Well Control Situations don’t send a calendar invite. They show up unannounced, and when they do – every second counts We see a suspected kick situation unfold during what appears to be a tripping operation. Fluid begins flowing from the annulus, indicating a possible influx into the wellbore. The flow is uncontrolled at first, a […]

Subsea Oil Leak
An oil spill leak under the ocean, especially from a subsea well, is a complex and hazardous event. Unlike surface spills, these leaks occur deep underwater, making them harder to detect, contain, and stop. Subsea Oil LeakIt’s an uncontrolled release of oil from a well, pipeline, or equipment located on the seabed—sometimes thousands of meters […]
Circulation Before a Cement Job
Circulation Before a Cement Job is a critical step in wellbore conditioning. It’s not just routine — it serves several key purposes to ensure the cement job is successful. Main Objectives of Circulation Before Cementing: Common Causes That Require Circulation Before Cementing:
High Vibration During Sliding
Captured this footage during a sliding operation on the rig. Vibration levels were noticeably high, even though we were expecting a smoother run. High vibration while sliding isn’t uncommon, but it’s always worth digging into the “why.” Some of the possible contributing factors we considered: We’re currently reviewing the downhole data (shock/vibe, RPM fluctuations, torque […]
Forgot the Ring Gaskets
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
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 […]
Wiper Plug on Cement Head – For Cement Displacement
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 […]
Fishing With A Taper Tap
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 […]
Shale Shaker While Drilling With OBM
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
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 […]
