| A diverter assembly (502) used with a manifold of an oil or gas well is described. The diverter assembly (502) comprises a housing (504) having an internal passage (508) having first and second ports. The manifold has a choke body (500), which, in a first configuration, forms part of a first flowpath (10, 500, 530) to and from a bore of the manifold. The first port of the internal passage is connected to the choke body (500) and the second port of the internal passage is connected to a conduit to provide an alternative flowpath (10, 500, 520, 544) to/from a bore of the manifold via the diverter assembly (502). A method of diverting fluids is also described. | ||||||

| The system includes a number of flexible fluid containment structures, or tubes, for storing fluids used in or produced during fracking. The tubes may be filled to store water prior to introduction into the well or drilling waste expunged from the well. A series of valves and pumps control the flow of fluids to and from the tubes, well, and purification equipment. A backflow preventer including a primary port, forward port, and return port supports bi-directional fluid transfer with the well. Drilling fluids are piped into the forward port and exit the primary port to the well. A flow meter may be coupled to the forward port to determine the volume of fluid flowing through the forward port to the well. Drilling waste may also return from the well via the primary port and exit the return port, which may also include a flow meter. | ||||||

| An improved method and apparatus for dropping a ball, plug or dart during oil and gas well operations (e.g., cementing operations) employs a specially configured valving member with curved and flat portions that alternatively direct fluid flow through a bore or opening in the valving member via an inner channel or around the periphery of the valving member in an outer channel. In one embodiment, the ball(s), dart(s) or plug(s) are contained in a sliding sleeve that shifts position responsive to valve rotation. An optional indicator indicates to a user or operator that a ball or plug has passed a selected one of the valving members. | ||||||

| 226 | WELLHEAD SAFETY VALVE ASSEMBLY | EP15786205.3 | 2015-04-30 | EP3137726A1 | 2017-03-08 | Landry, Harold Wayne |
| A valve assembly is installed within a wellhead such as a conventional tubing hanger or casing hanger used to suspend pipe or other tubular goods in a well. A seal bushing assembly is installed in a tubing head assembly or other wellhead component. A hanger valve assembly is stung into the seal bushing assembly and includes a valve that can be selectively opened or closed. In the open position, the valve does not restrict a central flow path diameter through the hanger and wellhead. In the closed position, the valve contains pressure and/or fluid flow and fully seals against wellbore pressure acting on the valve. A wellhead adapter covers the hanger valve assembly and provides an attachment point for a conventional Christmas tree or other wellhead equipment. | ||||||

| An apparatus for assisting an actuator to close a valve has a cylindrical booster housing with a central axis. The booster housing includes an upward facing piston cavity and a downward facing lower cavity with internal threads for selectively coupling with external threads of a piston head of a valve actuator. A bulkhead is formed between the piston cavity and the lower cavity. The bulkhead has an opening for selectively accepting an actuator stem of the valve actuator therethrough. A booster piston is located within the piston cavity. The booster piston has a piston mounting means located on its bottom side for selectively securing a top end of the actuator stem of the valve actuator to the booster piston. The booster piston is moveable upwards in an axial direction to move the valve from a lower open position to an upper closed position. | ||||||

| 236 | At-surface tool for pulsed injection of liquids | EP10160752.1 | 2010-04-22 | EP2248992A3 | 2015-07-15 | Graham, Benjamin Eric; Masse, Andre Michael; Davidson, Brett Charles |
For pulsed injection of liquids into the ground, the tool has a rotating cylinder, having through-slots. The tool has an insert, which is pressed against the rotating cylinder. As the cylinder rotates, the slots in the rotor cover/uncover the slots in the insert, creating the required pulses. By suitably shaping the slots, the pulses can have a fast rise-time from closed to open. The insert is shaped to minimize flow interference.

A modular assembly for a wellhead has a housing and a plurality of modular cartridges. The housing connects with a studded or flanged connection to the wellhead, which can have a tubing adapter, casing hanger, etc. The modular cartridges can interchangeably stack in the housing's internal pocket so that the bores of the stacked cartridges configure the through-bore of the assembly communicating the wellhead with external components, such as flow lines, capillary lines, etc. The modular cartridges include a spacer cartridge, a hanger cartridge, a valve cartridge, and a cross cartridge. The spacer cartridge can be used to space other cartridges in the internal pocket, and the hanger cartridge can be used to support capillary strings and/or velocity strings in the wellhead. The valve cartridges have valve elements that can be opened and closed by bonnets that affix externally to the housing. The cross cartridge can have one or more cross ports to divert the assembly's through-bore to additional flow components, such as flow lines, wing valves, chokes, and the like.
