AUTOMATED INFLOW NEGATIVE TEST PROCESS - A simplified explanation of the abstract
This abstract first appeared for US patent application 17937373 titled 'AUTOMATED INFLOW NEGATIVE TEST PROCESS
Simplified Explanation
The abstract describes a method for conducting an inflow negative test of a wellbore using a flow measuring sub in a drill string to measure fluid movement and determine the success or failure of the test.
- The method involves placing a flow measuring sub in a drill string to connect a drill pipe joint and a drill pipe.
- Fluid flow is directed downstream along an annulus and upstream along the drill pipe, reversing direction through an open port in the drill pipe or an open end.
- The fluid returns to a mud tank through the flow measuring sub and drill pipe joint, with measurement data sent to a computer device for analysis.
- The success or failure of the inflow negative test is determined based on the flow measurement data.
Potential Applications
This technology can be applied in the oil and gas industry for testing the integrity of wellbores and ensuring proper well control during drilling operations.
Problems Solved
This technology helps in detecting any inflow issues in a wellbore, allowing for timely intervention to prevent potential blowouts or other safety hazards.
Benefits
The method provides a reliable and efficient way to conduct inflow negative tests, improving overall wellbore safety and reducing the risk of accidents during drilling operations.
Potential Commercial Applications
This technology can be utilized by oil and gas companies, drilling contractors, and well service providers to enhance well control practices and ensure the integrity of wellbores.
Possible Prior Art
Prior art in this field may include similar methods for conducting inflow tests in wellbores using different types of flow measuring devices and techniques.

Original Abstract Submitted
A method to perform an inflow negative test of a wellbore is disclosed. The method includes disposing a flow measuring sub in a drill string to mechanically connect a drill pipe joint and a drill pipe, and sustaining a fluid flow downstream along an annulus and upstream along the drill pipe. The fluid flow reverses direction through an open port in a wall of the drill pipe or an open end of the drill pipe, and returns to a mud tank from the drill pipe through the flow measuring sub and the drill pipe joint. Flow measurement data of fluid movement through the flow measuring sub is generated using a measuring device of the flow measuring sub and sent to a computer device of the flow measuring sub. Accordingly, a success/failure result of the inflow negative test is determined using the computer device based at least on the flow measurement data.
