176 results about "Eclipse" patented technology

An eclipse is an astronomical event that occurs when an astronomical object is temporarily obscured, either by passing into the shadow of another body or by having another body pass between it and the viewer. This alignment of three celestial objects is known as a syzygy. Apart from syzygy, the term eclipse is also used when a spacecraft reaches a position where it can observe two celestial bodies so aligned. An eclipse is the result of either an occultation (completely hidden) or a transit (partially hidden).

System and method to control transactions on communication channels based on universal identifiers

The present invention is a method to control communication channels using universal and persistent identifiers in circuit/packet switched or converged networks. The method involves linking domain specific addresses or concrete identifiers of communication end points within or across channels, domains and networks with an abstract, persistent and universal identifier that represents the single point of contact or principal identity of the user. The principal identity can specify parameters of inbound/outbound communication relationships with other specified/unspecified users/entities inter-alia through default/specific levels of control in communication relationships on/across/through normal or alternate channels, domains, applications, networks, etc., based on universal/persistent identifiers such as XRI. All transactions originating from, or terminating on, the principal identity are authenticated, asserted securely and routed automatically to an appropriate channel based on the principal identity's current context (state, location, presence, etc.) and privileges (or contracts) defined in rules created by the principal identity for access, usage, privacy, synchronization, compliance, expiry, etc. The principal identity is also empowered with multi-level control over attributes and metadata including rules for what data to expose/share and what data to eclipse/hide for which user. Control/user data, or traffic, and program/client/sequence logic, may be resident/executed/exchanged/carried on, or across, diverse networks/channels/media/devices/domains etc.

Inflow performance relationship for horizontal wells producing oil from multi-layered heterogeneous solution gas-drive reservoirs

ActiveUS20150168596A1Small and acceptable average absolute errorLess varianceElectric/magnetic detection for well-loggingSurveyHorizontal wellsEclipse
The invention investigates the effects of reservoir heterogeneity on IPR curves for horizontal wells drilled in heterogeneous solution gas drive reservoirs. To achieve the desired objective, a commercial simulator Eclipse is utilized to develop IPRs for horizontal wells producing oil from solution gas drive reservoirs. Firstly, a simulation model is developed where a base case is considered with typical rock, fluid and reservoir properties using a black oil model. Dimensionless IPR curves are generated by obtaining a set of points relating to flowing bottom-hole pressures to oil production rates. The effects of several reservoir and fluid properties such as bubblepoint pressure, oil gravity, residual oil saturation, critical gas saturation, initial water saturation, porosity and absolute permeabilities on the calculated curves are investigated.
Reservoir heterogeneity is included in the simulation model by incorporating a semi-variogram function. Finally, a new single empirical IPR model is obtained for horizontal wells producing oil from heterogeneous solution gas drive reservoirs suitable for systems with different reservoir permeability. The new empirical IPR model is then compared to published correlations and is found to have a small and acceptable average absolute error of less than 2%. Furthermore, the invention also shows that bubble point pressure has significant effect on dimensionless IPR curves. However, plots for other properties indicate that although the curves are not identical, they are similar in shape and demonstrate much less variance than the bubble point pressure plot. Therefore, these properties have only a minor effect on calculated, dimensionless IPR curves.
