Conversion of propylene and butylene over ZSM-5 catalyst

Abstract: Using the zeolite ZSM-5, new technology has been developed for catalytically oligomerizing light olefins (C3 to C4) to gasoline (C5 to C10) and diesel (C10 to C20) range product. This reaction produces product constrained by both the shape selectivity of the zeolite catalyst and the thermodynamics governing the oligomerization reaction.

Combining Outcrop Data and Three-Dimensional Structural Models to Characterize Fractured Reservoirs: An Example from Wyoming

Abstract: Combining a detailed outcrop characterization of fracture and fault occurrence with attributes from a three-dimensional model of an anticlinally folded clastic reservoir body, we determine which characteristics of the structural form and evolution are most closely related to the development of important reservoir-scale structures. Our example reservoir body studied is the Frontier Formation 1 sandstone in Oil Mountain, an asymmetric anticline on the western flank of Casper arch in central Wyoming. The three-dimensional model of the structure was constructed using an iterative scheme designed to maximize interpretation accuracy and precision. The model was analyzed to determine the spatial variance in morphologic and kinematic attributes. Using a quantitative testing approach, we found that the intensity of tectonically produced fractures is closely related spatially to rate of dip change and total curvature, with the former having the strongest correlation. This folding is a low-strain process compared to tear faulting, which has the strongest spatial correlation to larger strains. The location and magnitude of these higher strain areas can be adequately predicted by three-dimensional restoration and forward modeling of the upper bounding surface of the reservoir body. We use these results to build a predictive model for fault and fracture distribution at Oil Mountain and to discuss how this approach can aid in the exploitation of analogous producing reservoirs.

Oil recovery by enhanced imbitition in low permeability reservoirs

Abstract: A method for enhanced oil recovery from a low permeability diatomaceous reservoir by imbibition is described. In this method, oil is displaced from a single injection well, or series of injection wells into a single producer or series of producing wells by a combination of applied fluid pressure, plus "enhanced imbibition." Enhanced imbibition is accomplished by adding chemical additives to the injection fluid so that rock in the tight reservoir has a stronger affinity for the water present therein, thus releasing oil from the rock.

Process and a catalyst for preventing reactor fouling

Abstract: A support containing methylalumoxane and derivatives thereof is described which is formed by an incipient impregnation technique. The most preferred support is silica. Incipient impregnation in accordance with the invention provides a supported alumoxane, methylalumoxane, which substantially eliminates the problem of fluidized bed reactor fouling when methylalumoxane is introduced into the reactor during its operation. In accordance with the invention, the process comprises providing methylalumoxane activated metallocene compound in particulate form as catalysts in fluidized bed gas phase operation.
