Metering & Measurement

Mastering Inspection of Challenging Pipelines

Any inspection device used internally must be introduced into the pipeline to be investigated. This implies that the line is accessible. “Piggable” lines need suitable launchers and receivers and are generally inspected in a unidirectional mode. If tool traps are not available or suitable, access has to be achieved via other means. Accessibility can be achieved through technical and/or procedural means.

Retrofitting Customized Valves, Actuators for Pipeline Monitoring Stations

Oil and gas engineers face a major problem in accurately and reliably measuring and monitoring the various fluids that are introduced into oil pipelines from well site pumping stations. A thorough understanding of both the oil separation process and the properties of valves and actuators is required to correctly specify a system that will sufficiently measure and monitor these various types of fluids. Also, the conditions downstream from each well are different, requiring valves and actuators to be highly customized to their specific role in the process.

GPR, EM Technologies Offer Rewards in Environmental Assessments

New Integrity Solutions Facing Many Same Old Problems

The protection of oil, gas and refined product pipelines against natural events such as earthquakes, hurricanes and tsunamis, not to mention human actions including construction excavations, illegal tapping and terrorist sabotage, is an ongoing concern for operators around the world. However, in the United States, the top three causes of pipeline failure reported by the Pipeline and Hazardous Materials Safety Administration (PHMSA) are construction excavations, corrosion and equipment failure (Figure1).

Mastering Inspection of Challenging Pipelines

Pipelines are a valuable asset and need protection. In order to achieve this, a modern pipeline integrity management program usually includes regular inspections followed by integrity assessment, and if required, repair and rehabilitation measures.

Natural Gas Production Records from Idaho Well Made Public

BOISE, Idaho (AP) — The first batch of production records from a natural gas well in Idaho have been made public following a new rule approved by lawmakers. The Idaho Department of Lands earlier this week released the monthly records that span from February 2013 to July for a well named State 1-17 in southwest Idaho and operated by Houston-based Alta Mesa. Records show the well is producing a comparatively small amount of natural gas — 290,000 cubic feet in July. The gas is being sent to Intermountain Gas and used in the nearby town of New Plymouth.

Orifice, Ultrasonic Meters in Wet Gas Flow Service

Natural gas producers regularly have to meter wet gas flow. Separator systems or multiphase wet gas meters are beneficial but the economic reality of many applications is that standard gas meters must be used. Hence, understanding the wet gas performance of gas meters is important.

ROSEN Sponsors Roundtable on Linear Threats

The ROSEN Group brought key industry stakeholders together for a roundtable on the topic of “Linear Threats in Pipelines” on May 28. The event attracted over 100 attendees from throughout North America and Europe who were hosted at the ROSEN facility in Gahanna, OH. The roundtable began with an official welcome by ROSEN Executive Vice President Chris F. Yoxall, who emphasized the importance of “why we are here.” He addressed the goal and set the tone for the day – bringing together all stakeholders to collectively work on common topics of interest.

Best Practices for Mitigating Flow Measurement Errors Associated with Hydrate Formation

Operating pipelines at high pressure and low temperature can lead to natural gas hydrate formation, even with modest water content. Hydrate formation is also a growing concern as flow measurement equipment and operators become more accustomed to handling wet gas flow. Hydrate particles can attach to pipe walls, instruments, and other structures within the pipeline, which can then lead to gas measurement errors or instrument failure due to solid particle attachment or high-velocity impacts.

Measuring Hydrocarbon Fluids Using Wet Gas, Watercut and Multiphase Meters

Oil and natural gas are two fossil fuels that account for a great deal of the energy used in the world. What they have in common is that they are found deep in the earth, sometimes underneath the ocean bed, and they have to be extracted through the drilling process. The fluids that come out of these wells generally include a mixture of gas, water, and oil. In addition, they may contain sand and sediment. These components eventually have to be separated and measured before they can be usefully processed.

Developing Engineering-Based Integrity Programs for Pipelines, Plants

Integrity assessment has always been a part of operations and maintenance activities. As plant piping and pipeline infrastructure has aged, industry first developed basic tools, and as their importance became apparent, these tools improved to meet those increasing needs.

Role of Quality Management System in Project Completion

Quality is critical and the most important factor for completion of a project on time and within the allocated budget. If proper quality checks are not in place, defective materials or work may cause damage to equipment and facilities, and potentially resulting in health and safety hazards. Successful projects are those that meet business requirements and are delivered on schedule. Many factors contribute to a project’s success such as project planning, resource allocation, risk management and governance criteria, but effective quality management is critical for any project success.
