Title: Sub-surface coalbed methane well enhancement through rapid oxidation
Inventor: OLSEN TOM
IPC: E21B43/27
Filed: 2007-04-03
Abstract: Methods of stimulating production of coalbed methane from a coal-bearing formation are described, one method involving providing a perforation charge comprising a standard charge portion and a charge additive able to produce localized temporary oxidizing environments in perforations; perforating a coal-bearing formation with the perforation charge to form initial perforations defined by carbonaceous material, the initial perforations having localized temporary oxidizing environments in them, and initiating combustion of the carbonaceous material using the oxidizing environments, thus enlarging the initial perforations. Other methods involve perforating the coal-bearing formation with a standard perforation charge, thereby creating perforations; and treating the perforations with a composition creating temporary local oxidizing environments involving an oxidant in the perforations, and initiating combustion of carbonaceous material using the excess oxidant, thus enlarging the perforations.

Patent CA-2587605-A1 (CA)
Inventor: LEE JEONG-WOO
IPC: H04B1/04
Filed: 2005-11-18
Abstract: A wireless receiver and a wireless receiving method are provided wherein a frequency of a radio frequency (RF) is down-converted into a frequency of a substantially zero intermediate frequency (IF) signal or a substantially low IF signal. The down-converted signal may be filtered by an integrated filter having a low quality factor and then up-converted again into a particular IF  signal, thereby integrating an external element. For example, a receiving device may receive a RF signal in a required band. A frequency down-converting device may down-convert a frequency so that a center frequency of the RF  signal becomes zero. A channel select filtering device may select a required channel from the signals whose frequency is down-converted. An IF signal converting device may up-convert a frequency of the channel selected signal into a required IF. An IF processing device may extract a baseband signal after the converted IF signal is inputted and processed. An amplifying device may amplify a signal with a gain required in a process of converting a frequency.
