I recently came across a video of a roughneck working without a helmet, gloves, or coverall. Zero PPE. Zero safety. This raises an important question: how can anyone work without safety in such a high-risk environment like a drilling rig? -Safety culture isn’t just about wearing equipment – it’s about mindset. If someone is not […]

In modern drilling operations, two technologies play a critical role in helping us understand the wellbore and make smarter decisions: Measurement While Drilling (MWD) and Logging While Drilling (LWD). MWD (Measurement While Drilling):-Provides real-time drilling parameters such as inclination, azimuth, toolface orientation, and downhole pressure.-Helps the directional driller steer the wellbore accurately and safely.-Ensures continuous […]

Once drilling operations are complete, the next critical step is the well test. This is where we move from cutting rock to truly understanding the reservoir’s potential. Why Do We Test?-Reservoir Evaluation: Pressure, permeability, and productivity index.-Fluid Characterization: Oil, gas, or water – and their properties through PVT sampling.-Well Performance: How the well responds under […]

One of nature’s most fascinating phenomena — a spring where water continuously flows while flames burn from the same source. How is this possible?Deep underground, organic matter trapped in sedimentary rocks decomposes over millions of years, producing methane gas (CH₄). This gas migrates upward through fractures and porous layers until it escapes at the surface. […]

When we begin drilling an oil well, the first section (surface hole) is one of the most critical phases where vibration plays a major role. Why vibration occurs:At this stage, large-diameter bits are used, usually with long Bottom Hole Assemblies (BHAs). The bit interacts with hard and variable formations near the surface, while heavy drillstrings […]

On a drilling rig, shale shakers are the first line of defense in solids control. Sometimes we see overflow on the shakers, which simply means that the drilling fluid and cuttings coming from the wellbore are too much for the shakers to handle. Why does this happen?-High flow rate or pump strokes pushing too much […]
