Abstract: Methods and systems for providing distributed functionality to a plurality of clients comprise the use of more provider servers which publish function objects to clients upon request. Each function object corresponds to a function that is supported by the provider server or a connected downstream provider server. Group definition can also be published by the provider server. The client software is dynamically responsive to the functions which are available from the provider servers and permit a user of the client to select specific functions from the set of available functions for execution. Functions can be executed by modifying the function object to include specific parameter values and sending it to a provider server. Results of function evaluation can be returned in a further modified function object. In a particular implementation, the functions return financial information about specified financial securities and the client graphically displays the returned data.

Abstract: An effective laboratory method for developing complete capillary pressure curves involves directly measuring an oil/water saturation profile within a cylindrical porous rock core plug. The saturation profile, which includes a free water level, is established under a known pressure gradient induced by centrifuging and is measured using image mapping techniques. The free-water level is established at a desired position within the length of the core plug and provides a reference position of zero capillary pressure to facilitate measurement of both positive and negative capillary pressures.

Abstract: A method is provided for evaluating the potential productivity of a zone of a formation in regard to hydrocarbons substantially free of water, and according to another aspect the method can determine the residual saturation of any porous media with respect to any particular saturating liquid. At least one sample from a zone is saturated with a saturating liquid, such as a saturating liquid comprising water, and the nuclear magnetization of the liquid is substantially inverted by means of at least one NMR radio frequency pulse. A component of the nuclear magnetization is detected at different delay times following application of such a pulse, from which the delay time (NMR zero time) is determined at which the magnetization component is zero. Potential productivity of dry hydrocarbons from the zone and/or residual saturation of the core sample is determined based on the NMR zero time.

Abstract: A method is provided for determining the relative wettability of a sample of a porous media with respect to a first liquid and a second liquid. The method includes the steps of providing the sample at a partially saturated state with respect to the first liquid; obtaining a first nuclear magnetic resonance (NMR) parameter value for the partially saturated sample; exposing the partially saturated sample to the second liquid for a predetermined period of time, wherein the second liquid is treated with a paramagnetic species such that the presence of the second liquid in the sample does not substantially affect the NMR signal response of the sample; obtaining a second NMR parameter value for the sample after exposure to the second liquid; and determining the relative wettability by comparing the first and second NMR parameter values.

Abstract: A method is provided of determining saturation values corresponding to particular locations in a sample of a porous media, whereby such saturation values can be used in conjunction with corresponding capillary pressures to derive a capillary pressure curve. The method of the invention involves the use of nuclear magnetic resonance (NMR) imaging to obtain NMR intensity values corresponding to the locations of interest. Intensity is related to saturation by an appropriate function which is employed to determine the saturation values from the intensity values.
