Abstract: A fluid delivery system including at least a housing for a charge-free pulsation dampener of a type utilizing elastomeric compression material, but without the compression material therein, includes a system pulsation dampener. The fluid delivery system includes a fluid reservoir, a fluid pump, a manifold, a pulsation dampener, and piping. The fluid reservoir stores a fluid used for a drilling procedure. The fluid pump pumps the fluid from the fluid reservoir through the fluid delivery system. The manifold is located downstream from the fluid pump, and receives and combines fluids from the at least one fluid pump. The pulsation dampener receives the combined fluid from the manifold, and dampens residual pulsations from the manifold. The piping receives fluid output from the pulsation dampener, and transfers the fluid received from the pulsation dampener further downstream.

Optionally, a mini-dampener may be coupled between each pump and the system pulsation dampener. A single header pipe may carry combined flow from the at least two pumps into the system pulsation dampener, or separate header pipes may carry individual flows from the pumps into the system pulsation dampener.

Each of the first, second, and third gas cartridges independently and cumulatively reduce pulsations entering the cylinder. A diameter of the third gas cartridge is less than a diameter of the second gas cartridge, which both are less than a diameter of a first gas cartridge.

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: Replaceable wear inserts of a material resisting abrasive wear due to particulates within pumped fluid are used for the inlet and/or outlet of a pulsation dampener coupled to the outlet of a land-base or mobile-mounted pump. 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 may be provided with O rings to seal against pressure leaks.

From the wye, a first flow path increases pump pressure of the fluid and a second flow path allows the fluid to flow unrestricted. Piping receives the fluid from the first flow path and the second flow path and discharges the fluid further downstream.
