A Comparison of Instrumented and Surface-Controllable Rotary Honing and Brushing for Well Intervention

Abstract

Instrumentation and surface control improve the success rates and efficiency of wireline rotary brushing and honing. Data based operational planning and real-time data feedback allow for efficient operations with measurable outcomes. This paper compares two types of instrumented, wireline-powered rotary cleaning assemblies by assessing their performance, cleaning efficiency, operational factors, and real-time logging outputs. Basic rotary brushing physics along with characterization curves of the systems explain the relationship between operational factors including rotational speed, torque, and downhole power requirements. Models of the operational factors were created so that preoperational planning and real-time data interpretation can be used to verify intervention objectives.
