Geological drilling is an indispensable process for deep geothermal development, geological prospecting, and mineral exploration. The complex geological environments with high temperature, high pressure, and high terrestrial stress contribute to undesirable drilling faults, such as drillstring failures, which can compromise human safety and increase the asset cost [1], [2]. Jun 1, 2021 · Geological drilling is a complex industrial project to drill towards deep formation for purposes, such as geological prospecting and resources exploration. It is usually operating under complex geological conditions, which may lead to a high risk of downhole incidents and thus compromise the drilling efficiency [1].
The most common materials for well casing are carbon steel, plastic, and stainless steel. Local geology often dictates what type of casing can be used. Well Caps are placed on top of the well casing to prevent debris, insects, or small animals from getting into the well. Well caps are usually made of aluminum or plastic.Casing (borehole) Casing is a large diameter pipe that is assembled and inserted into a recently drilled section of a borehole. Similar to the bones of a spine protecting the spinal cord, casing is set inside the drilled borehole to protect and support the wellstream. The lower portion (and sometimes the entirety) is typically held in place ...
