Drilling in deep waters can be performed by two main types of mobile deepwater drilling rigs: drilling rigs and . Drilling can also be performed from a fixed-position installation such as a fixed platform, or a floating platform, such as a , a , or a semi-submersible production platform. 1. Fixed Platform – A Fixed Platform consists of a tall, (usually) steel structure that supports a de. [pdf]
Drilling is the process of cutting holes in a solid material using a rotating cutting tool. The indentation is a starting point for the drilling of the hole. Drilling is a cutting process in which a drill bit is used to cut or enlarge a hole in a solid material. .

1. Prepare the rock-drilling cavern, the specifications of which can be determined according to the method of drilling. Generally speaking, the height of the cavity is 2.6-2.8 meters when drilling a horizo. [pdf]
This requires use of 3,000-hp rigs due to heavy casing hookloads for the 24-in. and 18 5/8-in. cas-ings, high mud weights at relatively deep depths in 16-in. and 12 1⁄4-in. hole sec-tions, and fairly high torques throughout the well. [pdf]
To connect the drill bit with a drill rod you can use an adapter. It is included to kit with each drill bit. The adapter has a ready made thread for drill bit connection. On the other side you can make your thread for. [pdf]
A down-the-hole drill, usually called DTH by most professionals, is basically a jackhammer screwed on the bottom of a drill string. The fast hammer action breaks hard rock into small cuttings and dust that are evacuated by a fluid (air, water or drilling mud). The DTH hammer is one of the fastest ways to drill hard rock. The system is thought to have been invented independently by Stenuick. Origin of the nameDTH is short for “down-the-hole”. Since the DTH method was originally developed to drill large-diameter holes downwards in surface-drilling applications, its name originated from the fact that the percussion mechanis. .
In DTH drilling, the percussion mechanism – commonly called the hammer – is located directly above the drill bit. The drill pipes transmit the necessary feed force and rotation to the hammer and the bit, along with the flui. [pdf]

DTH is short for “down-the-hole”. Since the DTH method was originally developed to drill large-diameter holes downwards in surface-drilling applications, its name originated from the fact that the percussion mechanism followed the bit down into the hole. Applications were later found for the DTH method underground, where the direction of drilling is generally upwards instead of downwards. [pdf]
