In the world of drilling and well completion, the term "make up" carries a surprisingly wide range of meanings. While seemingly simple, it often encompasses crucial tasks that contribute to the smooth operation and success of a well project. Let's delve into the different ways "make up" is used:
1. Assembling and Joining: Building the Foundation
The most common meaning of "make up" in drilling is to assemble and join parts to form a complete unit. This can be seen in various scenarios:
2. Threading and Tightening: Ensuring Secure Connections
Another key aspect of "make up" involves screwing together two threaded pieces. This is a meticulous process often requiring specialized equipment and procedures:
3. Mixing and Preparing: The Art of Formulation
In certain contexts, "make up" refers to mixing or preparing a substance for a specific purpose.
4. Compensating for Delays: Staying on Schedule
Finally, "make up" can also mean compensating for lost time or deficiencies.
Breakout vs. Make Up: The Inverse
In contrast to "make up," which signifies assembly and connection, "breakout" involves disassembling and separating parts. This is crucial during dismantling operations, retrieving equipment from the wellbore, and preparing for the next stage of work.
Conclusion
The term "make up" is integral to the language of drilling and well completion, representing a diverse set of actions and procedures that are essential for successful well operations. Understanding the various meanings of "make up" is crucial for communication and ensuring a smooth and efficient workflow in the oil and gas industry.

This document expands on the multifaceted term "make up" within the context of drilling and well completion, breaking down the concept into key areas.
Chapter 1: Techniques of Make Up
The term "make up," in drilling and well completion, encompasses a variety of techniques centered around assembly, connection, and preparation. These techniques often require specialized tools and expertise to ensure safety and efficiency.
1.1 Mechanical Joining: This involves physically connecting components, primarily using threaded connections. This requires careful alignment to prevent cross-threading and ensure a secure, leak-proof seal. Torque management is critical to avoid damage to the threads or over-tightening. Techniques include the use of make-up tongs (manual or power operated), torque wrenches, and hydraulic power units for larger components like casing. Lubricants are often employed to facilitate connection and reduce friction.
1.2 Hydraulic Make Up: In some instances, hydraulic pressure is utilized for making up connections, particularly in challenging downhole environments. This method is employed for components like packers or specialized tools where precise control and pressure are needed for a secure connection.
1.3 Chemical Mixing: "Make up" also refers to the precise mixing of various substances, such as drilling muds and cement slurries. This requires precise measurements and consistent mixing to ensure the desired properties are achieved. Specialized equipment, like mud tanks and cement mixers, is used to achieve homogenous mixtures, which are crucial for successful well operations. The techniques used in mixing depend on the specific substance (e.g., high-shear mixing for cement, low-shear mixing for some mud components). Strict adherence to specified weight and volume ratios is paramount.
1.4 Compensatory Techniques: When addressing lost time or deficiencies, "make up" implies implementing strategies to overcome setbacks. This could involve adjusting drilling parameters, employing advanced drilling techniques, or adding extra casing or other components to compensate for weaknesses. These techniques are often situation-specific and require careful assessment to ensure that corrective actions are both effective and safe.
Chapter 2: Models and Procedures for Make Up
Several models and procedures guide the make-up process, ensuring safety and efficiency. These models often incorporate industry best practices and standards, ensuring consistent and reliable results.
2.1 Torque and Make-Up Procedures: Detailed procedures define the torque values and make-up sequences for different components, ensuring that connections are made safely and effectively. These procedures often incorporate safety measures such as the use of torque wrenches and monitoring equipment to prevent over-tightening or damage to components.
2.2 Mud and Cement Mixing Models: Mathematical models are employed to predict the optimal composition and properties of drilling muds and cement slurries. These models use variables like density, viscosity, and fluid loss to achieve the desired performance characteristics.
2.3 Risk Assessment Models: Before any make-up operation, risk assessment models help identify potential hazards and develop mitigation plans. This ensures that appropriate safety precautions are implemented to prevent accidents and ensure personnel safety.
Chapter 3: Software and Technology in Make Up
Modern technology plays a vital role in optimizing and improving make-up procedures.
3.1 Torque Management Software: Software programs monitor torque values during make-up operations, providing real-time feedback and alerts to prevent over-tightening or other issues.
3.2 Mud and Cement Modeling Software: Software packages simulate the behavior of drilling muds and cement slurries, aiding in the design of optimal mixtures.
3.3 Data Acquisition and Analysis Systems: These systems collect and analyze data from various sensors during make-up procedures, providing valuable information for improving efficiency and safety.
Chapter 4: Best Practices for Make Up
Adhering to best practices is crucial for the success and safety of make-up operations.
4.1 Proper Tool Selection: Choosing the right tools for the job is essential. This includes selecting the appropriate tongs, wrenches, and other equipment based on the size and type of components being connected.
4.2 Rigorous Inspection: Components should be thoroughly inspected before make-up to identify any defects or damage.
4.3 Adherence to Procedures: Following established procedures and guidelines precisely is paramount to prevent errors and ensure a successful outcome.
