Components Like Cementing Plugs That Simplify Complex Drilling Operational Process

An industry segment where the toughest of operating environments is witnessed is the oil and energy sector, especially drilling of wells. The most crucial element is proper planning and execution. Use of sophisticated equipment and accessories that precisely meet every operational challenge withstanding high pressure, temperature, depth, and other complexities is equally vital. Right from well cementation, lubrication of pipes, centralizers to surge reduction, friction reduction tools, float collar, and more, each component play an instrumental role in the operational success of any drilling project.

The working milieu of offshore and onshore rigs varies and so are requirements. There are various stages in the drilling process and each stage requires attention to detail besides use of sophisticated technology. Exactly meeting the technological requirements by using the right sophisticated equipment and accessories is critical to cementation. It is not a single component but every constituent, i.e. the complete package to address the overall cementation needs that matters. The equipment should withstand toughest of conditions such as high pressure and high temperature.

Two of the most essential components used during cementation operations for removal of drilling fluid are cementing plugs – top and bottom, providing positive wiping action. They come with molded wiper fins, surrounding the core. They help detach the cement slurry from other fluids. Mud gets dispersed and the casing inner diameter fills with mud sheath during drilling. These components help effectively remove the same, thus minimizing the contamination of cement besides maintaining predictable slurry performance. Use of the bottom component is important prior to cementing. It is initiated ahead of the cement slurry to reduce contamination by fluids inside the casing. It comes with a diaphragm, which bursts, allowing the cement slurry to pass through when it reaches the landing collar. After the cement is pumped, the top component goes operational. It mops cement from the inner diameter of the casing, facilitating displacement of the cement. Such is the complexity of the process! In short, besides shifting the cement, these components also clean the respective casing of any unwanted debris.

What about the use of thread lock compound during the cementation process? Risks are part of drilling; it is all about taking preventive and safety measures to avoid any interruption or disaster. During the drilling procedure, there are chances of accidental detaching of string components. This is avoided by the aforementioned additive. It substitutes welding for tubing and casing joints for prevention of accidental detaching of string components. There are various advantageous features of this additive. It can be mixed easily and has high lubricity. Its leak-proof seal is designed to withstand pressures. It can withstand continuous vibration and high break-out torque.
