Systems, methods, and computer program products can be used for determining the amount of oil removed by a miscible gas flood. One of the methods includes identifying locations of oil within a volume representing a reservoir rock sample. The method includes identifying locations of gas within the volume. The method also includes determining the amount of oil removed based on locations within the volume where oil is either coincident with the gas or is connected to the gas by a continuous oil path.

A flow control system selectively regulates production of a fluid from a well. The flow control system includes a plurality of flow control devices, each flow control device rotatable by a portion of the fluid and selectively directing the portion of the fluid through an outlet of the flow control device based on the density of the fluid. The system further includes a regulator valve controlled at least in part by the portion of fluid exiting the outlet of the flow control device. The regulating valve regulates production of a remaining portion of the fluid from the well.

The present invention provides a system and method for use of desulphated injection water from offshore platforms for utilization in inhibition squeeze operations. The system is capable of increasing the treatment capacity by joining the pumping system from the stimulation vessel with the water injection system from the offshore platform.

In the initial treatment step, according to the method of this invention, the fluid containing the inhibitor is pumped exclusively by the vessel, followed by an aqueous overflush, where the injection water is mixed with part of the inhibitor cushion pumped by the stimulation vessel.
