Displacement mud refers to the drilling fluid that is used to replace or “displace” another fluid already in the wellbore. This is often done while running in hole with tools, casing, or liners. When Is It Used During RIH?Running casing or liners: When casing is run into the well, especially to total depth (TD), a […]

What happened:During a cementing operation, the flow line (used to direct returns from the wellbore to the shaker or pit system) became packed off—essentially blocked or restricted. As a result, returns had nowhere to go, and the cement being pumped had to find an alternate path. With no outlet, it flowed up through the BOP […]

Artificial lift is a method used in oil and gas wells to bring fluids (like oil, gas, or water) to the surface when the natural pressure underground isn’t strong enough to do it on its own. After some time, the natural pressure in a well drops. When that happens, the oil slows down or stops […]

It’s early mornings and late nights.It’s steel-toed boots, calloused hands, and backs sore from putting in real work.It’s missing birthdays, holidays, and moments you don’t get back. But we keep going… Out here, you learn real fast that nothing comes easy.The weather doesn’t care if you’re tired.The job won’t wait if you’re having a bad […]

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 […]

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 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:

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 […]

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 […]
