Abstract: Lost circulation particles are commonly used in drilling and/or cementing operations to prevent fluid loss to a subterranean formation. Drilling fluids and methods of drilling and/or cementing operations may also use petroleum coke lost circulation particles composed of fluid coke and/or flexicoke material. Such petroleum coke lost circulation particles may have improved transport into wellbores because of their lower density compared to traditional lost circulation material and may produce fewer fines that can interfere with lost circulation efficacy.

Abstract: A method for liquefying a feed gas stream. A refrigerant stream is cooled and expanded to produce an expanded, cooled refrigerant stream. Part or all of the expanded, cooled refrigerant stream is mixed with a make-up refrigerant stream in a separator, thereby condensing heavy hydrocarbon components from the make-up refrigerant stream and forming a gaseous expanded, cooled refrigerant stream. The gaseous expanded, cooled refrigerant stream passes through a heat exchanger zone to form a warm refrigerant stream. The feed gas stream is passed through the heat exchanger zone to cool at least part of the feed gas stream by indirect heat exchange with the expanded, cooled refrigerant stream, thereby forming a liquefied gas stream. The warm refrigerant stream is compressed to produce the compressed refrigerant stream.

Abstract: Proppant particulates like sand are commonly used in hydraulic fracturing operations to maintain one or more fractures in an opened state following the release of hydraulic pressure. Fracturing fluids and methods of hydraulic fracturing may also use proppant particulates composed of high-flow polyolefin coated mineral particles (referred to as high-flow polyolefin coated mineral proppant particulates). In some instances, the high-flow polyolefin-coated mineral proppant particulates have a particle density of equal to or less than about 1.35 grams per cubic centimeter, and further may be prepared using a one-pot hot melt process.

Abstract: A method for determining geologic age of hydrocarbon samples, such as oils, using novel age biomarkers may comprise: measuring a concentration or related value of triaromatic dionsteranes (TAD) in a hydrocarbon sample, migrated oil sample, from a North Atlantic conjugate margin (NAM); calculating a TAD index for the hydrocarbon sample based on the concentration or the related value of the TAD; and predicting an age of the hydrocarbon sample based on a correlation between a hydrocarbon age and the TAD index.

Abstract: Embodiments described herein provide enhanced low-density hollow glass bead (HGB) fluids, as well as methods for utilizing such HGB fluids for wellbore drilling operations, completion operations, and workover operations. Such low-density HGB fluids include the following combination of constituents: a base oil, an oil viscosifying agent, HGBs at a concentration in a range between 20 vol % and 60 vol %, an organophilic clay, a clay activator, a surfactant, and (optionally) an H2S scavenger. Moreover, the low-density HGB fluids are suitable for use as lower-density cap fluids for pressurized mudcap drilling (PMCD) operations, alternative drilling fluids for managed pressure drilling (MPD) operations, alternative drilling fluids for conventional drilling operations corresponding to very-low-pressure or highly-depleted reservoirs, and/or lightweight fluids for wellbore workover operations.

Abstract: Methods of generating a parameter realization, for a subsurface parameter, as a function of depth within a subsurface region are disclosed herein. The methods include dividing a subsurface parameter profile for the subsurface region into a plurality of adjacent stratigraphic units. The methods also include splitting each stratigraphic unit of the plurality of adjacent stratigraphic units into a plurality of stratigraphic unit layers. The methods further include determining a layer parameter value range for each stratigraphic unit layer of the plurality of stratigraphic unit layers and for each stratigraphic unit. The methods also include, within each stratigraphic unit layer, selecting a corresponding layer parameter value from within the layer parameter value range. The methods further include generating the parameter realization by assigning the corresponding layer parameter value to the parameter realization for a corresponding layer depth range of each stratigraphic unit layer.
