A process for converting gaseous alkanes to olefins, higher molecular weight hydrocarbons or mixtures thereof wherein a gaseous feed containing alkanes may be thermally or catalytically reacted with a dry bromine vapor to form alkyl bromides and hydrogen bromide. Poly-brominated alkanes present in the alkyl bromides may be further reacted with methane over a suitable catalyst to form mono-brominated species. The mixture of alkyl bromides and hydrogen bromide may then be reacted over a suitable catalyst at a temperature sufficient to form olefins, higher molecular weight hydrocarbons or mixtures thereof and hydrogen bromide. Various methods and reactions are disclosed to remove the hydrogen bromide from the higher molecular weight hydrocarbons, to generate bromine from the hydrogen bromide for use in the process, to store and subsequently release bromine for use in the process, and to selectively form mono-brominated alkanes in the bromination step. One or more of the reactions of the processes of the present invention may be conducted in a microchannel reactor.

A method of determining a numerical index from a cored well that corresponds to the performance data of a portion of a reservoir and a method of extrapolating the performance of such portion of a reservoir to the entire reservoir through use of the numerical index. Selected variables which affect fluid flow in the reservoir are compared by a statistical analysis computer program to performance data of the computer simulated portion of the reservoir after both the data and variables have been normalized to dimensionless values. The resulting numerical index is computed for the cored wells both inside and outside the small reservoir area, and a contour or iso-index map is drawn. Well performance outside the simulated area can be compared to expected performance through the numerical index values.
