What are the different types of drilling rigs?

There are several types of drilling rigs, primarily categorized as rotary, percussion, and directional rigs. Rotary rigs, commonly used in oil and gas exploration, use a rotating drill bit to penetrate the earth. Percussion rigs, which use a hammering action to break rock, are typically employed for shallow drilling and mineral exploration. Directional rigs are specialized for drilling at various angles, allowing for access to resources that are not directly beneath the rig's location.
