A downhole apparatus ( ) for determining the constituent composition of a produced fluid is disclosed. The apparatus ( ) includes a vessel ( ) having an interior chamber ( ) that receives and contains a sample of the produced fluid. In the interior chamber ( ), the sample of the produced fluid is allowed to separate into its constituents. A gauge ( ) having an array of transmitter elements (E -E ) and an array of corresponding receiver elements (R -R ) disposed oppositely of one another on the vessel ( ), is used to transmit and receive energy waves that propagate through the sample of the produced fluid. The receiver elements (R -R ) detect changes in absorption or scattering of the energy waves transmitted from the corresponding transmitter element (E -E ) caused by the constituent of the sample of the produced fluid through which that energy wave propagated. Based upon these changes in the energy waves, the level of an interface between the constituents is identified such that the constituent composition of the produced fluid may be determined.

A removable injection valve insert assembly is disclosed for deploying in production tubing of a well casing. The production tubing includes a landing nipple with an inlet and a sliding side-door which covers and seals the inlet when in a closed position and uncovers the inlet when in an open position. The insert assembly controls the flow of flushing fluid that is injected into the inlet from an annular source between the casing and the production tubing. The valve directs the controlled flushing fluid to an injection line, which in turn injects the flushing fluid into the production stream of the well. Preferably, the injected flushing fluid is injected below the casing perforations. The insert assembly comprises a body having upper and lower ends, a first passage formed in the body for receiving the fluid from the inlet and a second passage in communication with the first passage for housing a flow control valve. The body also includes a by-pass passageway which allows production flow across the insert. The second passage extends to the lower end of the body and receives the injection line. The injection line extends down the production tubing to the casing perforations to inject flushing fluid into the production flow to reduce concentrations of salt and other elements in the production flow and to dislodge deposits that may build up in the perforations.

A fishing rod handle having an upper elongate segment, a lower elongate segment, and an arcuate connecting segment joining the upper and lower segments so that the handle has generally a U-shape. The upper and lower segments include upper and lower portions shaped to be grasped by a human hand, and the lower segment includes a reel seat positioned forwardly of the lower portion. The handle may be grasped comfortably by both hands while casting such that the hands are positioned in different planes. In a preferred embodiment, the handle is weighted so that the center of gravity of a combination of the handle and an associate rod shaft lies along the upper segment directly across from the reel seat.

A valve having a tubular body with a valve seat and valve member controlled by a valve operator with provisions for latching the valve operator with the valve member in partially open position utilizing a snap ring which is propped out into a groove in the body and provides a stop maintaining the valve partially open against a spring and in which the valve operator has a receiving groove which receives the snap ring and maintains it in an out-of-the-way position upon movement of the valve operator toward full valve-open position.

Valve

A cooperating landing nipple and subsurface safety valve in which the closure springs for the subsurface safety valves are carried by the landing nipple and the actuator and the pressure responsive member for effecting opening and closing of the valve are carried by the subsurface safety valve.

A well system for injection into a selected formation in each tubing string in a multiple formation dual string well completed for through flow line/pumpdown operation, utilizing a string of tools which may be pumped down tubing to open selected tubing sleeve valves between packers. Each tool string includes a pressure openable injection valve which seals across the open sleeve valve and is opened for formation injection flow at preselected pressures by application of tubing pressure at the surface. One type of injection valve closes to flow through when pressure opened for injection flow. The other injection valve is closed to injection flow on insertion of a closing prong having a through flow passage. Both injection valves and their respective tool strings may be individually retrieved closing sleeve valves in each tubing and the formations to injection.
