Casing drilling, otherwise known as drilling with casing (DwC) or casing while drilling (CwD) is an alternative drilling technique to the conventional drilling method. Casing drilling involves the simultaneous drilling and casing of well with a (active-standard) casing string. It is mandatory to note that casing is the same grade and weight as in

6.2.1 Drilling and blasting DRILLING PATTERN DESIGN The drilling pattern ensures the distribution of the explosive in the rock and desired blasting result. Several factors must be taken into account when designing the drilling pattern: rock drillability and blastability, the type of explosives, blast vibration restrictions and accuracy

Blasting trials in the 1.6 metre high stope had indicated a three row drilling pattern with the centre row staggered, and a spacing of one metre between holes in any one row. Blasting using cordtex and Magnum cartridges was very successful, leaving full barrels along the stope. With limited blasting it was difficult evaluate rock throw.

The performance standards require that the abrasives shall not contain more than 1 % by weight material passing a #70 U.S. standard sieve before blasting, and . that . after blasting the abrasives shall not contain more than 1.8% by weight material 5 microns or smaller.

blasting of cornices increases efficiency, boring holes along the presumed tension line exposes the ava-lanche blaster to considerable danger. Safety in borehole blasting depends critically on: 1. The blasting crews ability to judge correctly the safe working line. techniques for working with this high explosive (See Chapter 5 - Detonating Cord).

Drilling engineering is divided into several specialties which described in Fig. 1 Figure 1: Basic Knowledge of Drilling Engineering (Bourgoyne, 1986) Each part of the drilling knowledge is connected each other in the flow path of drilling design and operation. of the process. Figure 2: Flow path of drilling design and operation (Adams, 1985)

The drilling length is a significant parameter in horizontal borehole path design and drilling-state monitoring. It can be used for fitting the drilling profile, computing the deviation, designing the drilling profile, and developing an algorithm for automated directional drilling [3]. In addition,

The top drive device is a new type of oil drilling equitltiidthtditiltipment, revolutionized the traditional rotary table—Kelly stem drilling model, the drilling power (AC and DC motor or hydraulic motor) from the rig floor rotary table directly to the swivel, drilling string driven by the top directly.

resources are economically undrillable using conventional drilling methods. Managed Pressure Drilling (MPD) is a new technology that uses tools similar to those of underbalanced drilling to better control pressure variations while drilling a well. The aim of MPD is to improve the drillability of a well by alleviating drilling issues that can arise.

Dual Gradient Drilling (DGD) is a variation and a subset of Managed Pressure Drilling (MPD). Managed Pressure Drilling is a drilling tool that is intended to resolve chronic drilling problems contributing to non-productive time. These problems include: Well Stability Stuck Pipe Lost Circulation Well Control Incidents

In conventional drilling, the role of drill bit is very crucial. Most of the drilling improvements are in the form of proper design and selection of drill bit parameters. In some of the non-conventional drilling processes like laser drilling, electron beam drilling drill bits are never used. The mutually perpendicular
