Abstract:

An apparatus for continuous measurement of a geomaterial is disclosed. The apparatus includes a measuring device and a flat bed operatively coupled to the measuring device. The measuring device includes a moving head configured to move in a longitudinal direction relative to a core section of the geomaterial and a first probe coupled to the moving head and configured to continuously measure a property of the core section.

Abstract:

A method for continuous measurement of heterogeneity of geomaterials. The method includes identifying a core section from a first well within a field, obtaining the core section from the first well, and obtaining a continuous measurement of the core section. The method further includes overlaying the continuous measurement with a portion of a log response for the first well to obtain an overlay, associating an observation with the overlay to obtain an integrated overlay, and analyzing the integrated overlay to determine a heterogeneity of the core section. The method further includes identifying a location in the core section from which to obtain a sample based on the heterogeneity, obtaining the sample from the core section, and analyzing the sample to obtain an analysis result. The method further includes developing a continuous model for the first well using the integrated overlay and the analysis result and presenting the continuous model.

Abstract:

A packet-switched facsimile communication system operable in a store-and-forward mode is provided for enabling substantially simultaneous full-duplex communication between a plurality of telecommunications terminals, such as facsimile transceivers, over a communications network with a plurality of other facsimile transceivers having access to the communications network and with which such communication is desired. The disclosed packetizing of data and transmission thereof in a store-and-forward mode with dynamic routing provides a highly efficient utilization of the transmission facilities, substantially error-free data transmission and a handshake capability between a wide variety of dissimilar and otherwise incompatible facsimile machines having differing protocols, modulation techniques and other speed and code characteristics. Large blocks of data and other message information from facsimile data terminals are subdivided into data packets prior to transmission, converted into a systemwide compatible protocol, compressed, transmitted independently and time multiplexed with other packetized data from other terminals on the communications network, stored and forwarded on a priority basis and in accordance with network availability at one or more switching nodes in the network, reassembled from the received packets at a destination processor into the original data messages for coupling to the message destination terminals such that the received message is decompressed and reconverted into a format compatible with the destination terminal characteristics to enable information interchange therebetween.

International Classification:

Abstract:

A method of characterizing free volume of a rock sample includes test operations that measure pressure decay data from stepwise pressurization of the rock sample with a test gas. An initial free volume of the rock sample is calculated as a function of the pressure decay data. An initial maximum storage capacity of the rock sample is derived as a function of the initial free volume of the rock sample. A volume of test gas adsorbed as a liquid is calculated based on the maximum storage capacity of the rock sample. An updated free volume of the rock sample is calculated based on the initial free volume and the volume of the test gas adsorbed as a liquid. An updated maximum storage capacity of the rock sample is derived as a function of the updated free volume. Calculations of the volume of test gas adsorbed as a liquid, the updated free volume and the updated maximum capacity of the rock sample can be repeated until the updated maximum storage capacity and the updated free volume converge respectively to give the maximum storage capacity and free volume of the rock sample.
