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. Flow restriction is provided within an internal flow path extending axially through the body and is configured to reduce pumped fluid pressure pulses. The flow restriction is provided by a combination of one or more orifice(s) having sharp edges and 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. The flow restriction may operate unidirectionally or bidirectionally relative to predominant fluid flow direction in attenuating pressure pulses. Spacing between the orifice(s) and the relief feature(s) is based on a waveform of pulsation energy for pressure pulsations to be attenuated.

Abstract: A pulsation dampener (700, 800, 900) includes a quantity of liquid reactive fluid (e.g., about 20 gallons) contained within a flexible diaphragm (703, 803, 903) and separated from fluid from an external pumped fluid flow. The quantity of liquid reactive fluid is selected to dampen pressure pulses within the external pumped fluid flow. The pulsation dampener is configured to accommodate thermal expansion of the quantity of liquid reactive fluid by one or more of including a quantity of compressible foam (705) within the flexible diaphragm, allowing for a space (808) between the flexible diaphragm when holding the quantity of the liquid reactive fluid and a body of the pulsation dampener, or providing a reset pressure relief valve (906).

Abstract: Replaceable wear inserts (303, 305) of a material resisting abrasive wear due to particulates within pumped fluid are used for the inlet and/or outlet of a pulsation dampener (300) coupled to the outlet of a land-based or mobile-mounted pump (101). The wear inserts may be integrated with pressure orifice devices contributing to pressure pulsation dampening. The wear inserts may have internal passages or be mounted to create turbulent flow through the pulsation dampener to mitigate the risk of dead spots accumulating particulates. The wear inserts may be sized for either "loose" or "tight" fit within the inlet and outlet to facilitate removability despite the potential for particulates embedding within the gap. Grooves (714) may be provided with O rings to seal against pressure leaks.

Abstract: A cartridge shell (400) for a suction or discharge stabilizer dampening pumped fluid pressure pulsations at an inlet or outlet of a reciprocating pump (101) includes a head (401) including a protrusion, an annular shell (403) of deformable material of a deformable multi-ply material coupled to the protrusion, a plug (414) coupled to the annular shell of deformable material at an opposite end of the annular shell of deformable material from the protrusion, and a cellular foam (413) included within the interior of the annular shell of deformable material.

Abstract: A pulsation control device, coupled to a reciprocating pump with either suction or discharge piping, and having a spherical or cylindrical interior chamber that includes a curved baffle with a pressure drop device, e.g. a choke, separating the interior chamber into two volumes, is disclosed. The pulsation control device forces fluid flow through the pressure drop device, which provides an effective fluid passage that is smaller than the fluid passage for one or both of the inlet to and/or the outlet from the interior chamber. Fluid entering the pulsation control device reacts with fluid contained within the volume thereof on both sides of the baffle. The baffle attenuates pressure pulses within fluid passing through the interior chamber and improves acoustic pulsation energy reduction. The pressure drop device dampens high frequency pulsation magnitudes of pressure pulses within fluid passing through the interior chamber.

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: 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: 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.
