The production of a hole in a mechanical component is usually done by using a drill. Although drilling a hole appears to be a simple operation, the accurate drilling of a hole of the right size at the right location, can be difficult. A large number of tools and machines have been designed for the drilling of holes economically, accurately, and quickly,

Drill bit seismic: A drilling optimization tool
Computer Standards & Interfaces, 1998Abstract In recent years a new drilling optimization technique has emerged. Drill bit seismic uses the acoustic energy radiated by a working drill bit to provide time-to-depth and look-ahead information while drilling. This information, available in real time at the wellsite, significantly reduces uncertainty.

Drill wear monitoring in cortical bone drilling
Medical Engineering & Physics, 2015Medical drills are subject to intensive wear due to mechanical factors which occur during the bone drilling process, and potential thermal and chemical factors related to the sterilisation process. Intensive wear increases friction between the drill and the surrounding bone tissue, resulting in higher drilling temperatures and cutting forces. Therefore,

Exploration Drilling Campaigns - Optimized Drilling Performance using Drilling Consortium Management
SPE/IADC Drilling Conference and Exhibition, 2011Abstract Currently there are many smaller operators drilling on the Norwegian continental shelf. It is not an optimal use of resources to staff a complete drilling department in-house in all of these companies. For others, the drilling activity requires that wells are drilled in a discontinuous manner. Therefore, the drilling process can

DRILL TIP AND DRILLING TOOL HAVING A DRILL TIP
2010The invention relates to a drill tip (2) comprising a base body (6) having chip flutes (22A,B) and extending in the axial direction along an axis of rotation (8) and having at least two main cutting edges (14A,B) on the front face thereof extending outward in the radial direction to a cutting corner (16A,B).

Flexible Drill-Stem Drill Rigs
2016Flexible drill-stem technology spools a flexible conduit onto a take-up reel to rapidly lower and hoist bits, motors, and other tools in and out of the borehole. Such operations proceed quickly compared to using a jointed-pipe drilling rig because the connection time is eliminated during tripping.

Drilling Technology Development: Casing Drilling
2009The drilling technology has developed through changes and improvements of conventional drilling systems to today’s actively working and successful systems. Examples of major drilling technology advances that resulted from optimisation or innovative changes to specific elements of the system include: steerable mud motors, polycrystalline diamond compact
