Abstract: A method of making a cement composite can include contacting an aqueous solution comprising calcium ions with a carbon dioxide source producing a carbonated aqueous solution. Fine particles can be submerged in the carbonated aqueous solution to produce microaggregate particles comprising the fine particles coated with calcium carbonate. The microaggregate particles can be combined with cement particles to produce the cement composite. The cement composite can be used in cementing applications for hydrocarbon wells including for casing liners and well plugs.

Abstract: A process for producing renewable distillate-range hydrocarbons is provided. The process includes dehydrating a renewable C2-C6 alcohol feedstock to produce an olefin, oligomerizing the olefin the presence of a halometallate ionic liquid catalyst to produce an oligomer product and hydrogenating the oligomer product or fractions thereof to produce saturated distillate-range hydrocarbons.

Abstract: Current profile of water (e.g., ocean) around a riser connected to a wellhead may be measured and used to determine integrated current load on the riser at any given moment in time. The integrated current load may be used to estimate the wellhead fatigue damage rate at that moment in time. The estimated wellhead fatigue damage rate may be used to make operational decisions for the well.

Abstract: An improved hydrotreating catalyst and process for making a base oil product. The catalyst comprises a base extrudate of a high nanopore volume amorphous silica alumina (ASA) and alumina. The catalyst and process use a high nanopore volume ASA/alumina based catalyst to produce hydrotreated dewaxed base oil products from a hydrocarbon feedstock. The base extrudate comprises ASA having a pore volume in the 11-20 nm pore diameter range of 0.2 to 0.9 cc/g and an alumina having a pore volume in the 11-20 nm pore diameter range of 0.01 to 1.0 cc/g. The base extrudate formed has a total pore volume in the 2-50 nm pore diameter range of 0.12 to 1.80 cc/g. The catalyst further comprises at least one modifier element from Groups 6 to 10 and Group 14 of the Periodic Table. The catalyst and process provide improved aromatics saturation.

Abstract: A method for identifying shut-ins of a well may include obtaining raw pressure values captured over a period of time, where each of the raw pressure values indicates a pressure at a bottom hole of the well; applying filters to the raw pressure values to generate a plurality of filtered pressure values; identifying initial sequences having monotonically trending values among the plurality of filtered pressure values; splicing adjacent initial sequences; adjusting the start point of at least one of the initial sequences based on derivatives of the filtered pressure values; applying a parametric function to the initial sequences to generate fitted sequences; and applying a pattern recognition to the fitted sequences to generate final sequences.

Abstract: A method is described for determining well integrity including deploying seismic sensors in a wellbore; attaching a vibrational source to well hardware; using the vibrational source to generate seismic signal that moves through the wellbore; creating a seismic dataset by recording the seismic signal at the seismic sensors; and processing the seismic dataset to make a processed seismic image. The processed seismic image may be displayed on a graphical display in order to identify well integrity problems such as wellbore deformation, well casing damage, or problems with cement.
