Abstract: A pulsation and acoustic energy reduction dampener for installation within well piping between a standpipe and a swivel includes a body formed from a union connection sub providing a threaded male connection at one end of the body and welded to a union connection nut providing a threaded female connection at the other end, each for connection to the well piping. A flow restriction orifice assembly is secured by welding or gluing within the union connection sub and includes a replaceable wear component such as an annular ceramic insert with a tapered or cylindrical interior through-hole.

Abstract: A pulsation dampener includes a body having an internal cavity and an opening providing fluid communication between the internal cavity and a fluid flow external to the body. A flexible diaphragm fitted with the diaphragm radial compression ring is held within the internal cavity, allowing for improved seal ability and enhanced service life of the diaphragm at allowing at least some fluid from the external fluid flow to enter the internal cavity through the opening based on a pressure of the external fluid flow, the flexible diaphragm or elements in contact with the fluid from the external fluid flow that has entered the internal cavity.

Abstract: To inhibit damage to or failure of the bladder within a bladder-type pulsation dampener, an internal passage of a bladder saver device carrying pumped fluid from the pulsation bleed plate mounted within the internal passage and movable between a first position in which the pulsated fluid flow is unencumbered by the bleed plate and a second position in which the pulsated fluid flow is restricted by the bleed plate.

Abstract: A pulsation dampening device includes a body having an upper connection end and a lower connection end, each connection end adapted to connect the body to connectors for a drill string pipe segment that are part of one of a top drive, a lower Kelly valve, a saver sub, drill string sub, a drill string pipe and a bottom hole assembly. Flow restriction is provided within an internal flow path extending axially through the body and is configured to reduce pumped fluid pressure pulses originating from an agitator within downhole tools. The flow restriction is provided by a combination of one or more orifice(s) restricting fluid flow within the internal flow path, optionally coupled with relief feature(s) gradually increasing or decreasing a cross-section of the internal flow path, or by an orifice device. Flow restriction operates unidirectionally or bidirectionally relative to predominant fluid flow in attenuating pressure pulses.

Abstract: Top repairable gas-charged pulsation dampener designs include one or both of a threaded cover for bladder replacement and a standardized bladder with a double convex, anti-extrusion bladder button. The threaded cover, which speeds up bladder replacement over bolt-on covers, preferably has a two-piece construction to reduce torsion on the bladder neck. The bladder design, which includes a double convex, anti-extrusion bladder button, facilitates use of the same bladder design in both top repairable and bottom repairable gas-charged pulsation dampeners.
