Abstract: The invention relates to a method and an arrangement for igniting a gas flow by means of remote control. The aim of the invention is to maintain the current consumption so low that an integratable voltage source can be used. To this end, a thermoelectric safety pilot valve (17) is opened and the escaping gas ignited by the actuation of an electronic control unit (5) fed by a voltage source. Said thermoelectric safety pilot valve (17) is maintained open by a safety pilot magnet (18) by means of a holding current from the voltage source until a thermocouple (22) provides the required holding current once the gas flow has been ignited or a defined holding time is exceeded.

Title: Compositions and methods of cementing in subterranean formations using a swelling agent to inhibit the influx of water into a cement slurry
Inventor: CREEL PRENTICE G
IPC: E21B33/13
Filed: 2003-12-18
Granted: 2010-05-11
Abstract: Methods of cementing in subterranean formations, cement compositions, and methods for making the compositions are provided. A cement slurry is passed into a subterranean formation, and a swelling agent is passed into the subterranean formation to reduce an amount of water flowing into the cement slurry. The swelling agent may be combined with a carrier fluid before being displaced into the subterranean formation. Alternatively, the swelling agent may be pre-mixed with the cement slurry to form a new cement composition, followed by displacing the cement composition into the subterranean formation.  The swelling agent is present in an amount effective to, upon absorption of water and swelling to form a gel mass, substantially block the flow path of the water into the cement composition or reduce losses to low pore pressure intervals, thereby preventing the integrity of the cement composition from being compromised or lost to voidage, fractures, fissures, etc.
