Patent CA-2544908-A1 (CA)
Inventor: FLOOD DALE A
IPC: B23K35/38
Filed: 2004-11-15
Abstract: A welding process for non-stainless steel workpieces (12) using GTAW equipment (20) and hydrogen containing shield gas on a first root pass is improved by using a shield gas delivery system comprising hoses or conduits (30) made of elastomeric material having a moisture permeability coefficient of less that 275, preferably less than 100, and using a tungsten electrode (22) composition comprising at least tungsten and lanthanum oxide, and preferably tungsten, lanthanum oxide, yttrium oxide and zirconium oxide. Preventing moisture permeation through the elastomeric hoses (30) delivering hydrogen containing shield gas eliminates expulsion of fused weld metal during second pass filler welding over the root pass weld. Electrode life is enhanced using the tungsten compounds.

Title: Method for interpreting seismic data using duplex waves
Inventor: GORNYAK ZYNOVIY
IPC: G01V1/00
Filed: 2004-08-18
Abstract: A Method for Interpreting Seismic Data Using Duplex Waves is described.  Whereas substantially horizontal boundaries are readily identified using conventional processing methods based on primary reflections, it has been difficult or impossible to use such methods for locating substantially vertical events or boundaries. The method of the present invention uses secondary reflections to locate substantially vertical events by gathering common source or receiver traces for processing. Wave fields of these gathers are continued downward to the level of the base boundary, then at each discrete depth level, a seismic image of sub-vertical events is formed. The downward-continued gathers correspond to the travel time of the wave from when it left the source or the receiver point, was reflected from the base boundary, and arrived to the corresponding point of the discrete level of wave-field continuation. In order to increase the noise tolerance of the resulting image of the target sub-vertical event - seismic images, obtained from the common source and receiver gathers, may also be summed together or stacked.
