Drilling rig A drilling rig is a machine which creates holes in the ground. Drilling rigs can be massive structures housing equipment used to drill water wells‚ oil wells‚ or natural gas extraction wells‚ or they can be small enough to be moved manually by one person. They sample sub-surface mineral deposits‚ test rock‚ soil and groundwater physical properties‚ and also can be used to install sub-surface fabrications‚ such as underground utilities‚ instrumentation‚ tunnels or wells.

3.1 Drilling rigs and technologies 3.1.1 Introduction The term drilling indicates the whole complex of operations necessary to construct wells of circular section applying excavation techniques not requiring direct access by man. To drill a well it is necessary to carry out simultaneously the following actions: a) to overcome the resistance of the rock‚ crushing it into small particles measuring just a few mm; b) to remove the rock particles‚ while still acting on fresh material; c) to maintain

DRILLING FLUIDS The key to making the rotary drilling system work is the ability to circulate a fluid continuously down through the drill pipe‚ out through the bit nozzles and back to the surface. The drilling fluid can be air‚ foam (a combination of air and liquid or a liquid. Liquid drilling fluids are commonly called drilling mud. All drilling fluids‚ especially drilling mud‚ can have a wide range of chemical and physical properties. These properties are specifically designed for

DRILLING THEORY Principles of percussive drilling In percussive drilling‚ the energy required to break the rock is generated by a pneumatic or hydraulic rock drill. Machines of this kind build up a pressure which‚ on being released‚ drives the piston forward (Fig. 1). The piston strikes on the shank adaptor. The kinetic energy of the piston is converted into a stress wave which travels along the drill string to the rock. In order to obtain the best possible drilling economy the whole

The Rig Veda The Rig Veda is composed of many documents that were recovered by archeologists and are believed to be the oldest written texts to date. These documents give us insight into what the culture was like for these ancient Aryans of India.

Oil Drilling Have you ever seen an animal covered in sludge‚ helpless and weak? Offshore oil drilling is one of our world’s biggest concerns. Offshore oil drilling is the discovery of finding oil or gasoline resources underwater. Usually the oil is found off the coasts of each continent and can also be found in lakes and small seas. Drilling for oil provides the energy to make fuels for cars and other machinery. Many different platforms can be used for offshore oil drilling such as drill ships
