Abstract: Seismic pulses are emitted are emitted with consecutive time intervals that follow a pattern described by several Golomb rulers, wherein at least two of the Golomb rulers have at least four marks, such that pair-wise time intervals between seismic pulse emissions are different, to distinguish seismic reflections stemming from different seismic pulses and/or seismic sources from each other. This allows executing seismic surveys with several simultaneously operated seismic source arrays, thereby reducing the survey cost. In a marine environment the seismic sources may be air-gun arrays towed by one or more vessels, and the method can be also applied onshore.

Abstract: A composition having a substantial or material absence of or no phosphorous and comprising a support material, a metal compound and either a hydrocarbon oil or a polar additive or a combination of both a hydrocarbon oil and polar additive. The polar additive has particularly defined properties including having a dipole moment of at least 0.45. The composition is useful in the hydroprocessing of hydrocarbon feedstocks, and it is especially useful in the hydrotreating of vacuum gas oils and petroleum resid feedstocks.

Abstract: A method of treating a subterranean formation via well bore may include introducing a plurality of particles into the subterranean formation via the well bore, each particle having a substrate and a layer of cement on the substrate. The cement may be in a state of suspended hydration and the method may include introducing moisture to the subterranean formation via the well bore. The method may also include allowing the particles and the moisture to contact one another. Contact between the particles and the moisture may cause the cement to move from a state of suspended hydration to a state of secondary hydration.

Abstract: A process for converting one or more C3-C12 oxygenates comprising:1) contacting a feed comprising C3-C12 oxygenates with hydrogen in the presence of a sulphided hydrogenation catalyst to produce a partially hydrogenated effluent;2) contacting the partially hydrogenated effluent with hydrogen at a hydrogen partial pressure of at least 0.1 MegaPascal in the presence of a sulphided carbon-carbon coupling catalyst to produce a conversion product;3) optionally contacting at least part of the conversion product with hydrogen in the presence of a sulphided hydrotreating catalyst and/or a sulphided hydroisomerization catalyst to produce a conversion product; and4) optionally purifying the conversion product, optionally hydrotreated and/or hydroisomerized, conversion product to obtain a final product, wherein the carbon-carbon coupling catalyst comprises at least 60 wt % of a zeolite and in the range from 0.1 wt % to 10 wt % of a hydrogenation metal, based on the total weight of the carbon-carbon coupling catalyst.

Abstract: Methods for constraining basin models to forecast the presence and maturity of hydrocarbon in a basin. The method involves determining a Curie depth at a location at the basin, constraining basin models to match the Curie depth at the location and determining the presence of hydrocarbon in the basin based on the basin models constrained by Curie depth.
