Free-point Indicator Tools (VFPT)
Many factors can contribute to a drilling or workover string getting stuck in the well. Some extra examples are borehole conditions, wellbore fluid properties, formation characteristics and assembly problems.
Vigor Free-Point Indicator Tool accurately determines the stuck point in pipe, tubing or a casing string. The real-time data allows the operator to make rapid and informed decisions in determining the next steps to recover the stuck downhole assembly.

Description
China Vigor Drilling Oil Tools And Equipment Co., Ltd. is one of the most professional manufacturers and suppliers of free-point indicator tools (vfpt) in China, featured by competitive price and fast delivery. Welcome to buy high quality free-point indicator tools (vfpt) in stock here from our factory.
When drill pipes or tubing are stuck in the well and stop regular activities, Vigor Free-point Indicator Tools (VFPT) can reduce the costly rig time for clients.
With single-trip operation, the Vigor Free-Point Indicator Tool can slightly magnetize the pipe or tubing during a run-in hole. When reaches the target position, then lift the pipe to measure the changes in the pipe's magnetic properties and store the data in our Memory Unit-MHWT43C.
After the collecting data, then proceed with the data with special software and differ out the free/stuck pipe position with a standard report.
features
-
Free-point Indicator Tools (VFPT) can efficiently achieve continuous measurement in drill pipe/tubing, and have high practicality when compared to traditional point measurement card instruments.
-
VFPT can quickly and accurately determine the stuck point position in a high-deviated or horizontal well through a single-trip logging process, suitable for high-strength alloy pipes and coated pipes.
- It adopts a fully isolated dual backup structure, which can safely and reliably complete each logging task.
- Wireline conveyed, coiled tubing conveyed or Sucker Rod conveyed to log in horizontal well.
- Easy to work in small hole well, no need to anchor in well during logging when compared to traditional free-point tool.

Components
1. Sensing Unit
It is the core component of the VFPT, responsible for detecting the free point of the stuck pipe, which typically consists of accelerometers or other vibration sensors that measure the movement and vibrations of the drill string.
2. Downhole Electronics
The downhole electronics include the processing unit, memory, and communication systems.
①The processing unit analyzes the data collected by the sensing unit and determines the location of the free point.
②The memory stores the collected data for later analysis and interpretation.
③ The communication system allows the transmission of data from the downhole tool to the surface, enabling real-time monitoring and decision-making.
3. The mechanical components of a VFPT include the housing, connectors, and other structural elements.
4. The VFPT requires a power source to operate the sensing unit, electronics, and communication systems.
5. The surface equipment includes the display unit, data acquisition system, and software.
①The display unit presents the data collected by the VFPT, allowing the drilling team to interpret the results and determine the location of the free point.
② The data acquisition system receives and processes the information transmitted from the downhole tool.
③ The software provides the necessary tools for data analysis, visualization, and decision-making.
Applications
1. Stuck Pipe Diagnosis
The primary application of Free-point Indicator Tools (VFPT) is to determine the location of a stuck pipe in the wellbore.
When the drill string becomes stuck, the VFPT is deployed to identify the free point, which is the point where the pipe is no longer moving freely.
This information helps the drilling team develop an effective strategy to recover the stuck pipe, minimizing the risk of costly and time-consuming fishing operations.
2. Casing and Tubing Evaluation
It can be used to assess the condition of casing and tubing strings in the wellbore. By detecting changes in the vibration patterns, the tool can identify potential issues such as casing deformation, parting, or collapse. This information allows the operators to take proactive measures to address these problems and maintain the well's integrity.
3. Wellbore Obstruction Detection
Free-point indicator tools can be employed to detect the presence of obstructions or restrictions within the wellbore.
4. Drilling Optimization
By monitoring the vibration patterns, the tool can provide insights into the drill string dynamics, which can be used to identify and mitigate issues such as excessive vibrations, stick-slip, or other drilling-related problems.
This information can lead to improved drilling parameters, enhanced wellbore stability, and increased overall drilling efficiency.
