The Microwave-Drill [PDF]

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

Gas Diagnostics: To Drill or Not to Drill?

Canadian International Petroleum Conference, 2004
Abstract 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
