Wax deposition is a severe flow assurance challenge that threatens waxy crude oil
production and transportation. For wax remediation, pipeline pigging is the most widely used …

In flow assurance of crude oil pipeline transportation, pig stalling and wax blockage in
pigging could cause complete shutdown of the whole pipe. In consequent wax remediation …

In this work, a theoretical model for estimating the wax breaking force and wax removal
efficiency of cup pig is developed. The proposed model is physically built upon orthogonal …

To predict the motion of a pig to estimate its velocity, position and required driving pressure
is essential before pigging. The frictional force between a pig and the pipeline is a key …

Pigging is widely used in pipelines for wax removal. However, pigging operation relies
heavily on “rules of thumb.” Because of its complexity, rather-limited pigging models were …

Pipeline pigging is a major conventional wax remediation technique for waxy crude oil
transportation. Predicting the wax breaking force, a decisive parameter for pigging …

Pigging is widely used in pipelines for wax removal. However, pigging operation relies
heavily on “rule-of-thumb.” Because of its complexity and lack of methods, the wax removal …

Pigging has been recognized as the most cost-effective method for preventing flow
restriction by wax deposits in subsea flowlines. However, the pigging mechanics for wax …

Pipeline inspection gauge (pig), as a kind of pipeline robot, is commonly used in oil and gas
pipelines during different stages of operation to perform functions such as dewatering …

Mechanical pigging is the most conventional method to mitigate the wax deposition in the
field pipeline. However, wax removal physics of foam pig is still poorly understood. In this …
