Well testing helps determine the reservoir’s capability to produce hydrocarbons—especially in reservoirs with high gas-to-oil ratio (GOR)—and provides data on:Reservoir pressure and temperaturePermeability and skin factorFluid composition and phase behaviorProductivity index and deliverabilityWellbore and reservoir behavior under dynamic conditions Challenges of High-Gas Content:Phase behavior: Gas expands rapidly when pressure drops, affecting flow measurements.Flow instability: High […]

A Glimpse into Subsurface Precision I recently came across a short but powerful visual demonstration that encapsulates the intensity and precision of gun perforation—a vital step in well completion. This process, often hidden thousands of feet below the surface, is essential for establishing communication between the wellbore and the hydrocarbon-bearing formation. In this video, we […]

A real-time example from the rig floor In this video, we see a situation that underscores the importance of pressure management and situational awareness during drilling operations—particularly when tripping pipe. From the very start of the video, it’s clear that something is not normal. The drill string appears to be pushed upwards, with the elevators […]

Is an important procedure used to verify the integrity and operational reliability of a casing cutter tool before it’s run into the wellbore. A casing cutter is used to cut through casing or liner strings, often during plug and abandonment (P&A) operations or wellbore sidetracking. Purpose of Pressure TestingThe primary goals of pressure testing a […]

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 […]
