CEMENTING A WELLBORE USING A DIRECT INK PRINTING - A simplified explanation of the abstract
This abstract first appeared for US patent application 17551051 titled 'CEMENTING A WELLBORE USING A DIRECT INK PRINTING
Simplified Explanation
The patent application describes methods and systems for cementing a wellbore using a printing technique. The process involves creating a slurry with cement, water, a polymer-based additive, and a rheology modifying agent. This slurry is then mixed to form a printing ink. The ink, along with a printer, is introduced into the wellbore, and multiple layers of cement-based composite structure are printed to form a strong wellbore seal.
- The patent application introduces a new method for cementing wellbores using a printing technique.
- The slurry used in the process includes a cement-based matrix, water, a polymer-based additive, and a rheology modifying agent.
- The slurry is mixed to form a printing ink that can be easily applied using a printer.
- The ink and printer are introduced into the wellbore, and multiple layers of cement-based composite structure are printed to create a strong seal.
- This innovation offers a more efficient and precise way of cementing wellbores compared to traditional methods.
Potential Applications
This technology can be applied in various industries and scenarios, including:
- Oil and gas drilling: The printing technique can be used to create wellbore seals in oil and gas drilling operations, ensuring the integrity of the well and preventing leaks.
- Geothermal energy: Cementing wellbores in geothermal energy projects can be done more effectively using the printing technique, improving the overall efficiency and reliability of the system.
- Underground construction: The method can be utilized in the construction of underground structures, such as tunnels and mines, to create strong and durable seals.
Problems Solved
The patent application addresses several problems associated with traditional wellbore cementing methods, including:
- Inefficiency: Traditional cementing methods can be time-consuming and labor-intensive. The printing technique offers a more efficient and automated approach, reducing the time and effort required.
- Lack of precision: The printing technique allows for precise control over the placement of cement layers, ensuring a uniform and reliable wellbore seal.
- Waste reduction: The ability to mix the slurry into a printing ink reduces the amount of excess cement and materials that may be wasted during the cementing process.
Benefits
The innovation described in the patent application offers several benefits, including:
- Improved efficiency: The printing technique streamlines the cementing process, reducing the time and resources required.
- Enhanced precision: The ability to print multiple layers of cement allows for precise control over the wellbore seal, ensuring its integrity.
- Waste reduction: The use of a printing ink minimizes material waste, resulting in cost savings and environmental benefits.
Original Abstract Submitted
