Effect of Solvent on Steam Recovery of Heavy Oil

Abstract: Solvents and light ends of crudes are frequently used as diluents to facilitate pumping and pipeline transportation of heavy crudes. The use of solvent alone for in-situ recovery of heavy oil tends to be limited because of its high cost; however, the use of solvent as an additive to steam processes has been tested both in the laboratory and in the field. The results of these tests are mixed. In this study, the authors use numerical experiments to delineate the recovery mechanism of a steam-slug process when solvents are present. A good understanding of the mechanism will help provide an interpretation of the conditions under which solvents can improve steam oil recovery. The study focuses on the use of small quantities of solvent-i.e., no more than 10% of the steam volume.

Alkylation of aromatic compounds in the presence of an alumino-silicate catalyst

Abstract: A process for producing alkylated organic compounds comprises effecting reaction of an alkylating agent and an aromatic hydrocarbon, or aromatic hydrocarbon containing a nonpolar substituent, at a temperature not in excess of 600 DEG F., in the presence of a superactive catalyst comprising a base-exchanged crystalline aluminosilicate having a residual sodium content not greater than 6% by weight of the dry aluminosilicate and a pore size of 6 to 15 Angstrom units; said catalyst having an activity constant above 10. Cations present in the catalysts used are rare earth metals, hydrogen or mixtures thereof. Reaction preferably takes place at 100 DEG to 600 DEG F. and aromatic hydrocarbons used are benzenes, naphthalenes, phenanthrenes and anthracenes and alkylating agents used are C2-C20 olefines, alkyl halides or aliphatic alcohols containing 1 to 20 carbon atoms in the alkyl group and the molar ratio organic hydrocarbon: alkylating agent is preferably at least 3:1. The reaction is preferably carried out under sufficient pressure to maintain the organic hydrocarbon in the liquid phase and the organic hydrocarbon may be allowed to saturate the catalyst before the alkylating agent is added. The catalyst may be combined with conventional porous adsorbents, carriers and supports.ALSO:Base-exchanged crystalline aluminosilicates having a residual sodium content not greater than 6% by weight of the dry aluminosilicate, a pore size of 6 to 15 Angstrom units and a catalyst activity constant above 10 are prepared by conventional treatments involving partial replacement of sodium ions by rare earth metal ions and hydrogen ions. Zeolite X is the preferred aluminosilicate.

Traction structures in deep-marine, bottom-current-reworked sands in the Pliocene and Pleistocene, Gulf of Mexico

Abstract: The Pliocene-Pleistocene sequence cored in the Ewing Bank and Garden Banks areas in the Gulf of Mexico provides an example of deep-marine sand reworked by bottom currents. A distinctive attribute of these sands is their traction structures, which include cross-stratification, current ripples, and horizontal lamination. These sands also exhibit sharp upper contacts, inverse size grading, mud offshoots, and flaser bedding. An important aspect of these structures is their occurrence in discrete units, but not as part of a vertical sequence of structures, such as the Bouma sequence. Presumably, the Loop Current, a strong, wind-driven surface current in the Gulf of Mexico, impinged on the sea bottom, as it does today, and resulted in bottom-current-reworked sands. A depositional model is proposed in which the bottom-current-reworked sands tend to develop a facies in interchannel slope areas that is distinctly different from channel-levee turbidite facies.
