The Summary of the Scale and the Methods to Inhibit and Remove Scale Formation in the Oil Well and the Gathering Line

Reducing scale formation in an oil well, airtight gathering and transportation system presents a challenge for oil and gas production. This paper focused on the scaling phenomena in hydrocarbon production and reviewed on patents of scale removal technology and scale inhibition technology. The disadvantage and the mechanism of the scale formation were discussed, and the methods to solve this problem were summarized. The role of the green additive in affecting the scaling was discussed in relation to the principal mechanisms by which the inhibitors function.
