Abstract: An apparatus, system, and method are disclosed herein. In one embodiment, the apparatus includes a plurality of valves. Each valve of the plurality of valves is associated with a respective production zone of a well. Each valve includes a valve body having a passage and an inflow fluid input through which a formation fluid from the respective production zone associated with the valve is to enter the passage of the valve body. Each valve further includes a sensor located within the valve body to detect a density of the formation fluid. The apparatus further includes a processor programmed to determine a fraction of a subject fluid in the formation fluid based on the density of the formation fluid and a density of the subject fluid.

Abstract: In one embodiment, the apparatus includes a production tubing for carrying fluids from a producing zone to a surface, and a three-way valve coupled to the production tubing, the three-way valve including an inlet from the production tubing, an outlet to the production tubing, and an inlet from the borehole surrounding the three-way valve. The apparatus further includes a resonant tube densitometer disposed in the outlet to the production tubing, the resonant tube densitometer configured to measure the density of the fluids. A flow meter is disposed in the outlet to the production tubing, the flow meter configured to measure volumetric flow of the fluids.

Abstract: A valve body includes a mixing chamber within the valve body, a plurality of passages through the valve body into the mixing chamber, and a sensor located within the valve body. The sensor has a sensor output representing a property of a fluid within the valve body. A processor is coupled to the sensor output. The processor is programmed to use the sensor output, a density of oil and a density of a subject fluid to determine a fraction of the subject fluid in a fluid flowing through one of the plurality of passages.

Abstract: A production tubing carries fluids from a producing zone to a surface. A resonant tube densitometer measures the density of the fluids carried by the production tubing. The resonant tube densitometer has a tube. A longitudinal section of the production tubing is the tube of the resonant tube densitometer.

Abstract: An example device in accordance with an aspect of the present disclosure includes a splice housing body comprising a raceway within which optical fibers and electrical cables can be positioned, at least one port through the splice housing body to which a pressure fitting for optical fiber or electrical cable can be mounted, a base to which the splice housing body may be removably attached, and a port in one of the splice housing body or base for inserting fluid in the splice housing body.

Abstract: An energized composite metal to metal seal. A sealing device includes a metal seal with a metal sealing surface facing radially outward, and another metal sealing surface facing radially inward; and a nonmetal seal including a nonmetal sealing surface positioned proximate one metal sealing surface and facing radially outward, and another nonmetal sealing surface positioned proximate the other metal sealing surface and facing radially inward. A method of sealing between a housing assembly and a closure member includes applying a pressure differential across the sealing device while the sealing device seals between the housing assembly and the closure member, and the pressure differential increasing contact pressure in a metal to metal seal between the housing assembly and a metal sealing surface on the metal seal, and increasing contact pressure in a metal to metal seal between the closure member and another metal sealing surface on the metal seal.

Abstract: A well system can include a flow control device which regulates flow of a fluid from an interior of the device outwardly through an exit port, and a deflector which outwardly overlies the exit port and provides fluid communication between the exit port and an annulus formed radially between the deflector and a wellbore lining. The deflector can diffuse the flow of the fluid prior to impingement on the wellbore lining. A flow control assembly can include a flow control device which regulates flow of a fluid from an interior of the device outwardly through an exit port, and a deflector which outwardly overlies the exit port, the deflector including at least one opening, and the opening being circumferentially offset relative to the exit port. A form of an interior surface of the deflector and/or an exterior surface of the flow control device can diffuse the flow of the fluid.
