LINER TOP DIAGNOSTIC TOOL - A simplified explanation of the abstract

This abstract first appeared for US patent application 17986593 titled 'LINER TOP DIAGNOSTIC TOOL

Simplified Explanation

The patent application describes a method for testing in a well using inflow packers and diagnostic tools to ensure seal integrity and identify leaks.

Inflow packers are run into a hole in a locked position downhole.
A liner top diagnostic tool is run on a drill pipe to a desired depth.
A lower-packer-sized ball is dropped into the well to activate a lower inflow packer assembly.
The lower inflow packer assembly is pressure-tested to ensure seal integrity.
The lower inflow packer is unset by withdrawing string weight while rotating the string.
The drill string is displaced to test fluid to the end of the string, and weight and rotation are applied again to set the lower inflow packer.
A Homer plot is established based on an inflow test.
A deactivation-sized ball is dropped to deactivate the lower inflow packer assembly.
An upper inflow packer assembly is activated using an upper-packer-sized ball.
A leak is identified based on testing both liner tops.

Potential Applications

This technology can be applied in oil and gas well testing, well completion operations, and wellbore integrity assessments.

Problems Solved

This technology solves the problems of ensuring seal integrity in wellbore operations, identifying leaks, and conducting efficient and accurate well testing.

Benefits

The benefits of this technology include improved wellbore integrity, increased efficiency in well testing operations, and reduced downtime due to accurate leak identification.

Potential Commercial Applications

Potential commercial applications of this technology include oil and gas exploration and production companies, well testing service providers, and companies specializing in wellbore integrity assessments.

Possible Prior Art

One possible prior art could be the use of traditional packers and diagnostic tools in well testing operations. Another could be the use of similar methods for seal integrity testing in wellbore operations.

Unanswered Questions

How does this technology compare to traditional well testing methods?

This article does not provide a direct comparison between this technology and traditional well testing methods. It would be interesting to know the efficiency, accuracy, and cost-effectiveness of this method compared to traditional approaches.

What are the potential limitations of this technology in different well conditions?

The article does not address the potential limitations of this technology in various well conditions, such as high-pressure environments, deep wells, or unconventional reservoirs. Understanding these limitations is crucial for assessing the applicability of this technology in different scenarios.

Original Abstract Submitted

Systems and methods include a method for testing in a well. Inflow packers are run into a hole in locked position downhole. A liner top diagnostic tool is run on a drill pipe to a desired depth. A lower-packer-sized ball is dropped into the well to activate a lower inflow packer assembly. A back side of the lower inflow packer assembly is pressure-tested to ensure seal integrity. The lower inflow packer is unset by withdrawing string weight while rotating the string. The drill string is displaced to test fluid to the end of the string, and weight and rotation are applied again to set the lower inflow packer. A Homer plot is established based on an inflow test. A deactivation-sized ball is dropped to deactivate the lower include packer assembly. An upper inflow packer assembly is activated using upper-packer-sized ball. A leak is identified based on testing both liner tops.
