Abstract: A positive displacement wellbore servicing pump having a power end and a fluid end is disclosed. The fluid end has a main chamber and a suction bore in fluid connection with the main chamber and the suction bore has a suction central axis vector. A discharge bore is in fluid connection with the main chamber and the discharge bore has a discharge central axis vector. A portion of the suction central axis vector is vertically higher than any portion of the discharge central axis vector. A method of providing a wellbore servicing fluid to a wellbore is also disclosed. A method of providing a wellbore servicing fluid to a fluid end of a positive displacement pump is also disclosed.

Abstract: A threaded connection assembly comprises a nut, a multiplier connected to the nut via a first threaded interface having a first number of threads per inch and a well servicing pipe coupling connected to the multiplier via a second threaded interface having a second number of threads per inch. A method of forming a threaded connection for a well servicing application comprises forming a pipe coupling between two well servicing pipe sections and threading a connector to the pipe coupling to form a threaded connection without impact loading the connector. Another method for forming a threaded connection comprises disposing a first pipe section partially within a nut, threading a multiplier into the nut, threading the multiplier onto a second pipe section, and leveraging the multiplier against the nut, or vice versa.

Abstract: A suction valve for a positive displacement pump. Two springs are used to actuate a valve plug. A first spring has an uncompressed length greater than a distance between a spring retainer and the valve plug, providing a preload force closing the valve. A second spring has an uncompressed length less than the distance between the retainer and the plug, providing closing force to the plug only after a preselected valve lift. The first spring is relatively light and permits rapid opening of the valve to avoid cavitation. The second spring increases the effective spring constant when the valve is open to prevent flutter and to assist in closing of the valve upon commencement of a discharge pump stroke.

Abstract: According to one embodiment of the invention, a high-velocity fluid discharge device includes tubing having one or more orifices formed therein, a shroud coupled to the tubing such that, when a fluid flowing through the tubing exits the orifices, the fluid impinges on an inside surface of the shroud, and openings at both ends of the shroud. The openings have substantially the same areas.
