Wells
Oil and gas wells are being drilled in almost every country in the world, on land, in marshes, and offshore. These wells are generally classified as two land exploration wells and development wells.
An exploration well or “wildcat” is one that is drilled primarily for the purpose of determining that oil or gas actually exists in a subsurface rock formation. It is only after a well is drilled into a formation that the presence of oil or gas can definitely be confirmed or denied to be present.
A development well is a well that is drilled after an exploration well has confirmed the presence of petroleum in the formation. Usually it takes several development wells to efficiently produce hydrocarbons from a formation.
A wildcat is a well drilled in an area where no oil or gas production exists. With present day exploration methods and equipment about one wildcat out of every nine proves to be productive although not necessary profitable.
A wellhead equipment is installed at the surface of the wellbore. A wellhead includes such equipment as the casing and tubing. Wellbore is a borehole drilled by a bit may have casing in it or may be open (i.e. uncased). (The University of Texas. Huston.1980).
