Navigating Small Diameter ILI Challenges in Crude Oil Gathering Systems
Bridger Pipeline operates a crude oil gathering system, of approximately 3,500 miles, in the Williston Basin of western North Dakota, eastern Montana and the Powder River Basin of Wyoming. The system contains many small-diameter (3-inch to 6-inch) gathering lines that are a challenge to inspect with ILI tools.
Experts See Polymers Among Keys to Better Pipe Protection
Leaders within the coatings industry have indicated that there are a number of innovative products and services that have been developed recently, which enhance corrosion control and provide better pipeline coatings.
Common Challenges with Field-Applied Liquid Epoxy Pipeline Coatings
Coatings are an incredibly important part of maintaining safe pipeline operations and asset integrity, including being a first line of defense against corrosion and corrosion-induced failures.
Coating Versatility Can Assist with Better Flow Efficiency
Corrosion control is an important factor when it comes to maintaining the integrity and safety of pipelines. Given the growing need for energy transportation it's crucial to shield pipelines from corrosion in order to ensure their longevity and prevent any leaks or failures.
Evacuation Technologies to Reduce Methane Releases During Pigging
Due to the strong global warming potential (GWP) of methane (CH4), there is increasing attention on reducing its releases (both unintentional and intentional) into the atmosphere.
Oxygen Corrosion Control for Multiphase, Gas Phase Pipelines
(P&GJ) — The oil and gas industry is committed to driving greater production and transportation from existing infrastructure, and ensuring effective asset integrity and flow assurance is essential to this objective.
US Pipeline Regulator Awards $15 Million Grants to Improve Safety
The U.S. Department of Transportation's Pipeline and Hazardous Materials Safety Administration (PHMSA) on Wednesday awarded $14.8 million in grants for pipeline safety training and technological research.
Non-Intrusive Pig Signallers: Cutting Costs, Emissions, and Environmental Risks
By their nature, non-intrusive pig signallers do not require a nozzle hole for any type of welded fitting, whether it be a 'counter flange' or a direct fitting like a threadolet. They are simply secured to the pipeline. Simultaneously, this approach saves costs on welding, non-destructive testing, and eliminates the risk associated with potential hydrocarbon leak paths.
Case Study: Rescue Pigging’s Race Against the Clock
(P&GJ) — A routine sphering operation to control liquid hold up on a 30-inch trunk pipeline transporting wet gas was interrupted when a sphere became damaged and stalled in the pipeline following interaction with a subsea isolation valve inadvertently stuck in the partially closed position.
An Operator’s Perspective: How to Comply with New US Gas Gathering, ILI Regulations
(P&GJ) —Traditionally, most gas gathering lines were small-diameter, low-pressure systems traversing sparsely populated areas, posing little risk from a business, safety, and environmental perspective. More recently, the volume of gas transported through gathering systems has increased significantly due to the advancements in horizontal drilling and hydraulic fracturing techniques.
Pig Removal: Recovering an Obstruction in Pressurized 48-Inch Pipeline
(P&GJ) —Following the completion of an offshore pipeline isolation project, STATS were asked by the client if they could offer a solution to a problem of an obstruction in their 48-inch gas export pipeline. During routine launching of an inline inspection tool, a slipper tray was accidently carried into the pipeline and lodged in the first pipeline bend, above grade, about 39 meters from the launcher door.
Tech Notes: Unpiggable In-Line Inspection Completed in South America
(P&GJ) — A team of Dexon pipeline engineers recently completed the inspection of a 20-mile (32-km), 3-inch diameter unpiggable or “challenging” underground petrochemical distribution pipeline, running from an onshore processing facility to a port on the South American coast.
New Approach to Digital Pipeline Integrity Management
(P&GJ) — Pigging is an operation that is regularly required by pipeline operators for both cleaning and data collection (intelligent pigging). Managing pigging schedules and risks is a significant challenge to operators/pigging vendors without an intimate knowledge of the pipeline.
Nanoparticles Transform Pipeline Cleaning, Integrity Management
(P&GJ) — Oil, gas, and multi-phase pipelines can be fouled with several types of deposits or internally restrictive debris. The actual type of fouling is dependent upon several factors including: the production fluid characteristics such as hydrocarbon product, water, and gas composition; the presence and composition of common oilfield contaminants, such as hydrogen sulfide, carbon dioxide, mercury, arsenic, zinc, lead, iron, and manganese and operating conditions (e.g., temperature, pressure, pH, flow regimes, etc.).
Proper Cleaning and Storage of Pipeline Pigs
Proper storage and maintenance are important to ensure the optimal performance and condition of urethane pigs.

Options for Internal Inspection of Difficult-to-Check Pipelines
Pipelines are essentially cylindrical pressure vessels. Any medium transported must not leak out. Each built to a specific design pressure, they must be operated efficiently and effectively to ensure not just safety and environmental protection but also optimum performance.
Managing Integrity for Subsea Pipelines Without Pigging
The Pipeline and Hazardous Materials Safety Administration estimates that 40% of the world’s pipelines are difficult to pig or are deemed “unpiggable,” which means they cannot be inspected via inline inspection, but their integrity still needs to be maintained.
