ABSTRACT
Most crude oils include paraffin that crystallize in low temperature to create cluster, precipitated in the form of sediments and making the free flow of oil more difficult. Such situations take place mainly in the autumn-winter season. Created sediments settle on the surfaces of mining equipment, pipes and reservoirs. This situation cause exploitation difficulties connected with increased flow resistance and in consequence decrease or lack of oil flow in pipelines. In order to protect of pipes and machinery against the creation of sediments, a paraffin inhibitor must be introduced.
The Oil and Gas Institute in Poland has invented a new and effective paraffin inhibitors which can be dosed continually into machinery working in wellbores and transmission pipelines. Our paraffin inhibitors prevent paraffin settlement on the surfaces of machinery and pipelines as well as lower crude oil viscosity which facilitates free flow.

INTRODUCTION
Paraffin inhibitors, are used as a crude oil additive to crude oil in the process of drilling, transport and storage. They prevent settlement of paraffin on machinery working in wellbores, on the surface of transmission pipelines and reservoirs. They also lower pour point and viscosity. Paraffinic crude oils, which are a major portion of welled oils, contain paraffin hydrocarbons with high pour point, which in conditions of increased temperature existing in the deposits are dissolved in crude oil. During the welling process for crude oil, as a result of the fall in temperature, especially in the autumn and winter, paraffinic hydrocarbons crystallize. Crystals have a tendency...
