Abstract: Multi-metallic bulk catalysts and methods for synthesizing the same are provided. The multi-metallic bulk catalysts contain nickel, molybdenum tungsten, niobium, and optionally, titanium and/or copper. The catalysts are useful for hydroprocessing, particularly hydrodesulfurization and hydrodenitrogenation, of hydrocarbon feedstocks.

Abstract: A method is disclosed making a molecular of TON framework type having unique properties. The method uses 1,3,4-trimethylimidazolium cations as a structure directing agent and a combined source of silicon and aluminum selected from alumina-coated silica and aluminosilicate zeolites. The obtained molecular sieve can be used in processes for dewaxing paraffinic hydrocarbon feedstocks.

Abstract: A method is described for property estimation including receiving a seismic dataset representative of a subsurface volume of interest and a well log from a well location within the subsurface volume of interest; identifying seismic traces in the seismic dataset that correspond to the well location to obtain a subset of seismic traces; windowing the subset of seismic traces and the well log to generate windowed seismic traces and a windowed well log; multiplying the windowed seismic traces and the windowed well log by a random matrix to generate a plurality of training datasets; and training a neural network using the plurality of training datasets. The method may be executed by a computer system.

Abstract: A method is described for data analytics using highly-correlated features which includes receiving a training dataset representative of a subsurface volume of interest; identifying at least two highly-correlated features in the training dataset; calculating a trend of the at least two highly-correlated features; calculating a residual of at least one of the highly-correlated features and the trend; and using data analytic methods on features in the training dataset that include one or more of these trend and residual combinations to predict a response variable. The method may be executed by a computer system.

Abstract: An improved reforming process for producing aromatic hydrocarbons is disclosed. The process includes two reformers arranged in parallel flow configuration, with the first reformer being a conventional reformer comprising a catalyst selective for reforming C8+ hydrocarbons to a reformate and the second reformer comprising a catalyst selective for reforming C7− hydrocarbons to a reformate. In certain embodiments, the first reformer catalyst comprises a conventional alumina catalyst and the second reformer catalyst comprises a ZSM-5 catalyst.

Abstract: Disclosed are compositions and methods for the pressure protection of existing wells during infill drilling operations. The methods can include injecting a foamed pressure protection composition into the existing wellbore in fluid communication with an unconventional subterranean formation prior to and/or during fracturing of the new wellbore in fluid communication with the unconventional subterranean formation.

Abstract: Provided in one embodiment is an improved and more flexible process for preparing a finished base oil or a white oil product comprising passing a dewaxed base oil product to a distillation column and separating the dewaxed base oil product into fuel and base oil product streams. The base oil product streams are tested to determine if they meet desired specifications. Base oil product streams that meet the desired minimum base oil specifications are passed to a hydrofinishing reactor to prepare a white oil product, or passed to direct sale.
