Managing Lost and Unaccounted for Gas Volumes

(P&GJ) — Lost and unaccounted for (LAUF) gas is a calculated value that compares the amount of gas coming into a system (purchased) to the amount of gas leaving that system (sold or otherwise accounted for). Although LAUF is often equated to leaking pipes and equipment, leaks generally only represent a small portion of the value.

Importance of Moisture Analysis in Pipeline Transportation

(P&GJ) — Nearly every substance is affected by moisture, which can alter physical, chemical and electrical properties. When transporting hydrocarbons such as natural gas, the presence of moisture in the pressurized stream can create serious problems.

(P&GJ) — The oil and gas industry appears to be favoring a move toward using “newer” and more “advanced” flow measurement technologies, such as ultrasonic and Coriolis devices as an alternative to turbine and positive displacement meters.

New Leak Detection Rules for Pipelines Proposed

(P&GJ) — The federal pipeline safety agency has proposed major changes to its leak detection, based not on concerns about safety but rather in order to reduce methane emissions based on their contribution to climate change.

Proactive Integrity Management for Pipeline River Crossings

(P&GJ) — The selection of appropriate pipeline routes is critical for reducing the impact of geotechnical and hydrotechnical hazards. Many hazards, including water crossings, can be avoided by careful route planning.

Detecting Leaks Using Remote Sensing Pipeline Monitoring

(P&GJ) — Pipelines are incredibly valuable assets for the energy and resources industry. Not only are they the safest way to move petroleum and other products, but they are also the most cost-effective and sustainable option to do so.

Tackling Mega Rule Leak Detection Challenge by Air

(P&GJ) — Four years after part one of the PHMSA Mega Rule came into effect, the industry is still trying to get a handle on the full extent of the rule requirements and their implications.

Practical Approach to Critical Assessments and Evaluating Pipelines

(P&GJ) — Engineering Critical Assessments (ECA) have been incorporated into United States pipeline safety regulations1 as a means for reconfirming the maximum allowable operating pressure (MAOP) for onshore steel gas transmission pipelines, while engineering assessments (EA) have been a longstanding method for proving consistent conclusions and recommendations across a variety of situations in accordance with the guidance in Canadian standard CSA Z662:19.

U.S. State Department Warns China Could Hack Infrastructure, Including Pipelines

The U.S. State Department warned that China could launch cyber attacks against critical infrastructure, including oil and gas pipelines after researchers discovered a Chinese hacking group had been spying on such networks.

Value of Advanced Sensor Capabilities in Pipeline Management

(P&GJ) — For companies in the energy sector, optimizing systems and processes can bring as much growth as does innovating new products and services. Such optimization typically involves eliminating inefficient or unreliable steps in business systems and processes – a practice sometimes referred to as “getting the barnacles off the boat.”

Pipeline Operator TC Energy Finishes Recovering Oil from Kansas Creek in Keystone Spill

TC Energy Corp. finished recovering oil from a rural Kansas creek where its Keystone Pipeline spilled 14,000 barrels of oil in December, the company said on Friday.

Using Resonance Technique to Test Pipeline Weld Fatigue

(P&GJ) — Steel catenary risers (SCRs) are a critical element within many offshore pipeline installations. The ability of these risers to withstand the installation and in-service loading is vital to the success of the projects in which they are used.
