IEEE Conference Record - Abstracts. 2002 IEEE International Conference on Plasma Science (Cat. No.02CH37340), 2002 We present a drilling method that is based on the phenomenon of local hot spot generation by near-field microwave radiation. The microwave drill is implemented by a coaxial near-field radiator fed by a conventional microwave source. The near-field radiator induces the microwave energy into a small volume in the drilled material under its surface, and a

Mining companies heavily rely on drill-core samples during exploration campaigns as they provide valuable geological information to target important ore accumulations. Traditional core logging techniques are time-consuming and subjective.

Gas Diagnostics: To Drill or Not to Drill?
Canadian International Petroleum Conference, 2004Abstract A very important but often difficult question to answer when dealing with gas reservoirs is: to drill or not to drill? Why are some gas pools only drilled at 2 wells/section and some drilled up to 16 wells/section? How do you decide whether downspacing will be beneficial? An accurate assessment of important

Effects of the drill flute number on drilling of a casted AZ91 magnesium alloy
Materials Testing, 2019This experimental study aims to reveal the effect of the drill flute number on the thrust force, tool wear, tool life, chip morphology, surface hardness and microstructure in the drilling of a cast AZ91 magnesium alloy.

Reducing Drilling Costs by Drilling Faster
Proceedings of SPE Annual Technical Conference and Exhibition, 1997Abstract A new synthetic-based Penetration Rate Enhancer designed as an environmentally acceptable alternative to terpenes is shown to be an effective treatment for increasing penetration rates by preventing or minimizing bit balling while drilling active shales prone to forming "gumbo".

Drilling Holes with the Bow-Drill
Technology and Culture, 1970miliar to most carpenters and joiners in Britain, which appears to corroborate the authors' analysis of the action of the ancient Egyptian stone-boring tool. Fitted preferably with a rosehead countersink bit, it is also used one-handed for countersinking. The rotation is started by tilting the brace, thus making use of the gravity couple similar to the

A Drilling Contractor's View of Underbalanced Drilling
Proceedings of IADC/SPE Drilling Conference, 2002Abstract This paper is not a technical discussion of under balanced drilling (UBD). Nor is it a filled with "tricks of the trade" advocating a better technical means of drilling wells using UBD. It is a discussion about the best method, from one drilling contractor's view, to execute a safe and productive UBD project.
