Comparison of Solutions to a Three-Dimensional Black-Oil Reservoir Simulation Problem (includes associated paper 9741 )

Abstract: Summary A comparison of solutions to a three-dimensional black-oil reservoir simulation problem is presented. The test of the problem and a brief description of the seven simulators used in the study are given.

Vapor-phase alkylation in presence of crystalline aluminosilicate catalyst with separate transalkylation

Abstract: A PROCESS IS PROVIDED FOR ALKYLATION OF AROMATIC HYDROCARBONS BY CONTACTING SAME WITH AN ALKYLATING AGENT IN A REACTION ZONE MAINTAINED UNDER CONDITIONS SUCH THAT SAID ALKYLATION IS ACCOMPLISHED IN THE VAPOR-PHASE AND IN THE PRESENCE OF A CATALYST COMPRISING A CRYSTALLINE ALUMINOSILICATE ZEOLITE CHARACTERIZED BY A UNIQUE X-RAY DIFFRACTION PATTERN, SAID CATALYST UNDER SAID CONDITIONS BEING CAPABLE OF AFFORDING A HIGH AND SELECTIVE YIELD OF DESIRED ALKYLAROMATIC PRODUCT. SAID ALKYLATION PROCESS IS ACCOMPANIED BY A SYSTEM FOR TRANSALKYLATION OF THE POLYALKYLAROMATIC PORTION OF THE EFFLUENT FROM SAID ALKYLATION PROCESS. THERE IS ALSO PROVIDED, WHEN SAID REACTION ZONE IS COMPRISED OF A SERIES OF REACTOR STAGES, A QUENCH FOR EFFLUENT FROM SAID STAGES BETWEEN SAID STAGES. ALSO, A CATALYST STEAM REGENERATION METHOD IS PROVIDED.

Seismic Attributes Revisited

Abstract: Since their introduction in early 1970`s seismic attributes have become one of the most commonly used and powerful interpretation tools. In earlier applications they were considered as a management display tool. This view has changed rapidly as their use in interpretation expanded. Results were analyzed in a qualitative manner. Recently, as evidenced from increasing number of papers, attribute use finally became more quantitative through calibration with well bore measurements. In this paper the authors will present a review of basic attributes, their recently introduced derivatives and their expected significance. They will also classify them with respect to their computation and their end use. They define all seismically driven parameters as the Seismic Attributes. They can be velocity, amplitude, rate of change of any of them with respect to time or space and so on. They can be computed from pre-stack or post stack data sets. Some of the attributes computed from complex traces such as envelope, phase and etc. correspond to the various measurements of the propagating wave-front. They will call those the physical Attributes. These attributes may be used for prediction or extrapolation of lithological or reservoir characteristics. Others are computed from the reflection configurations and continuity. They willmore » call these Geometric Attributes. These are used in structural and stratigraphic interpretation. In this paper they will confine themselves to the classification and definition of the attributes and their possible uses. They will give examples from different geological settings.« less

Modified crystalline aluminosilicate zeolite catalyst and its use in the production of lubes of high viscosity index

Abstract: The catalytic activity of a crystalline aluminosilicate zeolite having a Constraint Index of from about 1 to about 12 for a variety of hydrocarbon conversions including the oligomerization of olefins to provide high viscosity index lubes is significantly enhanced by modifying the catalyst to reduce surface acid sites. This is accomplished by contacting the zeolite with a fluorosilicate salt to extract surface zeolitic aluminum which is replaced by silicon.
