  • Patent number: 10871424
    Abstract: The invention provides a sampling apparatus for sampling fluid from a pipeline system during a pigging operation and a method of use. The sampling apparatus comprises an inlet configured to be coupled to the pipeline system, for receiving a fluid carried by a pigging operation from the pipeline system, and an outlet for discharging fluid from the sampling apparatus. A flow control valve is disposed between the inlet and the outlet. A first flow line is in communication with a sampling circuit and is disposed between the inlet and the flow control valve. A second flow line is in communication with a sampling circuit, and is disposed between the outlet and the flow control valve. The flow control valve is operable to be partially closed to create a pressure differential between the first and second flow lines, and drive a fluid passing through the sampling apparatus into the sampling circuit.

  • Patent number: 10184906
    Abstract: Predicting and quantifying free silicon in a geological formation generates free silicon data for a physical sample obtained from within the geological formation. The free silicon data include identification of portions of the physical sample containing free silicon and a quantification of the free silicon contained in the portions of the physical sample containing free silicon. A modified petro-elastic model for the geological formation comprising rock constituents is generated that incorporates free silicon as one of the rock constituents and that quantitatively models how free silicon changes elastic properties within the geological formation. A three-dimensional model of the geological formation is created that indicates volumes of free silicon throughout the geological formation. The three-dimensional model is created using geophysical data obtained from the physical sample, seismic data covering the geological formation and the modified petro-elastic model.

  • Patent number: 9291690
    Abstract: Molecular structures of organic molecules in a geological formation are determined. The organic molecules may include kerogen, coal, and/or other organic molecules. In particular, the technique implemented may operate to convert nuclear magnetic resonance data into a multi-dimensional space that permits identification of molecular structures through comparisons of intensity information across the multi-dimensional space with a cutoff map of the space. This may not only simplify the identification of molecular structures of the organic molecules, but also use exact mathematical model for mixture samples to derive both structural and dynamic parameters plus their variation.

  • Publication number: 20140377872
    Abstract: The invention is a method of predicting the amount and the composition of fluids produced by mineral reactions operating within a sedimentary basin and trapped with hydrocarbons in reservoirs. Geological data characteristic of the basin are acquired and a representation of the basin by a grid is constructed. The evolution of a depth of burial (z), a temperature (T), a pore pressure (P), a volume (V) and a porosity ? at successive ages (ti) representative of the geological history of the basin is then calculated for at least one set of cells of the grid, using a basin model and the geological data. A mineralogical or chemical rock composition is determined in each cell of the set of cells from the geological data of the basin. The amount and the composition of fluids of mineral origin is determined within the set of cells using a geochemical model and an equation of state, from the parameters, the composition and a thermodynamic database.

  • Patent number: 7718434
    Abstract: The diffusion coefficients and relaxation times of mixtures of alkanes follow simple scaling laws based on the chain length of the constituents and the mean chain length of the mixture. These scaling laws are used to determine chain sizes in a mixture from the distribution of the diffusion coefficients. These scaling laws can be used to determine the mean chain lengths (or chain lengths) of a sample (alkanes or mixtures of alkanes) and therefore the constituents of the sample.

  • Publication number: 20090087912
    Abstract: A tagged object includes a main body and a plurality of coded particles. Each coded particle may have a miniature body and be configured to provide a resolvable optical emission pattern when illuminate. The plurality of coded particles may be immobilized to the main body. A method for performing oilfield monitoring may include disposing of different types of tagged objects at different locations, wherein the different types of tagged objects each comprise a plurality of coded particles. Each of the coded particles may have a miniature body containing rare earth elements configured to produce a unique optical emission pattern when illuminated. The method may include allowing an event to trigger the release of one of the different types of tagged objects from one of the different locations. In addition, the method may include identifying the released tagged objects by unique optical emission patterns, in some cases in order to determining an occurrence location of the event.

  • Patent number: 7435597
    Abstract: The present invention is directed to novel assays for zero-valent transition metals. The novel assays of the present invention are generally methods or processes for quantitatively and/or qualitatively evaluating the presence of zero-valent transition metals on and/or within samples. Such assays generally involve a digestion process whereby the sample is exposed to carbon monoxide. Transition metals, if present in or on the sample and if contacted by the carbon monoxide, are extracted by the carbon monoxide as metal carbonyl species, the presence of which confirms the presence of transition metals. Such novel assays have enormous predictive power in oil and gas exploration.

  • Patent number: 7393689
    Abstract: The present invention provides a method and apparatus or system for determining an amount of coal tar that can enter, and subsequently be displaced from, a given type of soil for a range of depths of the soil. The method and apparatus also provide verification of the pressure at which coal tar can be displaced from a given type of soil. In particular, the method and apparatus simulate the hydrostatic pressure that a soil sample encounters in the subsurface of the ground. Accordingly, the method and apparatus provide a relationship between the concentration of coal tar in the soil and the pressure required to displace the coal tar from the soil, which allows for an estimation of the amount of coal tar that may be displaced at a particular location or site. Further, the method and apparatus are adaptable for use in the laboratory or the field.

  • Patent number: 7344889
    Abstract: A method of predicting the composition of hydrocarbon products of a complex carbonaceous material when exposed to specific time and temperature conditions is disclosed. In one embodiment, the material is characterized to obtain elemental, chemical and structural parameters. A representative chemical structure of the material is constructed based on the characterization information. The representative chemical structure is then stochastically expanded to a molecular ensemble chemical structural model that includes heteroatoms. The chemical structural model is coupled to a compositional yield model and the composition of the material products is determined using kinetic modeling.

  • Patent number: 7223602
    Abstract: The invention provides a method of online and on-site tracer generation for tagging natural gas stored in underground storage fields wherein feedstock is drawn from a feedstock source. The feedstock undergoes initial analysis to determine hydrocarbon levels. The feedstock then undergoes reaction to produce tracers such as ethylene, propylene, acetylene hydrogen and carbon monoxide. The feedstock is then analyzed to determine post reaction tracer concentration. The feedstock including generated tracers is then introduced back into the feedstock stream. Tracer levels in the pre-reaction or initial analysis of feedstock are compared with tracer levels in the post-reaction feedstock and the rate of flow of feedstock through the system is adjusted to achieve a predetermined level of tracer concentration. The level of tracer concentration will then be used to identify the particular natural gas charge in a storage field.
