​Oilfield pipeline pigging operations are an essential part of maintaining and cleaning pipelines in the oil and gas industry. A “pig” is a cylindrical device that is inserted into the pipeline and propelled through the pipeline by the flow of oil or gas. These pigs are used to perform various tasks such as cleaning, inspection, and separation of different products in the pipeline.

The pigging process involves sending the pig through the pipeline at a controlled speed using either water or air pressure. The pig scrapes along the inside of the pipeline, removing any deposits or debris that may have accumulated over time. This process is known as “cleaning pigging” and helps to maintain the efficiency of the pipeline by preventing blockages that could impede the flow of oil or gas.

Another type of pigging operation is known as “inspection pigging.” This involves inserting a pig equipped with sensors and cameras into the pipeline to inspect its condition, identify any leaks or corrosion, and measure the thickness of the pipeline walls.

A third type of pigging operation is called “batch pigging.” In this process, a pig is used to separate different products in the pipeline, such as oil and water. The pig is designed to capture and collect the specific product it is separating from the pipeline, allowing for more efficient and accurate product separation.

In summary, oilfield pipeline pigging operations are essential for maintaining the integrity, efficiency, and safety of pipelines in the oil and gas industry. They help to remove debris, inspect the condition of pipelines, and separate different products in the pipeline.
