Abstract:
The production of hydrocarbons from a subterranean hydrocarbonbearing formation is stimulated by injecting into the formation an aqueous solution of a compound hereinafter described. The elimination of plugging of capillary openings within the formation and mineral scale deposition on production equipment due to post-precipitation of dissolved salts subsequent to treatment by means of said compound results in a substantial improvement in hydrocarbon recovery.
Abstract:
Lube oils of improved viscosity index are prepared by hydrocracking a heavy oil charge stock, separating the lube oil portion of the product into a light cut and a heavy cut, extracting aromatics from the heavy cut, combining the extracted aromatics with the light cut and hydrogenating the mixture. The products may be used separately or the hydrogenated mixture may be combined with the extracted heavy cut.
Abstract:
A method for decreasing the amplitude and period of bubble pulses following a primary seismic energy pulse comprises deflecting all of the expanding gases into the same direction to form the bubble into an elongated shape, and two deflector mechanisms for carrying out this method. A second method comprises generating an expanding air bubble around a body and preventing the air bubble from contracting into the body for attenuating the sudden contraction and collapse of the air bubble, and two valve devices on a closed cylinder for carrying out the latter method resulting in decreased amplitude and period of bubble oscillation for providing a clear, well-defined acoustical wave.
Abstract:
A system to facilitate connection of a tanker or similar floating vessel to a single point mooring embodying loading and offloading facilities. The mooring includes a connecting hawser capable of restraining the vessel, and to which one or more fluid carrying conduits are attached. The hawser remote end is provided with a messenger line which is maintained in a substantially upright position above the water''s surface. A catch mechanism depending from the vessel is thereby able, while moving through the water, to engage the messenger line preliminary to retrieving the hawser and fastening the vessel to the mooring.
Abstract:
A liquid phase alkylation process for production of alkylate useful as motor fuel, wherein low molecular weight isoparaffin hydrocarbons are alkylated with olefin hydrocarbons in the presence of a catalyst comprising HFSO3 and H2SO4 in weight ratio of from about 0.11 to 1 to about 0.32 to 1, respectively, having a titratable acidity in the range of 16.5 to 21 milliequivalents per gram, and which may contain about 0-3 weight percent water and about 0-10 weight percent acid oils.

Abstract:
The production of hydrocarbons from a subterranean hydrocarbonbearing formation containing acid-soluble components, such as one composed at least in part of dolomite or limestone, is stimulated by injecting into the formation a composition comprising an aqueous solution of a mineral acid having dissolved therein a compound hereinafter described. The elimination of plugging of capillary openings within the formation and mineral scale deposition on production equipment due to post-precipitation of dissolved salts subsequent to acidization by means of the said compound results in a substantial improvement in hydrocarbon recovery.
Abstract:
Significant improvement in the recovery of hydrocarbons from a subterranean hydrocarbon-bearing formation containing acidsoluble components is accomplished by injecting into the formation via an injection well drilled into a formation communicating with an adjacent producing well and containing acid-soluble components which may or may not have water-sensitive clays and shales included therein, an aqueous acidic solution of a compound hereinafter described whereupon the acid component reacts with the acid-soluble components of the formation creating passageways or enlarging existing passageways thus facilitating the flow of fluids therein and the compound prevents postprecipitation of dissolved salts and thereby increases the recovery of hydrocarbons from the formation through the adjacent producing well.
Abstract:
An automatically operating fuel dispensing nozzle adapted to function within a sealed fuel system. In particular a signal system incorporated within said nozzle which functions to permit a topping-off operation for filling a fuel tank, or for automatically discontinuing a filling operation in response to an excessive pressure which might build up within the fuel tank or other parts of the closed system.
Abstract:
Compounds of Group I alkali metals i.e., Na, K, Li, or mixtures thereof are added to the feed to the reaction zone of a partial oxidation synthesis gas generator in order to raise the level of said alkali metals to a value in the range of about 350 to 13,000 parts per million (basis weight of hydrocarbonaceous fuel feed), or more. By this means, the partial oxidation reaction may be improved. Soot formation is reduced or oxygen consumption is decreased, or both. Further, the subject process may be useful for the recovery of naturally-occurring metal values that may be present in the hydrocarbonaceous fuel feed. Thus heavy metal compounds of Ni, V, and Fe in the hydrocarbonaceous fuel may be fluxed with said alkali metals in the reaction zone of the gas generator to facilitate their separation from the process gas stream, and to extend the life of the refractory lining of the reaction zone.
