Tripping operations in drilling are critical phases where the drill string is either pulled out of the well (tripping out) or run back into the well (tripping in). These operations require good planning and execution to maintain well control and prevent issues such as kicks or swabbing. This article outlines essential tripping considerations for effective tripping, focusing on trip tanks, slugs, pumping out, tripping-in techniques, and breaking circulation.
Slow Circulating Rates (SCRs) refer to the use of slow pump rates during circulation to manage wellbore pressure, especially during situations where there is a need to control or “kill” the well. SCRs are integral in maintaining stability and safety in drilling environments, as they help manage bottom hole pressure, mitigate friction in the annulus, and provide additional control over circulation pressures. Let’s delve deeper into why SCRs are essential, how they are applied, and the importance of accounting for friction pressures, particularly in subsea operations.
In this article, we will show you how to calculate weight of casing or conductor in lb/ft based on known value of pipe OD and ID. When working in drilling operations, accurately knowing the weight of the casing or conductor pipe is essential for ensuring safety and efficiency. This weight is typically measured in pounds per foot (lb/ft). While standard specifications provide this information, there are instances when you only have access to the pipe’s outer diameter (OD) and inner diameter (ID). In such cases, you can calculate the weight using a straightforward formula.
In oil and gas drilling operations, torque is a crucial factor in ensuring that drill pipes, casings, and other tubular components are securely connected. Makeup torque is the force applied to tighten the connection between two pipes, ensuring a proper seal and structural integrity during drilling. Understanding how to calculate and apply makeup torque is essential for maintaining safe and efficient operations, and rig tongs play a vital role in this process.
This article will explain how makeup torque is applied using a rig tong and provide a calculation example to illustrate the process. Continue reading
Well control responsibilities on a rig involve a coordinated effort by multiple personnel, each tasked with critical roles during well control operations. These responsibilities are vital in managing potential risks and ensuring that the well is controlled and stabilized effectively.
