2.7. GENERAL SAFETY
PROCEDURES
The following comments are applicable to both TCP and wireline conveyed
methods.
Additional comments are given in section specific to wireline conveyed
perforating.
a) All perforating operations, since they involve the handling and use
of explosives and possibly radioactive materials, require special safety procedures
to be strictly observed at all times.
b) Perforating operations...

perforation (5)(WIRELINE DEPTH CONTROL)
WIRELINE DEPTH CONTROL
Depth control for perforating is almost
universally obtained through radioactivity instruments run in the cased hole in
conjunction with the Casing Collar Locator (CCL). The Gamma Ray Log is
generally used (Figure B28) though, in some cases, the Neutron Log or both
Gamma Ray and Neutron are run. Accurate correlation...
Perforation (3) (Explosives Classifications)
Explosives Classifications
Explosives were invented
first by the Chinese in the 10th century, then independently by the Arabs in
the 13th century. The low explosive, or black powder, was characterized by slow
reaction rates, 500 to 1500 m/sec, and relatively low combustion pressure. Much
later, in 1846, the first high explosive was...
perforation(2) (Detonators)(guns)
Detonators
Perforating guns carry explosive charges to the borehole where they are
detonated creating cylindrical holes in the casing and the cement. This allows
oil and gas to flow from the formation into the well.
The critical parts of the perforating guns are:
