In-situ gasification of tar sands utilizing a combustible gas

Abstract: A subterranean, viscous oil-containing formation, e.g. tar sands, which has previously been exploited by an in-situ combustion operation to recover the maximum amount of oil therefrom and leaving a solid coke like residue in the formation, is first saturated with a combustible gas such as methane, ethane, propane, natural gas or mixtures thereof, thereafter reinitiating in-situ combustion and then injecting a mixture of an oxygen-containing gas and steam to convert the coke like residue to a combustible product gas consisting predominantly of carbon monoxide and hydrogen within the formation. The combustible product gas is recovered and may be utilized directly as a fuel gas, or may be utilized as feed stock for petro chemical manufacturing processes.

Method for producing low permeability reservoirs using steam

Abstract: A method for recovering hydrocarbons (e.g. oil) from a low permeability subterranean reservoir of the type comprised primarily of diatomite. A first slug or volume of a heated fluid (e.g. 60% quality steam) is injected into the reservoir at a pressure greater than the fracturing pressure of the reservoir. The well is then shut in and the reservoir is allowed to soak for a prescribed period (e.g. 10 days or more) to allow the oil to displaced by the steam into the fractures by imbibition. The well is then produced until the production rate drops below an economical level. A second slug of steam is then injected and the cycles are repeated with the volume of each subsequent slug of steam being progressively smaller that the one before it (i.e. about 80%) and the respective soak period being increased by about 20% over that of the previous cycle.

Process for manufacturing olefinic oligomers having lubricating properties

Abstract: A process for oligomerizing alpha olefin to produce lubricant range hydrocarbon stock including the step of contacting said alpha olefin with a supported solid reduced Group VIB (e.g., chromium) catalyst under oligomerization conditions at a temperature of about 90° to 250° C. to produce liquid lubricant hydrocarbon. The product comprises the polymeric residue of linear C 6 -C 20 1-alkenes, said composition having a branch ratio of less than 0.19. The weight average molecular weight is between 420 and 45,000, number average molecular weight between 420 and 18,000, molecular weight distribution between 1 and 5 and pour point below -15° C. The hydrogenated lubricant range hydrocarbon product has viscosity index of about 130 to 280 and viscosity up to about 750 cS. The process is particularly useful where the starting alpha olefin consists essentially of olefinic hydrocarbon having 8 to 14 carbon atoms or mixtures thereof; wherein the process conditions include reaction temperature of about 100° to 180°; and wherein the support catalyst includes porous inert silica.
