Let’s look at what happens when formation pressure is greater than mud pressure, shall we?When drilling penetrates a formation, that formation may contain fluids under pressure.If the pressure from the mud column (hydrostatic pressure) is lower than the formation pressure, formation fluids can enter the wellbore.This is called a kick. Let me give a little […]

When we drill… we create problems. Why? Because Drilling creates a wellbore…, But it also creates risk. When the drill bit cuts through rock:Heat is generatedRock cuttings accumulateFormation pressures are encounteredThe wellbore can become unstable So what keeps the operation controlled? The Drilling fluid commonly called drilling mud. What is a Drilling Fluid? Drilling fluid […]

Before we talk about drilling mud, we must first understand drilling itself. Drilling is the process of creating a wellbore in the earth’s subsurface formations to safely access hydrocarbon reservoirs. In simple terms, drilling is how we create a controlled pathway from the surface down to oil and gas-bearing formations. During drilling: Drilling is important […]

Running casing is one of the most critical operations in drilling — ensuring well integrity, zonal isolation, and long-term production safety. Here’s a clear breakdown of how it’s done using a CRT (Casing Running Tool): Key Safety Notes• Always monitor torque & drag trends• Avoid over-torqueing connections• Maintain proper communication between rig floor & driller• […]

A serious reminder from coiled tubing operations: when a kick reaches surface, surface equipment instantly becomes part of the well control battle. During this coiled tubing intervention, gas flowed through the coil outlet while the tubing was being reeled in under active kick conditions. At that stage, injector control became critical because uncontrolled tubing movement […]

Core barrel operation is where drilling meets geology in its most valuable form During coring, the core barrel is run into the wellbore to cut and recover a cylindrical section of formation rock without destroying its natural structure. This allows geologists and drilling engineers to directly study lithology, porosity, permeability, fractures, fluid content, and reservoir […]
