20160130921 | DOWNHOLE PUMP SEATING NIPPLE WITH PERFORATIONS - A pump seating nipple for retaining a downhole pump assembly in a fixed position within a production tubing string has a generally cylindrical body defining a nipple bore for receiving the downhole pump assembly. The pump seating nipple attaches to the production tubing string. At the bottom end of the body, the nipple bore is open to the bore of the production tubing string. An upper portion of the body surface engages a pump assembly seating cup. The body has a lower skirt which defines openings which allow gas flow from the nipple bore into the casing annulus. | 05-12-2016 |
20160069167 | DOWNHOLE GAS RELEASE APPARATUS - The present invention provides for an apparatus for use with a traveling valve assembly of a downhole pump for releasing gas and thereby breaking gas locks. The apparatus comprises a piston slidably disposed within a cylindrical housing, the piston being driven by an attached plunger element. On the down stroke of the pump, the piston protrudes through end of the cylindrical housing engaging and opening the adjacent valve. On the up stroke of the pump, the piston retracts into the cylindrical housing, disengaging from | 03-10-2016 |
20150107823 | DOWNHOLE TOOL FOR OPENING A TRAVELLING VALVE ASSEMBLY OF A RECIPROCATING DOWNHOLE PUMP - A downhole tool for opening a travelling valve assembly of a downhole pump is disposed with the travelling valve assembly within a pump barrel, and includes a substantially cylindrical housing and a piston. The housing defines an axial bore extending from a bottom opening for fluid communication with the pump barrel, a radial port for fluid communication between the axial bore and the pump barrel, and a channel formed in the outer surface of the housing for fluid communication between the radial port and the travelling valve assembly. The piston occludes the axial bore above the radial port, and in response to an upward pressure exerted by a production fluid below the piston, slides upwardly within the axial bore to engage and open a valve member of the travelling valve assembly. | 04-23-2015 |
20150075637 | TRAVELING VALVE CAGE - A traveling valve for use with a downhole pump includes a cage shell, which at its lower end, has an integral internal shoulder that defines an axial opening. A retaining ring within the cage shell abuts the internal shoulder. An upper end of a bushing is attachable to a plunger while the lower end of the bushing is attached to the cage shell. The bushing and cage shell define a bore in fluid communication with the axial opening. An insert within the bore allows fluid to flow in the bore from below the insert to above the insert. A ball reciprocates in the bore so as to seat on the retaining ring when the fluid pressure within the bore above the ball exceeds the fluid pressure within below the ball, and to be restrained by the insert when the fluid pressure differential within the bore is reversed. | 03-19-2015 |
20130025846 | DOWNHOLE GAS RELEASE APPARATUS - The present invention provides for an apparatus for use with a traveling valve assembly of a downhole pump for releasing gas and thereby breaking gas locks. The apparatus comprises a piston slidably disposed within a cylindrical housing, the piston being driven by an attached plunger element. On the down stroke of the pump, the piston protrudes through end of the cylindrical housing engaging and opening the adjacent valve. On the up stroke of the pump, the piston retracts into the cylindrical housing, disengaging from the valve allowing it to close. Fluid flows along the outer surface of the apparatus by means of fluid ports connected by defined fluid passages. | 01-31-2013 |
