| 20080282790 | Method and Apparatus for Characterizing Coal Tar in Soil - 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. | 11-20-2008 |

| 20150330215 | SYSTEMS AND METHODS FOR MEASURING DOWNHOLE FLUID CHARACTERISTICS IN DRILLING FLUIDS - Disclosed are systems and methods for monitoring drilling fluids. One system includes a flow path containing a fluid having at least one component present therein, and a movable housing having at least one optical computing device configured to move with the movable housing along a detection path, the at least one optical computing device including at least one integrated computational element (ICE) configured to optically interact with the fluid over the detection path, wherein the at least one ICE is configured to detect a characteristic of the at least one component and generate an output signal corresponding to the characteristic. | 11-19-2015 |
| 20160017707 | Water Volume Fraction of Flowing Fluids - A measurement tool having one or more measurement cells disposed in a fluid flow path is provided. Measurements are made in each of the measurement cells and a fluid type is identified based on the outcome of the measurements. A numerical value is associated with each measurement cell based on the identified fluid type, and a total fractional volume of the identified fluids is determined using the associated numerical values. There may be a relatively large number of measurement cells distributed so as to substantially cover the cross-sectional area of the flow path, relatively few measurement cells distributed randomly in fixed locations in the flow path, or a single measurement cell moveably located in the flow path. The measurement cells measure a property such as resistivity, capacitance, dielectric constant, or electrical impedance. The total fractional volumes of the identified fluids may be determined using a statistic. | 01-21-2016 |
| 20160108730 | THREE-PHASE FLOW IDENTIFICATION AND RATE DETECTION USING ACOUSTIC GUIDE ARRAY - An apparatus for estimating a fraction of each component of a fluid of interest flowing in a cased borehole and a property of the fluid includes an acoustic waveguide sensor having a waveguide configured to guide an acoustic signal along a waveguide path and an array of acoustic transducers coupled to the waveguide for transmitting and receiving an acoustic signal, the acoustic waveguide sensor being configured to transmit and receive a compression-wave acoustic signal that is reflected off of the casing and transmit and receive a shear-wave acoustic signal that propagates along the path. A controller is coupled to the waveguide sensor and configured to perform a compression-wave acoustic measurement on the fluid using the acoustic waveguide sensor in order to estimate the fraction of each component of the fluid and to perform a shear-wave acoustic measurement in order to estimate the property of the fluid. | 04-21-2016 |
