Abstract
A system and method of damping fluid pressure waves in a subterranean well. In a described embodiment, pressure waves are damped by positioning a dampener in the well during a perforating operation. The dampener may attenuate the pressure waves by absorbing the pressure waves, flowing the pressure waves through viscously damping material, generating complementary pressure waves, changing a material phase, or by a combination of these methods.
Claims117
A perforating system for a subterranean well, comprising:
- a perforating gun positioned in the well;
- and
- a fluid pressure wave dampener positioned in the well, the dampener damping pressure waves generated by detonation of the perforating gun.
A method of damping pressure waves in a subterranean well, the method comprising the steps of:
- providing a fluid pressure wave dampener;
- positioning the dampener in the well;
- generating the pressure waves in the well;
- and
- damping the pressure waves with the dampener.
