Paper: Applications and Advantages of High-Density Liquid Corrosion Inhibitors

High density liquid corrosion inhibitors have many advantages over conventional inhibitors in problem well treatments. High fluid level pumping wells, low pressure gas wells, high pressure gas wells, flowing wells with packers and wells with static water columns in tubing strings that have been difficult or impossible to treat with conventional inhibitors can now be treated effectively and economically with high-density liquid corrosion inhibitors. These inhibitors cut equipment costs, eliminate emulsion problems, swabbing expense, eliminate need for circulation of pumping wells, and in many cases cut frequency requirements for treatments. High density liquid corrosion inhibitors are available for both "sweet" and "sour" well fluids and for wells which produce a high percentage of water or practically no water from the formation.
