A method is provided for efficiently characterizing rock traversed while drilling a borehole for hydrocarbon reservoir development. A rock sample can be obtained having a provenance of collection linked to a specific region of the borehole, which is scanned to obtain a 2D digital image that is segmented to pixels characterized as pore space and as mineral matrix and defining a boundary between them. A transform relationship, for example, a form of the Kozeny-Carman equation adapted for application to a 2D segmented image environment, can be applied to calculate the estimated value for a target rock property, which can be absolute permeability, relative permeability, formation factor, elasticity, bulk modulus, shear modulus, compressional velocity, shear velocity, electrical resistivity, or capillary pressure, and the estimated value is used to characterize the rock at that region of the borehole. This affords an opportunity to quickly and efficiently develop massive data directly characterizing extended regions of rock, whether traversed by the borehole in this or a related well. Computerized systems, computer readable media, and programs for performing the methods are also provided.

A catalyst is described which comprises at least one zeolite with structure type EUO, at least one zeolite selected from IM-5 zeolite and zeolites with structure type MFI, MOR, BEA and MTW, at least one group VIII metal, at least one group IIIA metal and at least one porous mineral matrix. The catalyst of the invention is used in a process for isomerizing a feed comprising aromatic compounds containing 8 carbon atoms per molecule.

A method is provided for characterizing and quantifying the pyritic sulfur and the organic sulfur separately in a sedimentary rock sample. A rock sample is subjected to a heating process in an inert atmosphere, the effluents resulting from the heating in the inert atmosphere are continuously oxidized, the released SO2 is continuously measured, and a pyrolysis sulfur content and a pyrolysis pyriticsulfur content are deduced. The residue heated in the inert atmosphere is heated in an oxidizing atmosphere, the released SO2 is continuously measured, and at least oxidation sulfur content is deduced therefrom. The pyritic sulfur content is determined from the pyritic pyrolysis sulfur content and a weighting function taking account of a first parameter representing a thermal degradation rate ofthe pyrite, a second parameter representing the impact of the mineral matrix, and a third parameter representing the impact of the organic matrix. In addition, the organic sulfur content can be determined from at least the oxidation sulfur content, the pyrolysis sulfur content and the pyritic sulfur content. Application: in particular to oil exploration and exploitation.

A process for the production of middle distillates comprising at least one hydrocracking stage that oligomerizes a paraffinic feedstock produced by Fischer-Tropsch synthesis, the process using a catalyst that comprises at least one hydrogenating-dehydrogenating metal that is selected from the group that is formed by the metals of group VIB and group VIII of the periodic table, by themselves or in a mixture, and a substrate that comprises a beta zeolite in the form of crystallites with a mean size that is less than 100 nm dispersed in at least one porous mineral matrix, whereby the beta zeolite has a mesopore volume of less than 0.4 ml / g.
