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
Calibrate wireline & LWD logs
Reduce uncertainty in reservoir models

Types of coring:

• Conventional coring – highest quality, highest cost
• Sidewall coring – faster, targeted depths
• Rotary sidewall coring – modern, improved recovery

In an era of advanced logging and AI, cores remain the ground truth.
If you want to understand the reservoir — you must touch the rock.
