  • Patent number: 8707779
    Abstract: A system for measuring and monitoring the internal liquid within a three phase separator allows a user to accurately and reliably calculate the volumetric flow rate of the liquids exiting the three phase separator. For each liquid inside of the three phase separator, a differential pressure device is attached to where the extension fitting enters its respective liquid. Once a dump valve is actuated, the extension fitting guides its respective liquid out of the three phase separator, and the differential pressure device creates a differential pressure within the respective liquid. A sensor reads the differential pressure through a pair of sensing lines. The sensor relays the differential pressure reading to an RTU flow computer that calculates the volumetric flow rate of the liquid exiting the three phase separator. The calculation is then sent to a SCADA system, which allows the user to observe the volumetric flow rate in real time.

  • Patent number: 7520166
    Abstract: A method analyzes the hydrocarbon composition of geological strata. The method includes an analysis of gaseous hydrocarbon concentrations contained in drilling muds. According to the method, for a given depth range, gaseous hydrocarbon concentration ratios are established in pairs at essentially-identical depths. Subsequently, a sub-set of the ratios is selected in order to form a signature that is representative of the gaseous hydrocarbon composition of the depth range. The aforementioned signature is defined by the at least one straight line representing the concentration of a first gaseous hydrocarbon in relation to the concentration of a second hydrocarbon. The signature is then compared to reference signatures in order to determine the hydrocarbon concentration of the geological stratum corresponding to the depth range.

  • Patent number: 7272973
    Abstract: Methods and systems are provided for evaluating subsurface earth oil and gas formations. More particularly, methods and systems are provided for determining reservoir properties such as reservoir transmissibilities and average reservoir pressures of a formation layer or multiple layers using fracture-injection/falloff test methods. The methods herein may use pressure falloff data generated by the introduction of an injection fluid at a pressure above the formation fracture pressure in conjunction with a fracture-injection/falloff test model to analyze reservoir properties. The fracture-injection/falloff test model recognizes that a new induced fracture creates additional storage volume in the formation and that a fracture-injection/falloff test in a layer may exhibit variable storage during the pressure falloff, and a change in storage may be observed at hydraulic fracture closure.

  • Publication number: 20040144169
    Abstract: An improved fluid flow sensor for measuring changes in temperatures of fluids flowing through apertures of a multiple-layered gasket is embedded between layers of the gasket. A thermal resistor type of sensor based upon hotwire anemometer technology in a preferred embodiment is responsive to changes in fluid temperature and flow velocity. A primary resistance with external current leads and separate auxiliary leads for voltage sensing are employed, wherein changes in resistance are virtually linearly proportional to changes in temperature. A four-point probe measurement method provides a most accurate reading of the temperature data to the extent that resistance associated with lead and contact resistances are minimized. The thermal resistor sensor is constructed of relatively thin layers of dielectric and electrically conducting materials having a low thermal mass, wherein the dielectric layers serve as support and electrical insulation to protect the sensor from environmental deterioration.
