MaurerLab has introduced American Maurer company's physical casing wear tester (US DEA-42 project research results) and CWEAR casing wear prediction software to evaluate different lateral force (maximum 14 kN), different mud systems and additives (such as iron ore, barite, etc.), different speeds (maximum 158 rpm) and different wear-resistant materials on casing friction coefficient and wear rate of the quantitative test experiments.
