In the oil and gas industry, production teams are constantly on the lookout for issues that can cause a reduction in flow or inhibit proper operation of the well equipment. A chemistry equation for the best of them, petrochemical extraction needs to be properly monitored in order to ensure that operations are progressing in an efficient manner. One such problem can include the buildup of paraffin wax within the pipeline, which can lead to equipment failure, production decline, storage tank plugging and other issues that can result in expensive remediation. This necessitates the inclusion of paraffin inhibitor chemicals and wax inhibitors into the oil wellbore as well as storage tanks to prevent or minimize the paraffin deposits.
HOW TO PARAFFIN INHIBITORS WORK?
When hydrocarbons depressurize and cool during the process of extracting crude oil, the naturally occurring paraffins in crude oil can form crystalized structures that can then become deposited on the sides of pipelines, reducing the amount of space within and thereby reducing the speed and capacity for oil to flow through these pipelines. This can cause a buildup in pressure, reducing output and causing many other work stoppages that can lead to production companies losing valuable time and money.
Working to limit stoppages to fuel flow, flow assurance processes and paraffin in inhibitors are designed to mitigate the risks of solids accumulating in pipelines and allow for continual flow through the pipelines. Using the two pronged approach of both pre-site analysis and continual evaluation allows for effective operations and prevention of recurrent issues by looking at the problem from multiple angles in order to enact a mitigation and remediation plan for the production site.
Paraffin inhibitors are specially formulated chemicals that are injected into the well to minimize the buildup of paraffin deposits. These chemicals are formulated according to the well site location and conditions such as extreme temperatures, presence of water, and other considerations in order to create a formula that is both cost effective and stable during use. Paraffin inhibitors modify the shape and size of the wax crystals to disperse back into the crude in order to maintain steady flow.
When buildup already exists, paraffin dissolver chemicals can be introduced into the well in order to break up the paraffin wax deposits. With a combination of mechanical, thermal and chemical techniques, it is possible to recapture optimal oil flow and resume operations, although the time and money involved in remediating buildup does affect the bottom line of the production platform. Taking a proactive, rather than reactive approach, paraffin inhibitors can be incorporated into production chemicals in varying concentrations, outperforming solvent-based products in order to improve thermal stability and material compatibility. By improving the viscosity of crude oil while maintaining temperature controls, this prohibits the paraffin that is naturally present in crude oil from crystalizing and causing troublesome buildup not only in production pipelines but in storage tanks and vessels as well.
