Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Performing a bottomhole well pressure test while using a jet pump is challenging due to the need for separate equipment retrieval, which increases wellsite time and expense.
Innovation Solution
A fluid production system that integrates a jet pump with a well parameter recorder and check valves, allowing for simultaneous fluid production and pressure measurement, and enabling the jet pump and recorder to be retrieved together after the test.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a jet pump is used for producing fluid from the well, then fluid production is achieved, but separate equipment retrieval is required for pressure testing which increases wellsite time and expense
Solution Approach 1:
The patent combines the jet pump and pressure gauge into a single integrated assembly that can be deployed and retrieved together. The pressure gauge is positioned within the jet pump housing, allowing simultaneous fluid production and pressure measurement without requiring separate equipment trips to and from the wellsite.
Solution Approach 2:
The jet pump assembly is designed to perform multiple functions: it produces fluid from the well while simultaneously measuring pressure through the integrated gauge. This multi-functional design eliminates the need for separate pressure testing operations and equipment.

Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution allows for efficient bottomhole well pressure testing and reduces wellsite time and expense by enabling a single trip retrieval of the jet pump and recorder, while maintaining accurate pressure measurements.
Implementation Method 1
A jet pump uses the Bernoulli principle to draw production fluid toward a relatively low pressure region created when a power fluid pumped from surface flows through a nozzle and into a throat of the jet pump.

AI summary
An apparatus can include a jet pump with a nozzle and a throat, a flow passage for conducting production fluid to the throat, and a check valve that prevents flow from the throat to the flow passage and permits flow from the flow passage to the throat. A method can include performing a bottomhole well pressure test while measuring well pressure with a well parameter sensor connected to a jet pump, and then retrieving the well parameter sensor and the jet pump together from the well. A system can include a jet pump sealingly received in a tubular string, the jet pump including a throat that receives a power fluid from a nozzle and receives a production fluid from a flow passage, and a check valve permitting flow of the production fluid from the flow passage to the throat and preventing flow of the power fluid to the flow passage.
