PASSIVE LOGGING WHILE LEVITATING (PLWL): CONTACTLESS CONVEYANCE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18048323 titled 'PASSIVE LOGGING WHILE LEVITATING (PLWL): CONTACTLESS CONVEYANCE
Simplified Explanation: The patent application describes a method for logging in a well using a Passive Logging while Levitating (PLWL) assembly to detect deviations in the wellbore and fluid flow direction, and levitating the logging assembly in the center of the wellbore for logging operations.
- Securing a PLWL assembly to a BHA to form a logging assembly
- Running the logging assembly into a wellbore
- Detecting wellbore deviations and fluid flow direction
- Activating PLWL assembly based on deviations and flow direction
- Levitating the logging assembly in the center of the wellbore
- Determining target depth and performing logging operations
Potential Applications: This technology can be used in oil and gas exploration and production industries for efficient well logging operations.
Problems Solved: - Improved accuracy in detecting wellbore deviations - Enhanced efficiency in fluid flow direction detection - Facilitates logging operations in the center of the wellbore
Benefits: - Increased precision in well logging - Time and cost savings in logging operations - Enhanced data collection for well analysis
Commercial Applications: Title: Advanced Well Logging Technology for Oil and Gas Industry This technology can be utilized by oil and gas companies for optimizing well logging processes, leading to improved decision-making and resource management.
Prior Art: No prior art information is provided in the abstract.
Frequently Updated Research: There is no information on frequently updated research related to this technology.
Questions about Well Logging Technology: Question 1: How does the PLWL assembly detect deviations in the wellbore? Answer: The PLWL assembly detects deviations in the wellbore by analyzing changes in its position and orientation as it moves through the wellbore.
Question 2: What are the key advantages of levitating the logging assembly in the center of the wellbore? Answer: Levitating the logging assembly in the center of the wellbore allows for more accurate and reliable logging data to be collected, as it reduces interference from the wellbore walls and surrounding fluids.
Original Abstract Submitted
A method for logging in a well is disclosed. The method includes securing a passive logging while levitating (PLWL) assembly to a bottomhole assembly (BHA) to form a logging assembly and running the logging assembly into a wellbore of the well. The method further includes detecting a deviation in the wellbore, detecting a fluid flow direction around the logging assembly in the wellbore, activating the PLWL assembly based, at least in part, on the deviation in the wellbore and the fluid flow direction, and levitating the logging assembly in a center of the wellbore. The method also includes determining whether the logging assembly has reached a target depth and performing logging in the well while the logging assembly is levitating in the center of the wellbore.
