REMOTE FIELD EDDY CURRENT TOOLS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18531503 titled 'REMOTE FIELD EDDY CURRENT TOOLS
Simplified Explanation
The method described in the patent application involves estimating the thickness of a first pipe within multiple nested conductive pipes using electromagnetic pulsed tools and remote-field eddy current (RFEC) look-up curves.
- Using an electromagnetic pulsed tool to gather log measurements at different depths within multiple nested conductive pipes in a wellbore.
- Generating RFEC look-up curves based on normalized signal level responses for the multiple nested conductive pipes.
- Selecting an RFEC look-up curve that indicates the thickness of the first pipe based on the time decay response.
Potential Applications
This technology could be applied in the oil and gas industry for wellbore integrity assessment and monitoring of pipe thickness in complex well structures.
Problems Solved
This technology solves the problem of accurately estimating the thickness of a specific pipe within multiple nested conductive pipes, which can be challenging using traditional methods.
Benefits
The benefits of this technology include improved accuracy in pipe thickness estimation, which can lead to better decision-making in wellbore maintenance and integrity management.
Potential Commercial Applications
One potential commercial application of this technology could be in providing wellbore inspection services to oil and gas companies, offering a more advanced and reliable method for assessing pipe thickness.
Possible Prior Art
One possible prior art in this field could be the use of electromagnetic tools for wellbore inspection and monitoring, but the specific method of using RFEC look-up curves for estimating pipe thickness within nested conductive pipes may be a novel innovation.
Unanswered Questions
How does this technology compare to traditional methods of pipe thickness estimation in terms of accuracy and efficiency?
This article does not provide a direct comparison between this technology and traditional methods, so it is unclear how they stack up against each other in terms of accuracy and efficiency.
What are the potential limitations or challenges in implementing this technology in real-world wellbore environments?
The article does not address any potential limitations or challenges that may arise when implementing this technology in actual wellbore environments, leaving room for further exploration of practical considerations.
Original Abstract Submitted
Some implementations include a method for estimating a first pipe thickness of a first pipe within multiple nested conductive pipes, the method comprising: forming a measured log including a set of log measurements at different depths using an electromagnetic pulsed tool disposed in multiple nested conductive pipes in a wellbore; generating a plurality of remote-field eddy current (RFEC) look-up curves based on measurements of normalized signal level responses for the multiple nested conductive pipes at one or more points in a time decay response; and selecting an RFEC look-up curve from the plurality of RFEC look-up curves at a point in the time decay response that indicates the first pipe thickness of the first pipe.
