Onshore oil drilling process

by Author
The drilling rigs are complexes of mobile equipment which can be moved (onshore and offshore) from one drill site to another, drilling a series of wells. In rotary drilling the rock is bored using a cutting tool called the bit, which is rotated and simultaneously forced against the rock at the bottom of the hole by a drill string consisting of hollow steel pipes of circular section screwed together. Offshore drilling is the process of extracting petroleum from reserves located beneath the Earth's oceans instead of reserves located on the mainland. Offshore oil rigs have developed greatly over the past years, and have become gigantic structures that house hundreds of people at a time.

Offshore well drilling is a process of drilling a hole in the ocean floor for extraction of natural resources. It is a challenging part of the exploration and development process that is carried out in several stages. Offshore drilling is a mechanical process where a wellbore is drilled below the seabed. It is typically carried out in order to explore for and subsequently extract petroleum which lies in rock formations beneath the seabed. Most commonly, the term is used to describe drilling activities on the continental shelf, though the term can also be applied to drilling in lakes, inshore waters and inland seas. Offshore drilling presents environmental challenges, both offshore and onshore from the produce The process begins by drilling to the bottom of a fresh water aquifer The drill is then retracted and pulls the loose rocks and sediment to the surface to be discarded (i.e., drilling muds). As drilling progresses, circulate mud through the pipe and out of the bit to float the rock cuttings out of the hole. Add new sections (joints) of drill pipes as the hole gets deeper. Remove (trip out) the drill pipe, collar and bit when the pre-set depth (anywhere from a few hundred to a couple-thousand feet) is reached.

The rig is sometimes referred to as the drilling package, particularly offshore. Spud-in-Date. To start the well drilling process by removing rock, dirt and other

There are two main types of onshore drilling. Percussion, or ‘cable tool’ drilling, consists of raising and dropping a heavy metal bit into the ground, effectively punching a hole down through the earth. Cable tool drilling is usually used for shallow, low pressure formations.
