    摘要: Apparatus for obtaining horizontal and/or vertical permeability measurements through a probe having an elongate aperture. The invention uses the elongate aperture in the probe to orient fluid flow in an earth formation horizontally or vertically. The elongate aperture is approximated through the use of a single elongate opening or through the use of a group of aligned openings of varying shapes. Measurements can be taken at different orientations by including additional probe openings along more than one axis.

    摘要: A rubber pocket is described that is suitable for use on tubing, such as a packer-type seal, on casing, such as a cement-type seal, or on liners. The rubber pocket may contain cement particles, rubber particles, swellable particles, cement filled rubber particles, cement filled swellable particles, calcium oxide, magnesium oxide, magnesium sulfate, iron (III) oxide, calcium sulfoaluminate, clay, magnetic particles and/or reactants such as crosslinkers, retardants or epoxy. The particles may be bulk spheres, bulk fibers, hollow spheres, hollow fibers, etc. The rubber pocket or bladder may also be fully or partially filled with fluids such as polymer reactants. The pocket may also be empty or contain a small volume of reactants. The slurry or epoxy or other type of fluid and granular solid or injectable matter can be injected after the completion positioning downhole.

    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: Fluid flow measurements are made in situ using a repeat formation tester with a modified probe aperture, or on rock samples using a mini-permeameter with a modified probe aperture. The modified probe aperture has an elongate cross-section, such as elliptic or rectangular. A first flow measurement is made with the longer dimension of the probe aperture in a first orientation (e.g., horizontal or vertical) with respect to the formation bedding planes. A second flow measurement is made with the probe aperture orthogonal to the first orientation, or with a probe aperture of non-elongate (e.g., circular) cross-section. Simultaneous equations relating values of known and measured quantities are solved to obtain estimates of local horizontal and/or vertical formation permeability.
