PIPE DRIFTING IN WELLS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18171947 titled 'PIPE DRIFTING IN WELLS
The abstract describes a method involving a drift bar and a tubular being lowered into a well, with the drift bar having a lower density than the wellbore fluid in the well.
- The drift bar is designed to pass through the inner bore of the tubular as it is lowered into the well.
- The presence or absence of the drift bar floating at the surface level is detected to determine if there is a restriction in the inner bore of the tubular.
- This method allows for the detection of restrictions in the tubular without the need for complex equipment or procedures.
- By using the drift bar as an indicator, potential blockages or obstructions in the tubular can be identified quickly and efficiently.
- This innovation can improve the efficiency and safety of well operations by providing real-time feedback on the condition of the tubular.
Potential Applications: - Oil and gas drilling operations - Wellbore maintenance and inspection - Geothermal drilling projects
Problems Solved: - Quickly identifying restrictions in tubulars - Improving operational efficiency - Enhancing safety measures in well operations
Benefits: - Real-time detection of blockages - Cost-effective solution for tubular inspection - Minimizes downtime during drilling operations
Commercial Applications: Title: "Drift Bar Tubular Detection System for Well Operations" This technology can be utilized by oil and gas companies, drilling contractors, and well maintenance service providers to streamline operations and reduce the risk of costly downtime.
Questions about the technology: 1. How does the drift bar help in detecting restrictions in the tubular?
- The drift bar's density difference allows it to float at the surface level, indicating any obstructions in the tubular.
2. What are the potential cost savings associated with implementing this technology?
- By quickly identifying blockages, companies can avoid costly downtime and maintenance expenses.
Original Abstract Submitted
A drift bar is lowered into a well. The drift bar has a density that is less than a density of a wellbore fluid residing in the well. A tubular is lowered into the well below a surface level of the wellbore fluid residing in the well. The tubular defines an inner bore having an inner diameter that is greater than an outer diameter of the drift bar. The drift bar is positioned to pass through the inner bore of the tubular as the tubular is lowered into the well. After the tubular is positioned below the surface level, an absence or presence of the drift bar floating at the surface level is detected. An absence or presence of a restriction in the inner bore of the tubular is determined in response to detecting the presence or absence, respectively, of the drift bar floating at the surface level.
