Abstract: 1,257,506. Seismic energy generators. ESSO PRODUCTION RESEARCH CO. 13 June, 1969 [6 July, 1968], No. 30159/69. Heading H4D. [Also in Division F1] In a marine seismic source comprising an elastic sleeve 33 supported on two bell-shaped members 29, 43 and on a ring of spaced, parallel tubes 37 to define an expansible chamber, an explosive fluid is introduced into the chamber via a conduit 27 from a mixing chamber 25 and is ignited in the mixing chamber so that a high-velocity explosion wavefront travels down the conduit to promote rapid detonation of explosive fluid in the expansible chamber, and liquid condensate produced by the detonation of the explosive is removed from the chamber during operation of the source. A timer-controlled volume of the fluid (e.g. oxygen with propane or acetylene) is fed to chamber 25 by solenoid valves and ignited by spark plug 8. Combustion pressure inflates sleeve 33 to generate a seismic pulse and eventually opens a high inertia check valve to exhaust combustion products to atmosphere through vent 9. Cooling of residual combustion products by the flow of water between bellshaped members 29, 31 and in tubes 37 when the source is towed along produces a partial vacuum to draw sleeve 33 on to the tubes 37 to ready the source for further operation. A Venturi pump 51, supplied with high pressure liquid through line 1, scavenges condensed combustion products from inside the sleeve 33 at 62. The source may be actuated by means of a switch on a seismic wave recorder.
