Safety valves and methods of using safety valves. The safety valve is provided to a wellbore having a hydrostatic pressure. The safety valve is configured to operate at tubing well pressure. Pressure is applied to the safety valve with a single control line. The safety valve uses an accumulator in fluidic communication with the control line such that pressure acting on the accumulator is fluidically connected to pressure in the control line. The safety valve is insensitive to the hydrostatic pressure.

Provided is a flow control valve, a well system, and a method. The flow control valve, in one aspect, includes a tubular configured to be positioned downhole in a wellbore, the tubular having a central longitudinal axis, and a piston located in the tubular, the piston configured to separate injection fluid located within the tubular from a working fluid located in a sealed working fluid chamber. The flow control valve, according to this aspect, further includes a valve assembly located within the tubular and coupled with the piston, wherein the piston is configured to axially slide within the tubular to move the valve assembly between an open position that provides a fluid passageway for the injection fluid from the tubular into a subterranean formation and a closed position that closes the fluid passageway for the injection fluid from the tubular into the subterranean formation, based upon a density of the injection fluid.

The disclosure presents processes to locate one or more quantum gravimeters at a hydrocarbon well site, with at least one quantum gravimeter at a surface location. One or more additional gravimeters, whether quantum gravimeters or non-quantum gravimeters, can be located downhole a wellbore of the well site. Gravitational data collected from various gravimeters can be analyzed to produce analyzed gravitational parameters and subterranean formation parameters. In some aspects, the gravitational data can be processed, such as by an inversion algorithm or a noise reduction algorithm. The generated results can be used to calibrate non-quantum gravimeters located proximate the well site or downhole the wellbore, identify a depth and direction of a water front, identify the fluid flow of hydrocarbons or water in the subterranean formation, to identify orphaned hydrocarbon reservoirs, or other characteristics of fluid flow or subterranean formation parameters, such as subterranean formation damage.

Quantum gravimeters for hydrocarbon reservoir analysis

An apparatus for supplying clean fluid to a component in a well may include a filter. The filter may include a housing having an outlet, a conical permeable element disposed at least partially inside the housing, and a tapered helical coil disposed at least partially inside the permeable element.

A downhole sealing tool and method use a swellable material (e.g., a swellable rubber or a swellable metallic material) with increased surface area for faster reaction with an activation fluid. In one example, a swellable metallic sealing element and actuator are carried on a tool mandrel for lowering into a wellbore on a conveyance. The sealing element includes a plurality of expandable metal wires supported along the tool mandrel. The expandable metal wires comprise a swellable metallic material that swells in response to exposure to an activation fluid. The actuator is used to separate at least a portion of the expandable metal wires, to increase a surface area exposed to the activation fluid and thereby accelerate the reaction.
