That’s all it took to bring a coiled tubing operation to a full stop. During rig-up, ring gaskets were missed while making up the pressure control stack. At first, everything seemed fine. But as soon as we pressured up, we noticed fluid leaking back through the connections. No pressure integrity. The issue? Without ring gaskets—especially […]

Stabbing a TIW Valve is an essential operation in well control during drilling, particularly during tripping operations. The TIW valve is a type of back-pressure valve used to provide a barrier against pressure from the wellbore. Here’s a breakdown of the operation of stabbing a TIW valve: b. StabbingOnce a joint of drill pipe is […]

The wiper plug system is an essential component of well cementing operations. Installed on the cement head, these plugs ensure efficient displacement of cement into the casing by:Separating fluids (mud, spacer, cement, displacement fluid),Cleaning the casing interior, andPreventing contamination between fluids. Cementing Sequence Using Wiper Plungs 2.Cement Slurry:Pumped immediately after the bottom plug.Flows downhole behind […]

Is a common recovery method in oilfield drilling operations when a part of the drill string or tubular gets stuck or broken off in the wellbore. Here’s a breakdown of how it works and when it’s used: A taper tap is a fishing tool designed with a gradual external taper and hardened threads that can […]

A shale shaker is the first line of defense in the solids control system during drilling operations—especially critical when drilling with oil-based mud (OBM). Here’s a quick breakdown: Function:It removes large cuttings from the circulating drilling fluid (mud) before the mud is reused.Protects downstream equipment like desanders and desilters. With Oil-Based Mud:OBM is more expensive […]

SE Slip Type Elevator or Spider is a specialized tool used in oil and gas drilling operations for handling tubulars—especially casing, tubing, and drill pipe—safely and efficiently. What is the SE Slip Type Elevator or Spider?The SE Series Elevator/Spider is a combination tool that serves two purposes: This dual functionality allows it to run and […]

Christmas tree wellhead often just called a Christmas tree, is a vital piece of equipment in oil and gas production. It sits on top of a well and controls the flow of hydrocarbons after the well has been drilled and completed. Here’s a breakdown of its purpose and components: Despite the festive name, a Christmas […]

A casing power tong is a hydraulic tool used on drilling rigs to make up (tighten) or break out (loosen) the threaded connections of casing pipes during the casing phase of drilling operations. These tongs are essential for running casing into the wellbore efficiently and safely. They apply controlled torque to ensure proper connection of […]

In the oilfield, accurate fluid measurements are vital—and that’s where the mud balance plays a key role. Also known as a mud scale, the mud balance is a simple yet highly effective tool used to measure the density of drilling fluids. Despite its basic design, it remains one of the most trusted instruments on any […]

Well servicing operation involving a tubing pump assembly at an oil well. The brass-colored component in the foreground is likely a standing valve or traveling valve, both of which are critical in a sucker rod pumping system. These valves regulate fluid movement, preventing backflow and ensuring efficient oil production. Breakdown of What’s Happening:
