A technique provides a desired control over incremental actuation of hydraulic devices. A hydraulically actuated tool is combined with a control module. The hydraulically actuated tool has an actuator piston positioned in a piston chamber and movable between operating positions. The control module comprises a hydraulic indexing circuit arranged to enable incremental movement of the actuator piston in a first direction and full stroke movement in a second direction based on hydraulic input delivered via control lines. The hydraulic indexing circuit comprises an indexing piston system and at least one check valve working in cooperation with the indexing piston system to enable the incremental and full stroke movements.

A method, computer system, and computer program product are provided for a graphical user interface that presents a quantification of CO2 emissions in a manufacturing process. A selection of a material is received, and the selection is displayed in a graphic user interface. Amounts of material and energy consumed in a manufacturing process are calculated. A chemical composition of the material is decomposed into a set of constituent elements. A first quantity of CO2 emissions is estimated based on the amount of material consumed and a first CO2 emission factor based on a proportional composition of the set of constituent elements in the chemical composition. A second quantity of CO2 emissions is estimated based on the amount of energy consumed and a second CO2 emission factor based on an energy source used in the manufacturing process. Total CO2 emissions, based on both the first and second quantities, are then displayed in the graphic user interface.

A technique facilitates both actuation of a well tool and chemical injection at a corresponding well zone or well zones. In a multi-zone operation, the well system may comprise a plurality of operating modules coupled with corresponding actuators and chemical injection devices. The well system is deployed downhole to a desired location in a borehole, e.g. a wellbore. The operating modules may be selectively shifted via electrical input to enable a desired chemical injection and/or actuation of the actuator (and thus the well tool) at desired well zones. In some embodiments, the operating modules may comprise contingency circuits to enable the chemical injection without electrical input.

A technique facilitates operation of an actuator via an operating module. The actuator and the operating module are constructed to enable operation in a wide variety of environments and applications. The operating module is coupled to the actuator and is operable in a plurality of modes, such as an electro-hydraulic mode, a pure hydraulic mode, and a mechanical mode. A desired mode of operation is selected and the operating module enables shifting of the actuator via the selected mode.
