Abstract: Systems and methods for controlling a drilling rig. The system includes a first layer including a plurality of subsystem controllers coupled with a plurality of rig subsystems, the plurality of subsystem controllers being configured to control operating parameters of the plurality of rig subsystems. The system also includes a second layer configured to receive information from the first layer based on an operation of the plurality of rig subsystems, and to provide control of the plurality of rig subsystems. The system further includes a third layer configured to execute one or more process applications and to provide a task-based command to the second layer.

Abstract: A method for estimating hydrocarbon volume in a layered subsurface formation includes determining a vertical resistivity and a horizontal resistivity in the formation. A bound water saturation and a total porosity of individual layers of the formation are determined. Values of horizontal resistivity and vertical resistivity of the formation are calculated based on the bound water saturation and the total porosity for each layer and on an estimated irreducible bulk volume of water in each layer. The estimated values are compared to the determined horizontal resistivity and vertical resistivity. The estimated irreducible water saturation in each layer is adjusted and estimating the values is repeated until differences between the estimated values and the determined vertical and horizontal resistivity values fall below a selected threshold. The hydrocarbon volume is estimated from the adjusted irreducible water saturation for each layer.
