Including Production Of Earth Fluid By Driving Fluid Patents (Class 166/252.1)
  • Publication number: 20020007947
    Abstract: The invention includes a method of scheduling cyclic steaming of a group of petroleum-containing wells including: inputting to a production-predicting means a group of data describing at least in part the past cyclic steaming and resulting production of a group of petroleum-containing wells; processing the data in the production-predicting means and outputting a group of production predictions for the group of wells during a future steaming cycle; inputting the group of production predictions into an optimization means; inputting an initial steaming cycle schedule for the group of wells into the optimization means; processing the group of production predictions and the initial steaming cycle schedule in the optimization means by the steps including: determining a ranking for the initial steaming cycle schedule for the group of production predictions against a pre-determined ranking criteria; producing a group of new steaming cycle schedules based on the ranking of the initial steaming cycle a schedule optimiz

  • Publication number: 20010050170
    Abstract: The present invention provides systems and methods for performing production testing in open holes and in cased holes that avoid transporting formation fluid to the surface. The invention essentially comprises a test string for testing a production zone intersecting a wellbore. The string further comprises a fluid communication member allowing flow of fluid therethrough, a sealing device for isolating a production zone intersecting said wellbore to allow fluid flow from said production zone into said fluid communication member, a second sealing device spaced apart from said first sealing device for isolating a second injection zone intersecting said wellbore, a pump for pumping fluid between zones, and flow control devices.

  • Patent number: 6325147
    Abstract: Process intended for enhanced recovery of a petroleum fluid by combined injection of an aqueous phase saturated with acid gases. The process esentially consists in continuously injecting, into the oil reservoir, a mixture of an aqueous phase and of a gas at least partially soluble in the aqueous phase and at least partially miscible with the petroleum fluid, by controlling the ratio of the flow rates of the aqueous phase and of the gas so that the latter is always in a state of saturation or oversaturation at the bottom of the injection well(s). The aqueous phase saturated or oversaturated with gas comes into contact with the petroleum fluid present in the reservoir. The gas dissolved in the aqueous phase is at least partially transferred to the liquid hydrocarbon phase, thus causing swelling and viscosity reduction of this phase, which favors migration of the petroleum fluid towards a production zone.

  • Patent number: 6318464
    Abstract: An improved method for the recovery of hydrocarbons from a hydrocarbon deposit comprising the steps of introducing a diluent gas along a predominantly horizontal injection well drilled at the base of a hydrocarbon deposit; creating an initial communication path with a predominantly horizontal production well spaced laterally apart from the injection well; gradually enriching the diluent gas with a hydrocarbon solvent to produce a hydrocarbon solvent vapor which is saturated at reservoir conditions; continuously circulating the diluent gas and the saturated hydrocarbon solvent vapor through the hydrocarbon deposit; and producing mobilized hydrocarbons from the hydrocarbon deposit.
