166750130 | Well caps or casing heads | 9 |
20090159261 | Bird Bath Wellhead Cover - A device comprised of a basin forming a reservoir and a lip extending downward from the bottom surface of the basin and adapted to temporarily secure the device to a wellhead such that the device at least partly conceals the wellhead. In one embodiment, the device is a bird bath. | 06-25-2009 |
20130000885 | Pipe grapple - A grapple for controlling, monitoring and stopping the flow of oil, natural gas and the like from a broken, flanged pipe. A housing encloses a ring of material that is more ductile than the broken pipe flange. The force applied by a weight, presses a driving device against the broken pipe flange periphery, the force so applied distorts the ductile ring, thereby establishing a fluid-tight seal between the flange and the housing. | 01-03-2013 |
20130068447 | WELLHEAD ISOLATION TOOL AND WELLHEAD ASSEMBLY INCORPORATING THE SAME - A wellhead assembly is provided including a casing and a tubular member mounted over the casing. A flange extends from the tubular member. A generally elongated annular member is provided in the tubular member. The generally elongated annular member has a first end portion above the tubular member and second end portion below the first end portion. A hanger may be suspended within the tubular member. In such case, a seal may be formed between the elongate annular member and the hanger. | 03-21-2013 |
20130180703 | REMOVABLE ORIFICE PLATE DEVICE - A removable orifice plate device includes a body having an un-threaded portion which includes a groove. An orifice plate receiving slot bisects the groove and extends partially through a body diameter. An orifice plate having an orifice slides into the orifice plate receiving slot with an orifice central axis co-axially aligned with a longitudinal axis of the body at an orifice plate installed position in the orifice plate receiving slot. A tab integrally extends from the orifice plate and is oriented perpendicular to a body of the orifice plate. The tab includes an indicator symbol, the indicator symbol visually identifying a predetermined size of the orifice. A transparent indicator sleeve is slidably disposed on a body outer surface and is axially slidable between a first position covering the groove to a second position exposing the groove. The indicator symbol is visible through the indicator sleeve in the first position. | 07-18-2013 |
20140069630 | INTEGRATED WELLHEAD ASSEMBLY - An integrated wellhead assembly is provided to enable free flow production and artificial lift production from a well without requiring removal and/or reconfiguration of the wellhead assembly. The wellhead assembly includes an upper portion and a lower portion forming an integrated assembly. The upper portion includes a flow tee and at least one set of rams. The lower portion includes a shoulder to receive a hanger. The upper portion may seal the bore of the wellhead assembly and provide full bore access to the bore of the wellhead assembly. | 03-13-2014 |
20140110099 | MOLDED WELL HEAD COVER - A well head cover includes a polymeric body integrally including a tubular shaped main body portion. A tubular shaped mounting portion extends from the main body portion. A tubular shaped discharge portion is connected to the main body portion and is oppositely directed with respect to the mounting portion. A first discharge tube bore is created through a first end wall provided in the discharge portion. A second end wall is provided in the mounting portion. The second end wall has an end wall portion through which a second discharge tube bore is created. An axial centerline of the second discharge tube bore is coaxially aligned with an axial centerline of the first discharge tube bore. A pipe extending through the well head cover has a diameter adapted to provide a sliding fit with the first and second end walls at the first and second discharge tube bores. | 04-24-2014 |
20140216716 | Well cap assembly - A cap assembly for sealing the open end of a well casing or other pipe includes a top plate for mounting on the open end of the pipe, a bottom plate spaced apart from the top plate, an upper expansible gasket sandwiched between the top plate and an upper clamping plate, a lower expansible gasket sandwiched between the bottom plate and a lower clamping plate, spacer sleeves extending between the clamping plates, bolts through the bottom plate, both gaskets and clamping plates, the sleeves and the top plate, and nuts on the bolts. When the bolts are tightened on the nuts, the gaskets expand to seal the pipe at spaced apart locations. | 08-07-2014 |
20150345243 | Fluid Line Exit Block With Dual Metal-to-Metal Sealing - A termination block assembly for fluidly coupling a fluid line at a hydrocarbon production device includes a fluid line block with an inner surface selectively mated to a corresponding surface of the hydrocarbon production device. The fluid line block has a protruding member extending from the inner surface. A primary seal is located at an end of the protruding member. The primary seal has an inner diameter selectively circumscribing the fluid line extending from the hydrocarbon production device, and an outer diameter selectively engaging a sidewall passage surface of the hydrocarbon production device and sealing between the fluid line block and the hydrocarbon production device. A secondary seal circumscribes the protruding member, engaging both the inner surface of the fluid line block and the corresponding surface of the hydrocarbon production device and sealing between the fluid line block and the hydrocarbon production device. | 12-03-2015 |
20150376969 | REMOVABLE ORIFICE PLATE DEVICE - The present disclosure relates to a removable orifice plate device which has an orifice plate having a circular portion with an aperture therein, and a graspable end portion extending therefrom. A tee body is included which has oppositely extending first and second tee runs and a tee branch. The tee runs are coupled to gas inflow and outflow pipes. The tee body has internal structure forming a slot which is aligned with an opening formed by the tee branch, and which receives the circular portion of the orifice plate. The orifice plate, when installed in the slot in the tee body, thus allows a flow of fluid only through the aperture. A removable cover encloses the orifice plate within the tee body. | 12-31-2015 |
