In both scenarios, the cold finger tests conducted on the fluids in the laboratory identified the best product to be PI-7475 paraffin inhibitor, a specialty chemical designed to control wax deposition in oil and gas production and inhibit the formation of paraffin in tubing and flowlines.
Cold finger experiments had shown promising results with over 70% inhibition in the normal laboratory tests. In the atypical tests, the product demonstrated improved performance at equivalent dose rates with over 85% inhibition in a higher-rate test.
Demonstrate excellent wax inhibition
During product screening using the cold finger method, PI-7475 inhibitor demonstrated excellent performance on both samples. The product reduced wax deposition, resulting in the need for fewer and easier paraffin cleanout operations and less risk of pig sticking. PI-7475 inhibitor was implemented on all wells in the field, and subsequent reports showed continued reduction in wax deposition.
