Seismic prospecting explosive

DuPont s Pyrocore. See Ref 7, p9 DuPont s Seismic Prospecting Explosives, such as Seismograph 60% High Velocity" Gelatin Nitramons WW, WW-EL, S Sc S-EL Seismogel A Seismex and Seismex PW (Ref... [Pg.467]

Figure 14.10 illustrates the method of seismic prospecting on land by what is known as reflection shooting. A hole usually 10 to 12 cm in diameter is drilled to a depth of 15 to 30 m. The charge of explosive is likely to be 5 to 12-5 kg and the stemming used is usually water. As the explosive must fire under a depth of water which may exceed 45 m, special varieties of gelatines are employed (see p. 53). Alternatively, a powder explosive can be sealed into pressure-resistant metal containers. Special detonators are also employed, not only to withstand the possible head of water, but also to have a specially short bursting time (see p. 113). [Pg.149]

Seismograph-Grade Explosives for use in seismic prospecting on land and offshore. Various grades are available in diameters from 2 to 8 inches packaged in fiber cartridges, metal cans, or plastic ... [Pg.69]

Tutamite. One of the Italian Esplosivi per prospezioni geosismiche (Explosives for Geo-seismic Prospecting) is listed by Belgrano (Ref 31, p 334) together with other Italian seismic expls Sismite and Geo-Mon A, without giving their compositions... [Pg.445]

Principal applications of Detasheet expls include field demolition, underwater explosions, seismic prospecting and metal cutting and hardening. For example, manganese (Hadfield) steel can be hardened by inducing a shock wave in the metal thru detonation of Detasheet placed direcdy on the metal s surface (Ref 5, p 5)... [Pg.523]

Trade name of a sensitized gelatinous special explosive distributed in Germany and exported by WASAGCHEMIE. It is used for seismic prospecting and mud capping. [Pg.205]

PETN is one of the most powerful and most brisant explosives, its -> Stability is satisfactory, and its -+ Sensitivity is not extreme. It is used in high-efficiency blasting-cap fillings and detonation cords. If phleg-matized with a small amount of wax and pressed, it may be used to produce boosters and fillings for smaller caliber projectiles. PETN can also be incorporated into gelatinous, industrial explosives (e.g., for seismic prospecting). [Pg.314]

Trade name of explosives in layflat charges used in seismic prospecting for surface shooting in combination with Dynacord. Both products are manufactured and distributed by DYNAMIT NOBEL, Troisdorf, Germany. [Pg.343]

Seismic explosives produce the pressure impact during seismic measurements, which are carried out in prospecting for geological deposits, particularly oil horizons. Such explosives must detonate even under high hydrostatic pressures. [Pg.341]

Explosives in seismic thumpers which generate regular, highly controlled signals for petroleum prospecting. [Pg.70]
