Paraffin production problem
Paraffin’s, associated with the crude oil production, can cause several production problems, naturally occurring paraffin occurs when the formation temperature is lower than the cloud point of the produced oil. The crystals that solidify increase fluid viscosity and can form deposits on pipeline walls and settle in vessels. Once accumulated in vessels, they form at tank bottoms and pads at fluid interfaces. If unchecked, this wax deposition can rapidly produce plugs that can choke off production tubing or pipelines, increase pumping pressure, slow down or stop production.
Paraffin created by hot oil/water treatments can cause damage due to heavier ends being pushed ‘downhole’ and into the formation. Both types of damage reduce the effective permeability at/or near the formation face, reduce the internal diameter of tubulars and pipelines, restrict or block valves, impede other production equipment to reduce capacity, and in the worst case stop production.
A group of dissolvers and dispersant fluids for paraffin deposits. They are also effective in removing blockage from flow lines and downstream equipment. Based on the different field condition the deposition and accumulations of paraffin will be different. Accordingly, a use of one of our solvents might be proposed.
Paraffin deposition could result within the formation if contacting the formation crude oil with a cold stimulation fluid.
The dispersant/solvent is used for remove asphaltenes from formation minerals prior stimulation treatment. Continuous treating may be required to inhibit asphaltene deposition in downhole. Batch treatments are common for surface equipment and tank bottoms. There are also asphaltene precipitation inhibitors that can be used by continuous treatment or squeeze treatments
