Chemicals can aid in minimizing disruptions in the production cycles of a producing well. Chemicals can aid in the reduction of a corrosion rate; they can assist in the enhancement of oil and water separation; they can reduce the amount of solids produced from, or injected into, wells; they can even assist in the optimization of natural gas production. While they can have many positive economic attributes, chemicals can also have an impact on our safety and environmental performance. However, for chemicals to be effective, the field conditions must be correctly evaluated, and the proper chemical identified and applied. This school will present an overview of production chemicals, the testing processes utilized for the selection of a product, and will present the attendees with an understanding of the analytical tests used to track and monitor their performance.
