Title: Computer-implemented systems and methods for forecasting performance of water flooding of an oil reservoir system using a hybrid analytical-empirical methodology
Inventor: RAI KHYATI
IPC: G06F19/00
Filed: 2011-10-04
Abstract: Computer-implemented systems and methods are provided for generating corrected performance data of water flooding of an oil reservoir system based on application of a statistical correction factor methodology (SCF). For example, data related to properties of the oil reservoir system and data related to a water flooding scenario are received. Water flooding performance data is generated based on application of an analytical water flooding performance computation methodology. Based on application of the SCF methodology to the generated water flooding performance data, corrected water flooding performance data is determined, representative of oil recovery by the water flooding of the oil reservoir system. The SCF methodology can also be used to evaluate water production based on parameters such as water-oil ratio and water cut, identify possible analog reservoirs that have similar water production performance, and calculate a Gross Injection Factor to account for water loss in the reservoir.

Abstract: The invention relates to an arrangement for actuating a shut-off valve with a tapered plug, which are used in particular in the chemical, in particular the petrochemical industry, for closing and opening pipes carrying fluid flows. An arrangement according to the invention for actuating a shut-off valve with a tapered plug has a housing (1) in which a hollow actuating cylinder (4) is coaxially supported for rotation and on which an actuating shaft (3) aligned with the coaxial axis (2) is firmly attached. An output cylinder (5) is coaxially arranged in the hollow actuating cylinder (4).  The output cylinder (5) is movable relative to the hollow drive cylinder (4) axially and radially. A spindle (6) is attached on the output cylinder (5) opposite the actuating shaft (3) and aligned with the coaxial axis (2), with a tapered plug (7) being fastened on the end of the spindle facing away from the output cylinder (5). At least one radially outwardly directed pin (8) is arranged on the outer peripheral surface of the output cylinder (5). The outer surfaces of the housing (1) and of the hollow actuating cylinder (4) have each at least one guideway (10, 11) extending over a radial sector of the outer surfaces, with which the pin (8) is operatively connected in the manner of a respective sliding block. At least the guideway (10) arranged in the outer surface of hollow actuating cylinder (4) is formed as a through-opening through which the pin (8) passes. The invention has the particular advantage of a simple gear structure with few gear parts, with which a sequence of movements involving raising, rotating and lowering the tapered plug for a reliable and low-wear operation of a shut-off valve can be realized.
