Coal Mining

Responsible, cost effective mining of coal requires innovative technical solutions suitable for the complex geological, reservoir and operational challenges encountered in underground and surface coal mines.

Founded in 1999 in Wyoming, USA, the “Saudi Arabia of coal”, WellDog has pioneered geochemical understanding of coal using its coal reservoir simulation laboratory and patented downhole reservoir analysis systems.

Our services are designed to assist mining operations in controlling the reservoir and geological conditions that affect gas drainage, ventilation, and outburst.
