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.

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.

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.
