Abstract: Ancillary service bid generation systems and methods are described herein. One example of a method for ancillary service bid generation includes quantifying an electric demand for a number of electrical devices, determining an electric demand reduction capability of the number of electrical devices for a number of event scenarios, and preparing an ancillary service bid based on the electric demand reduction capability of the number of electrical devices.

Abstract: By using reactive shaped charges, a dynamic underbalance effect associated with detonation of a perforating system is enhanced without compromising shot density. Fewer shaped charges can be loaded to achieve the same or better effective shot density as a gun fully loaded with conventional shaped charges, thereby increasing the free volume within the gun while creating debris-free tunnels with fractured tips and substantially eliminating the crushed zone surrounding each perforated tunnel. Further, the strength and grade of gun steel required to construct the gun can be reduced without compromising the amount the gun swells following detonation.

Abstract: By using reactive shaped charges to perforate failure prone formations, the present invention is able to keep formation sand in place and increase productivity. An efficient flow distribution is surprisingly produced without requiring surge flow or post-perforation stimulation. Further, using the secondary reactive effects of reactive shaped charges allows for the reduction of the risk of erosion and minimization of sand production. In a preferred embodiment, a liner capable of producing a strongly exothermic intermetallic reaction between liner components within and around the tunnel is used to achieve a high percentage of substantially clean and enlarged perforation tunnels conducive to flow or gravel packing.

Abstract: A connectorized fiber optic communications cable can comprise a section rated for indoor service and a section rated for outdoor service. A continuous optical fiber can extend through the indoor-rated section and the outdoor-rated section, for example from an outdoor-rated connector on the outdoor-rated section to an indoor-rated connector on the indoor-rated section. The cable can be installed via feeding the section rated for indoor service through a hole in a building, such as a home, to a communication or computing device within the building. The section rated for outdoor service can be buried underground and extended to another communication or computing device located outside the building.

Abstract: An apparatus for perforating a casing string including a first module and a second module, each including a gun assembly. The first module is positioned longitudinally adjacent the second module on the casing string. Each module contains a firing assembly for igniting the gun assembly in the first module, a remote signaler to remotely detonate the firing assembly, and ballistic transfer assembly for igniting the gun assembly in the second module. The ballistic transfer assembly includes a booster charge.

Abstract: By substantially eliminating the crushed zone surrounding a perforation tunnel and expelling debris created upon activation of a shaped charge with first and second successive explosive events, the need for surge flow associated with underbalanced perforating techniques is eliminated. The break down of the rock fabric at the tunnel tip, caused by the near-instantaneous overpressure generated within the tunnel, further creates substantially debris-free tunnels in conditions of limited or no underbalance as well as in conditions of overbalance.

Abstract: By removing material of low permeability from within and around a perforation tunnel and creating at least one fracture at the tip of a perforation tunnel, injection parameters and effects such as outflow rate and, in the case of multiple perforation tunnels benefiting from such cleanup, distribution of injected fluids along a wellbore are enhanced. Following detonation of a charge carrier, a second explosive event is triggered within a freshly made tunnel, thereby substantially eliminating a crushed zone and improving the geometry and quality (and length) of the tunnel. In addition, this action creates substantially debris-free tunnels and relieves the residual stress cage, resulting in perforation tunnels that are highly conducive to injection under fracturing conditions for disposal and stimulation purposes, and that promote even coverage of injected fluids across the perforated interval.

Abstract: Disclosed is a casing conveyed perforating system and methods for externally perforating a wellbore and casing. The perforating system is attached to the outside of the casing and is conveyed along with the casing when it is inserted into the wellbore. The perforation may be accomplished using two groups of charges, which are contained in protective pressure chambers, however, may use only one group of bi-directional charges. Each pressure chamber may be positioned radially around the outside of the wellbore casing. The pressure chambers form longitudinally extending ribs, which conveniently serve to center the casing within the wellbore. One group of charges may be aimed inward in order to perforate the casing, while the other group of charges is aimed outward in order to perforate the formation.

The firing assembly comprises a firing head for transferring ballistic energy to the perforating device, said firing head having a detonator and a plurality of ballistic charges, said detonator coupled to at least one of said first gun assembly and said second gun assembly a remote telemetry device for sending a detonation signal, a transmission medium for transmitting said detonation signal to said firing head, and a receiving device for receiving said detonation signal and a processor for interpreting said detonation signal and activating said detonator.

Abstract: Disclosed is a device and method for externally perforating a well-bore casing. The perforating apparatus is attached to the outside of the casing itself and is conveyed along with the casing when it is inserted into the well bore. The perforation is accomplished using two groups of charges which are contained in protective pressure chambers which are arranged radially around the outside of the wellbore casing. The pressure chambers form longitudinally extending ribs which conveniently serve to center the casing within the well bore. One group of charges is aimed inward in order to perforate the casing. A second group is aimed outward in order to perforate the formation. In an alternative embodiment, only one group of bi-directional charges is provided.

Abstract: A system and method provide for the modeling of a virtual call center for PSTNs in specified geographic locations. The system includes a user interface through which basic configuration and forecast information may be input for one or more PSTNs. Based on the information provided through the interface, various financial and engineering rules are employed to identify an optimal system configuration and to provide cost and revenue information with regards for that system. In configuring the optimal system, a number of fault and failure modes may be taken to account.
