  1. Endress+Hauser’s Multiparameter Levelflex FMP55 Solves Emulsion Interface Measurement In Separators

    A leading oilfield exploration company was having issues with a standard guided wave radar device that was directly installed into a separator measuring overall level and interface level. In guided wave radar devices, the microwave pulse emitted from the transmitter gets reflected at the air/oil interface (for overall level) is detected and part to pulse continues through the oil to the oil/water interface (for interface level) where a second reflection is created. However, if an emulsion (approximately > 2”) exists, then the guided wave radar will not work reliably as the reflection from the interface is greatly decreased.

  2. Level Interface Sensing For Water Dump Control In The Oil And Gas Industry

    Accurate and reliable detection of the interface between oil and water in a water dump tank improves the separation process

  3. Advances In Flowmeter Proving For Shale Fields

    In the past, calibrating flowmeters in remote shale fields required removing the meters and sending them to a calibration lab or using local provers. Now, mass and density calibration has come to the field.

  4. Improve Reliability And Decrease Alarm Count

    The purpose of this paper is to discuss how to decrease alarms due to redundant level devices not matching especially in applications with high pressure and/or high temperature. The importance of Gas Phase Compensation (GPC) and how it affects level readings of guided wave radar (GWR) devices is critical. The presence of polar gas also can have an effect on the accuracy of any GWR that does not have GPC when installed in applications where high temperature or pressure is present. This paper will discuss these issues and address how to overcome them.

  5. Performing A Storage Tank Risk Assessment

    Are your petroleum storage tanks ready for updates to API 2350? Here’s how to find out and address any issues.

  6. Advanced Tools Simplify Instrument Maintenance

    Hardware and software developments make preventive maintenance easier, lower costs, reduce parts inventories, and prevent unexpected equipment failures.

  7. Advances In Flowmeter Technology

    Thist article disucsses two trends turning the flowmeter industry on its ear: advances in flowmeter diagnostics and the adoption of smartphone-like technology to improve access and communications.

  8. Solving Difficult Level And Flow Measurement Problems In Crude Oil Production Processes

    Oil producers often deal with troublesome applications including water carry over into the oil leg of separators, entrained gas in oil and water legs, emulsion layers inside the separator, varying densities and remote areas. These concerns can be difficult for traditional instrumentation to measure, but modern level and flow instruments have been developed to successfully address these issues.

  9. Accounting For The Unaccounted

    In modern tank and terminal facilities, material transfer operations include a mix of legacy processing systems still in use, new technologies installed to improve operations, and tank monitoring software. But some older facilities have not modernized their operations, and can be losing millions of dollars in unaccounted losses, especially if they are dispensing more materials to customers than they are getting paid for. Conversely, errors can be made in the other direction, shortchanging and overcharging customers, leading to loss of business and other issues.

  10. Instrumentation For Produced Water Applications

    Produced water refers to any water brought up to the surface during oil and gas production, typically as the result of drilling, exploration and hydraulic fracturing. By Steven Smith, Product Business Manager – Analytical, Endress+Hauser
