PIPE DRIFTING IN WELLS - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240280013 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 tubular is lowered below the surface level of the wellbore fluid and the drift bar passes through the inner bore of the tubular. 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.
- Drift bar with lower density than wellbore fluid is lowered into a well.
- Tubular with inner bore larger than drift bar's outer diameter is lowered below surface level of wellbore fluid.
- Drift bar passes through inner bore of tubular as it is lowered into the well.
- Presence or absence of drift bar floating at surface level is detected.
- Presence or absence of restriction in inner bore of tubular is determined based on drift bar's position.
Potential Applications: - Oil and gas drilling operations - Wellbore fluid management systems - Subsurface fluid flow monitoring
Problems Solved: - Efficient detection of restrictions in tubulars - Improved wellbore fluid control - Enhanced wellbore integrity maintenance
Benefits: - Increased operational efficiency - Reduced downtime for maintenance - Enhanced safety in drilling operations
Commercial Applications: Title: "Innovative Tubular Drift Bar System for Enhanced Wellbore Fluid Control" This technology can be used in oil and gas drilling companies to improve wellbore fluid management, leading to cost savings and increased productivity in drilling operations.
Prior Art: Further research can be conducted in the field of wellbore fluid control systems and tubular monitoring technologies to explore existing solutions and advancements in the industry.
Frequently Updated Research: Stay informed about the latest developments in wellbore fluid control systems and tubular monitoring technologies to ensure the implementation of cutting-edge solutions in drilling operations.
Questions about Tubular Drift Bar System: 1. How does the density of the drift bar impact its performance in the well? 2. What are the potential challenges associated with detecting restrictions in the inner bore of the tubular?
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.
