    Abstract: Analysis evaluates formation fluid with a downhole tool disposed in a borehole. A plurality of possible constituents is defined for the formation fluid, and constraints are defined for the possible constituents. The constraints can include boundary constraints and constraints on the system's dynamics. The formation fluid is obtained from the borehole with the downhole tool over a plurality of time intervals, and density of the obtained formation fluid is obtained at the time intervals. To evaluate the fluid composition, a state probability distribution of the possible constituents of the obtained formation fluid at the current time interval is computed recursively from that at the previous time interval and by assimilation the current measured density of the obtained formation fluid in addition to the defined boundary/dynamic constraints. The probabilistic characterization of the state of the possible constituents allows, in turn, the probabilistic inference of formation properties such as contamination level and GOR.

    Abstract: The present invention generally relates to a deepset wireline retrievable safety valve for controlling fluid flow through a production tubing string. In one aspect, a valve for use in a wellbore is provided. The valve includes a housing having a bore. The valve further includes an actuator sleeve movable within the housing between a retracted position and an extended position. The actuator sleeve in the retracted position allows a flapper member to obstruct the bore in the housing. Additionally, the valve includes a first piston member attached to a first side of the actuator sleeve and a second piston member attached to a second side of the actuator sleeve, wherein wellbore fluid pressure acts on the first piston member, which results in a first force, and acts on the second piston, which results in a second force, and the first force and the second force are applied to the actuator sleeve in an opposite direction.
