The present invention is directed to methods and apparatus to construct subsea wells with redundant parallel fluid flow control systems to allow new methods to stop subsea blow outs. More specifically, this invention provides methods and apparatus to construct subsea wells with a plurality of redundant parallel paths allowing for the first time drill pipe and other intervention conduits, wire line, and fluids to be deployed below a damaged drilling riser and or a damaged blow out preventer through a separate blow out preventer and riser system presented in this invention.

Method and apparatus to control fluid flow from subsea wells

The present invention provides methods and apparatuses for the enhanced recovery of fluids from subterranean reservoirs using cryogenic fluids. Using the Earth's geothermal energy to warm cryogenic flood fluids injected into subterranean reservoirs, the pressure within the subterranean reservoir is increased. Consequently, the reservoir conductivity is enhanced due to thermal cracking, and improved sweep efficiency of the reservoir by the flood fluids is provided. This rise in pressure due to the injection of the cryogenic fluid increases the reservoir conductivity enhancement and improves sweep efficiency of the flood fluids, which leads to the production of more fluids from to the subterranean reservoirs.

The present disclosure provides an engine assembly that is installed below the surface of the earth to harvest the thermal energy of the earth, using a working fluid in a closed loop system, and convert it into electricity, which can be commercialized at the surface. The subterranean engine comprises a hot region and a cold region, and a working fluid that moves between the two regions. The movement and efficiency of the working fluid operates the pistons that drive a generator coupled to the pistons, thereby generating electricity. The hot region of the engine is primarily powered by the geothermal energy. The engine can further incorporate renewable energy to improve the movement of the working fluid between the hot and cold regions. The system can further be used to store renewable energy below ground.

A method and apparatus for the enhanced recovery of hydrocarbon fluids from subterranean reservoirs using cryogenic fluids. Using the Earth's geothermal energy to warm cryogenic flood fluids injected into subterranean reservoirs, the pressure within the subterranean reservoir is increased. This rise in pressure due to the injection of the cryogenic fluid leads to the production of fluids from to the subterranean reservoirs.

The invention relates to methods and apparatuses for the subterranean injection of reactive substances like propellants into wellbores and subterranean reservoirs. These methods and apparatuses controls the temperature of a reactive substance for safe handling at surface and controls the decomposition rate of the substances in the subterranean environment. In addition, these methods and apparatuses provide a means for safe dilution of reactive fluids in the event of a leak or spillage of the reactive substance.

The application discloses a safety valve including a flapper valve and a packer assembly to be installed in a bore to isolate a first zone from a second zone. Preferably, the safety valve includes a hydraulic conduit bypassing the flapper valve to allow communication therethrough when the valve is closed. Furthermore, the safety valve preferably allows unobstructed passage of tools and fluids therethrough when the flapper valve is open. The application discloses a method to install a safety valve in an existing string of tubing by deploying a packer assembly having an integral safety valve.
