A communications network includes packet-based networks that are coupled to various network elements. A method and apparatus is provided to implement telephony services in the communications network. The architecture for providing the telephony services may include several layers, including a network elements layer, an interface layer, and a services/application layer. The services/application layer is decoupled from the specific implementations of the network element layer so that a more flexible and convenient mechanism is provided to create telephony services. The telephony services may be implemented in software modules written in one of several possible languages, such as a telephony scripting language (TSL) or other language. The interface layer includes various components, including translation components to interpret and execute the modules that are in the services/application layer, communications components to provide mechanisms to send commands to network elements layer to perform the specified telephony services, and representation components that describe the functions, tasks, and other details associated with network elements.

Providing telephony services in a communications network

A program and method for identifying connectivity of well perforation locations to cells of a reservoir description that meet selected pay criteria. First, a pay indicator is assigned to the cells that satisfy the selected pay criteria. A connectivity indicator is then assigned to the pay indicator-assigned cells that correspond to said well perforation locations. Next, a connectivity indicator is assigned to the pay indicator-assigned cells that are connected, either directly or indirectly through another said pay-indicator-assigned cell, to the well perforation location connectivity indicator-assigned cells. The result is construction of a connectivity index array for the reservoir description that differentiates the connectivity indicator-assigned cells from cells that are not assigned a connectivity indicator. The array may be used to calculate the total volume of the connectivity indicator-assigned cells, thereby estimating the drainage volume, i.e., the total producible volume, of the reservoir description.
