improving oil recovery. However, many other uses are possible.

摘要： A steam generator for burning a normally-solid fuel which produces non-combustible solid residues, including, an elongated combustion chamber, a fuel introduction means to introduce fuel adjacent the axis of the combustion chamber as a centrally-disposed stream moving in a downstream direction, a combustion-supporting gas introduction means for introducing the gas as an annular, rotating stream about the fuel stream and which, together with the fuel introduction means forms a rotating, toroidal vortex of the fuel and the combustion-supporting gas moving in a downstream direction. The combustion chamber has a volume sufficient to burn all of the fuel and, together with the fuel introduction means and the combustion-supporting gas introduction means, cause the vortex to collapse and form plug flow thereafter. Water introduction means introduces water into the flue gas at the downstream end of the combustion chamber as a plurality of peripherally-arranged jets. Preferably the water is introduced from the vena contracta of a nozzle-type orifice. A vaporization chamber, coupled to the combustion chamber, has a volume sufficient to vaporize a major portion of the water to steam and a separator separates solid residues from the flue gas-steam mixture.

摘要： The quantity of oil which can be economically recovered from an already waterflooded predominantly oil-wet formation is increased by passing a first solution through the formation to change the formation from its oil-wet to a water-wet state, passing a second solution having high interfacial tension with the oil through the formation to force the oil from the small pores of the formation into larger ones, and passing a third solution having a low interfacial tension between the third solution and the oil through the formation, optionally passing a mobility buffer-solution through the formation to prevent fingering or channeling, and finally passing the driving fluid through the formation.

摘要： A non-rigid carrier conveys a pump and/or the steam generator through a bore of the production tubing string to support enhanced oil recovery operations. An annular space separates the production tubing string and a wall of a wellbore intersecting a hydrocarbon-bearing subterranean formation. Using the non-rigid carrier, the steam generator is conveyed into the wellbore and operated to inject hot gases into the formation through the perforations in the casing. Afterwards, the steam generator is conveyed out of the cased wellbore and the pump is conveyed into the cased wellbore and operated to pump hydrocarbons to the surface. For cyclic injection operations, the pump may be retrieved to the surface and the steam generator may be returned into the well. The production tubing string, such as a production tubing, remains in the well while the pump and/or the steam generator are conveyed up and down the cased well. A base installed in the cased well receives either the pump or the steam generator.
