Core Samples: The Truth Inside the Rock 🪨🛢️ In drilling, nothing tells the real story of the reservoir like a core sample. While logs and seismic interpret, cores prove. A core sample is a cylindrical section of rock cut directly from the formation, preserving its lithology, porosity, fractures, and fluids exactly as they exist underground. Why cores matter: 🔹 Identify lithology and depositional environment 🔹 Measure porosity & permeability directly 🔹 Detect natural fractures and vugs 🔹 Ca
