  • Functional specification for a typical onshore wellhead control and monitoring system
    This document specifies the requirements for a control and monitoring system for an onshore low-pressure, low-temperature oil and gas wellhead. The described system and associated devices shall meet the functional, operational, electrical, and environmental requirements as outlined
  • Wellhead Pressure Interlock Protection
    There are many pressure related issues of concern in petroleum well production. Both high and low pressure conditions are indications of problems that must be addressed to maintain well safety and performance. A flexible and reliable control system for pressure monitoring provides a failsafe
  • Selection Of Natural Gas Wellhead Feedthroughs
    The importance of natural gas as an energy source for the United States has grown steadily since the mid-1990s. With continued political instability plaguing many of the worldâ s major energy producers, North American natural gas reserves provide an attractive option for energy independence. Natural
  • ProcessMaster electromagnetic flowmeter - The perfect fit for wellhead injection flow measurements
    When oil and gas are extracted, large amounts of brine water are typically brought to the surface. More than 140,000 wells in operation in the United States produce over 2 billion gallons of water every day. When states began to implement rules preventing disposal of brine water to surface water
  • Chapter Six: A New Era in Oil and Gas Flow Computing
    Traditionally, most oil and gas production sites used a flow computer at the wellhead for measurement and simple control functions, and a PLC at a central facility for more sophisticated control. Operational and measurement data was collected from the well site once an hour and that was good enough
  • A muddy challenge for oil supply chain
    An oil industry processing equipment supplier was experiencing a growing demand among. their oil & gas customers for equipment to handle the rigours of transferring drilling mud from. the wellhead. Not only does the equipment have to cope with the difficult mud itself, but also. sand rock
  • High Reliability PCB Design Tips for Aerospace and Other Harsh Environments
    Whether a sensor package is placed on an airplane, a spacecraft, or down the borehole of a wellhead, the cost of failure can often be measured in hundreds of lives or millions of dollars lost.For these situations, engineers have to pay particular attention to design choices. The following article
  • Foamy Oil PVT and Rheology Measurements (.pdf)
    gas drive reservoirs show anomalously good primary performance, high oil production, and primary recovery factor (Maini et al. 1993; Sheug. 1997). The oil is produced as oil-continuous foam that contains dispersed gas bubbles at the wellhead.
