    摘要： An oilfield data analysis system is based on a four-tier software model which includes a “shared earth model” and a federation of “directory services”. The first tier is a universal graphical user interface (GUI) which can operate on any inexpensive computer as well as on an expensive workstation, i.e. a “web browser”. The second tier is an application server which is coupled to users via the worldwide web and serves geoscientific software applications. The third tier is a geometric modelling system where geometric data is stored and processed. The third tier embodies the “shared earth model”. The fourth tier is a database management system where non-geometric data is stored. According to the invention, there can be (and preferably are) multiple instances of each tier. Communication of data between different tiers is accomplished via XML data exchange. According to a presently preferred embodiment, the geoscience applications served by the second tier are written as JAVA servlets and applications may communicate with each other without human direction by registering requests with “directory services”. Applications interested in certain types of data “listen” for “data events” being registered with directory services. The cost of utilizing an application can be based on a time-rental billing operation which is carried out automatically via directory services.

    摘要： A method for characterizing a property of a subterranean formation including collecting well log and seismic data, inverting the data, processing for upscaled petrophysical parameters, constructing a flow model that generates saturation, pressure and temperature, constructing seismic velocity relationships from the results of the flow model, and constructing a seismic model. Some embodiments may form a full waveform model or a ray tracing model. Some embodiments may generate a velocity profile and/or waveforms using the profile. Some embodiments may use the parameters to form a reservoir model or to recover hydrocarbons from the formations. Some embodiments build a reservoir model of CO2 injection or CO2 presence after injection or for simulating CO2 presence in a subterranean formation. Some embodiments may also quantify CO2 properties in the reservoir or predict CO2 profile evolution over time in the reservoir including spatial distribution. Some embodiments may also predict CO2 profile evolution over time in a reservoir and risk assessment, estimate storage capacity of the reservoir, or select a storage site. Some additional embodiments may also predict fluid front arrival, fluid front monitoring, fluid movement monitoring, or injectivity. Some additional embodiments may generate saturation profiles or a pressure.

    摘要： A wireline logging tool and method for fluid monitoring and flow characterization in individual zones of controlled salinity is disclosed. The tool and method advantageously facilitate zone-specific testing. Sets of packers are used to create hydraulically distinct zones proximate to the tool. Coiled tubing and isolation valves are used to selectively introduce and remove an electrically conductive fluid such as brine to and from a selected zone. Individual sensors are disposed near each zone to make zone-specific measurements while fluid properties are changed, e.g., while salinity is changed to cause salinity fronts in the formation.

    摘要： A well completion and related method are provided for formations susceptible to simultaneous production of oil and water. In one embodiment, two closely spaced, preferably horizontal wellbores are drilled from a single well into the reservoir. The reservoir rock surrounding one leg (typically the upper leg) is chemically treated to make it hydrophobic, whereas the reservoir rock surrounding the other leg is chemically treated to make it hydrophilic. Separate production tubing and a dual completion is installed in order to enable independent flow from each leg. Drawdown pressures in both legs are controlled to be sufficiently close to each other such that only oil flows into one leg and only water into the other. The water produced is re-injected downhole or brought to the surface.

    摘要： An apparatus and method of measuring a parameter characteristic of a rock formation in an oil well is provided with a device for generating a sensing field within a volume of the rock formation and a device for causing a flow through the volume in the presence of the sensing field, further including sensors responsive to changes in the volume, wherein a sensor response is indicative of the amounts of fluid, particularly hydrocarbon and water saturations and irreducible hydrocarbon and water saturations. Measurements can be made before the flow affects the measuring volume and after onset of the flow through the measuring volume.
