Lost and Unaccounted For: Measurement Operations Adapting to Technology
With the advent of smart, electronic metering technology, such as ultrasonic meters and online gas chromatographs, the diagnostics information available at metering facilities has increased exponentially. Likewise, advancements in networking has made collecting the diagnostics data possible.
Using Pressure Regulators for Site Distribution in Natural Gas Pipelines
The purpose of codes covering higher-pressure natural gas distribution systems is to provide a basis of design for the pipeline and all the components connected to the downstream system, including valves, control valves, regulators, meters, pressure vessels and other components connected to the piping system.
Flexible Flow Meter Sector Positioning Itself for Better Times
Even though gas flow can be a difficult measurement to make, flow meter suppliers are continually identifying novel solutions for this task.
Aligning Operating Procedures with Land Management Orders
In 2016, the Bureau of Land Management (BLM) published revisions to the Oil and Gas Measurement Regulations (43 CFR 3170s) for conducting oil and gas operations on federal and native American lands.
Technology Meets Mega Rule Materials Verification Challenge Head On
With the implementation of the Mega Rule, U.S. pipeline owners and operators will be required to provide traceable, verifiable and complete (TVC) records that confirm the physical and operational characteristics of the pipeline meet the new requirements.
Correct Pigs, Procedures for Hydrostatic Testing of New Pipelines
Laying a cross-country pipeline is expensive. Many hours of engineering and planning must meet certain standards and regulations and receive federal government approval before starting construction. It costs approximately $100,000 per diameter-inch-mile to build a pipeline in a reasonable lay area. This number can easily triple in marsh lands, hills, mountains and rocky terrain. In those areas it could cost about $20 million to lay 100 miles (161 km) of 20-inch pipe.
For Inspection and Pressure, How Low Can the Gathering Sector Go?
As natural gas assets are beginning to age, there is a larger need for integrity solutions in this area. The challenge with these assets is that they often operate at lower pressures, which can make running a conventional inline inspection tool difficult.
Evolution of Ultrasonic Inline Inspection
Inline inspection (ILI) by means of intelligent pigging has become a standard application to ensure the safe operation of pipelines worldwide. Ultrasonic inspection tools have proven successful for crack and metal loss inspections of liquid pipelines.
Our World Is Moving – And So Are The Pipelines
Strain assessments and pipeline movement assessments allow operators to identify and mitigate threats presented by geohazards.
Separating Pipeline Integrity Management’s Wheat from Its Chaff
Natural gas and hazardous liquids pipeline operators have been accumulating mass volumes of data for several years. But what to do with all this data? This is a question many natural gas pipeline operators are asking in advance of the highly anticipated Pipeline and Hazardous Materials Safety Administration’s (PHMSA) proposed gas and gathering pipeline mega-rule.

Good measurement practices suggest flow measurements should occur without instabilities or pulsations in the flow. Even minor inaccuracies in the measurement of high value products can lead to significant financial exposure over extended periods of time.
Using Computational Fluid Dynamics When Equipment Fails
The importance of accurate measurement cannot be under-estimated. In 2012, the oil price was above $100 per barrel, but only a year later, as oil prices began to decline, the average price of a barrel of crude oil was $91, dropping to $42 by 2015.
