William H Dragoset Jr, Dennis L Cumro: Method for determining the far-field signature of an air gun array. Western Geophysical Co of America, William A Knox, E Eugene Thigpen, April 14, 1987: US04658384 (20 worldwide citation)

The far-field pressure signature of an air-gun array is derived from near-field measurements. An array of air guns is deployed in the water at a desired depth. A hydrophone is suspended in the middle of the array at the same depth so that the guns are equidistant from the hydrophone. The lateral spa ...

Nicholas J Arend: Wireline cable head for use in coiled tubing operations. Western Atlas International, E Eugene Thigpen, February 28, 1995: US05392851 (19 worldwide citation)

The invention is a wireline cable head adapted to be used on a wireline tool string which is conveyed into a wellbore by a coiled tubing. The cable head comprises a biased, piston-type check valve which enables fluid circulation from the tubing into the wellbore, but prevents fluid flow from the wel ...
