Jet Pump Carrier Data Tool Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data recording systems for jet pumps in oil and gas wells require significant cost and effort to obtain downhole pressure and temperature data, often necessitating the removal of the entire tubing string and jet pump assembly, which is undesirable.
Innovation Solution
A system where a carrier with a venturi nozzle and data tool housing is seated within the jet pump body, allowing data acquisition without pulling the tubing, using power fluid to install and retrieve the carrier, and a data tool for real-time data sensing and storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If recording equipment is installed on the end of a jet pump production assembly, then downhole pressure and temperature data can be obtained, but the entire tubing string and jet pump assembly must be pulled from the well requiring a service rig or coiled tubing unit
Solution Approach 1:
The system divides the jet pump assembly into separate functional components: the jet pump body remains in the well, while the carrier with data tool housing can be independently installed and retrieved. This segmentation allows data acquisition without requiring complete removal of the production assembly.
Solution Approach 2:
The data tool housing is extracted from the traditional requirement of being attached to the end of the production assembly. Instead, it is integrated into a carrier that can be independently manipulated, allowing data retrieval without extracting the entire tubing string and jet pump assembly.
2Measurement precision
If the jet pump is installed in a sliding sleeve assembly for data recording, then data can be accessed, but a wireline service unit must perform several trips in-hole to retrieve components and re-run the jet pump
Solution Approach 1:
The system combines the data tool housing with the carrier that is already part of the jet pump's power fluid delivery mechanism. This integration allows the carrier to be used for both power fluid delivery and data acquisition, eliminating the need for separate wireline trips to install and retrieve data recording components.
Solution Approach 2:
The carrier serves multiple functions: it delivers power fluid to the jet pump and simultaneously houses the data tool for acquiring downhole pressure and temperature data. This multi-functionality eliminates the need for separate wireline service trips that would be required if data recording were a separate function.
3Measurement precision
If traditional recording equipment is used with jet pumps, then downhole conditions can be monitored, but significant cost and effort are required to install and retrieve the equipment
Solution Approach 1:
The carrier is designed to be self-sufficient for data acquisition. It contains its own data tool housing with sensors that can independently measure and store downhole pressure and temperature data without requiring external service equipment for installation or retrieval.
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
Enables the acquisition and retrieval of downhole data without pulling the jet pump or tubing, reducing operational costs and complexity, and allowing real-time data access without disrupting production.
Implementation Method 1
The carrier includes a venturi nozzle, venturi gap, and mixing tube in series in fluid communication with tubing for delivering power fluid to the venturi nozzle along a first flow path. Flow along the first flow path results in a low-pressure condition at the venturi gap. The low-pressure condition draws the wellbore fluid into the jet pump body at the intake and to the venturi gap.
Data Source
AI summary
A jet pump, a jet pump data tool system, and method of use thereof. The jet pump includes a body having an intake, a first aperture, and a second aperture between the first aperture and the intake. A carrier is seated in the body and receivable in the first aperture. The carrier includes a venturi for drawing wellbore fluid from the intake into the venturi. A housing for a data tool extends from the carrier. The housing is in fluid communication with the intake for allowing wellbore fluid to be exposed to the data tool. The carrier is seatable in the body by flowing power fluid and the carrier into the first aperture. The carrier is retrievable from the body by flowing power fluid into the second aperture.
