Drilling rig and derrick (rig)
In exploration a drilling rig is a derrick (rig) that is suitable for the development of oil, gas or water deposits by means of deep drilling.
The main components of a derrick (rig) are:
- Steel tower
- Work platform
- Finger board (monkey board)
Derricks are classified as “top drive” or “rotary table drive” rigs.
Borehole -> exploration well, exploratory drilling
Exploration well, reconnaissance drilling and exploratory drilling refer to deep drilling in order to search for and investigate oil, gas and geothermal deposits.
Borehole -> deep drilling
Deep drilling refers to drilling into deep geological layers in order to develop oil, gas or warm water (geothermal) deposits.
Deep drilling of boreholes with a diameter of more than one meter is called large hole boring or shaft drilling.
Drilling process -> rotary
Vertical and slightly angled deep drilling to develop oil fields, gas deposits or hot water deposits is often performed using rotary drill pipe. The corresponding drilling technique is referred to as the “rotary drilling process”.
