A computerized method and system for of operating an oil/gas facility for processing oil and gas from a reservoir. The method includes steps of receiving input data concerning condensate phase and gas phase components in the reservoir, the input data characterizing both phase components, determining a pore capillary pressure of the reservoir based on the received input data which characterizes the phase components, determining PVT parameters of the reservoir phase components based on the determined pore capillary pressure, and controlling a setting of the oil/gas facility based on the determined PVT parameters of the reservoir phase components.

An inflow promotion arrangement including a housing; and a promotion configuration within the housing, the promotion configuration actuatable by fluid from a relatively higher productivity index zone of a wellbore.

Embodiments of the present invention provide a method for artificially recharging a target reservoir in a geological formation using powered water injection from a local source aquifer in the geological formation. The method comprises detecting chemical properties of water in the source aquifer, determining whether the water in the source aquifer is compatible with water in the target reservoir based on the chemical properties, activating an electrical submersible pump (ESP) positioned between target reservoir and the source aquifer to inject water from the source aquifer into the target reservoir, detecting downhole pressure, temperature and water flow rate conditions at the ESP, and controlling a rate at which the ESP injects water using the downhole pressure, temperature and water flow rate conditions.

There is provided system and methods for restimulating a hydrocarbon producing well using water and pressures below the closure pressure, which results in production rates approaching the initial production rate of the well. There is provided multiple restimulation techniques using water based fluids at or below the closure pressure of the well, which results in production rates approach that of the prior rate upon stimulation.

The present invention discloses a pressurized test device and method for in-situ mining natural gas hydrates by jets, relating to the field of exploitation of marine natural gas hydrates. The device comprises an injection system, a jet breakup system, an annular pressure system, an axial pressure system, a backpressure system, a vacuum system, a simulation system, a collecting and processing system and a metering system, all of which can operate independently by controlling pipe valves on pipelines. The loading of the confining pressure of the device is independent of the loading of the axial pressure, without interference to each other. Meanwhile, the jet breakup process of natural gas hydrate-containing sediments can be observed in real time by a video camera.

A downhole system includes a first tubular having a first end, a second end, and an intermediate portion having an inner surface defining an interior. The second end includes one of a screen liner and a casing shoe. A second tubular is coupled to the first end of the first tubular. The second tubular includes a terminal end portion, a second end portion and a ported zone arranged between the terminal end portion and the second end portion. The terminal end portion and the ported zone extend into the interior of the first tubular. A packer member is arranged on the second tubular between the terminal end portion and the ported zone. The packer member is selectively expandable to seal against the inner surface to fluidically isolate the one of the screen liner and casing shoe from the ported zone.
