Blowout preventers made from plastic infused with graphene, phosphorescent material, and/or other enhancing material. They include a sleeve that is inserted into a well pipe or other opening from which first fluid (such as petroleum or natural gas) is escaping, to stop it from escaping. The large end of a funnel id placed over the well pipe opening. The small end of the funnel is connected to a return pipe. A high pressure pipe (through which a second fluid flows) with a smaller diameter is inserted into the opening. The primary source of power for the apparatus is the pressure from the fluid escaping from the well pipe or other opening, which turns a turbine and propellers that push the device down into the opening to stop the fluid from escaping. If the pressure from the escaping fluid does not provide enough power itself, supplemental power may be used.

A jet pump assembly is adapted to be releasably attached to a tubular member of a tubular string in an oil well. The jet pump may be pumped out of the tubular string to the surface by a reverse flow of power fluid down the well between the tubular string and the casing of the well. Consequently the jet pump may be serviced or reconfigured to a direct pumping mode without the necessity of a wire line or other apparatus. An attachment tool is provided that attaches to a fishing neck on the jet pump and also includes a plurality of seal cups. The attachment tool includes a rod which is adapted to release a locking mechanism positioned in the jet pump.

The downhole electromagnetic pump includes a pumping chamber that is provided with a throughbore through which fluid may be pumped. An electrode arrangement is provided in order to produce an electro-hydro-dynamic force on fluids within the pump such that fluid may be pumped through the pump in a desired direction. A method of utilizing the downhole electromagnetic pump in order to pump fluids in a downhole environment is also provided.

A gas-oil separation plant (GOSP) is configured to process crude oil produced from a well. A production stream from the well operates at a first pressure. A processed crude oil stream from the GOSP flows to a multi-phase ejector. The multi-phase ejector induces flow of a production stream from the well in response to the flow of the processed crude oil stream.

A housing for a data tool extends from the carrier. The housing is in fluid communication with the intake for allowing wellbore fluid to be exposed to the data tool. The carrier is seatable in the body by flowing power fluid and the carrier into the first aperture. The carrier is retrievable from the body by flowing power fluid into the second aperture.

The well may be drilled and operated as a geothermal well using a hybrid approach where a heat transfer fluid is injected into a hot rock formation but is not removed, and heat is extracted using a closed loop method. The geothermal well is then evaluated for use as a carbon dioxide sequestration well. In other embodiments, the well is drilled as a carbon dioxide sequestration well and then evaluated for its potential for generating geothermal energy using a hybrid approach where supercritical carbon dioxide is injected into a hot rock formation but is not removed, and heat is extracted using a closed loop method. Both horizontal and vertical wells are disclosed, in sedimentary rocks and in basement granite.

Disclosed herein are various embodiments of methods and systems for drilling a wellbore into an oil or gas production zone to prevent formation damage in the reservoir using underbalanced or near-balanced drilling techniques, wherein a jet pump drilling assembly is used to create a vacuum around the drill bit. The design of this jet pump drilling assembly prevents the flow of all drilling/power fluid from entering a drill bit Only fluids from the reservoir are allowed to enter the drill bit. The assembly includes a barrier to ensure that no drilling/power fluid discharged from the jet pump located above the drill bit can flow back around to the jet pump jet pump suction ports located in the drill bit thus preventing any drilling/power fluid from ever contacting the drill bit.
