Abstract: A whipstock is supported adjacent the lower end of a string during the drilling of the lateral. It has no integrated anchor. The BHA is delivered through the string that supports the whipstock. After a lateral is drilled the BHA is retracted and the support string is manipulated to advance the whipstock to a new location for proper orientation with a gyroscopic tool. The BHA is then advanced through the support string for drilling of another lateral in the same trip in the hole. The process can be repeated as many times as needed. Peripheral pads on the lower end of the whipstock push the lower end of the whipstock ramp to the borehole wall for proper tracking of the lateral. The laterals can be in open or cased hole and the support string can have circulation ports near the whipstock to cool the BHA in geothermal wells.

Abstract: An on-demand teleconferencing system and method for setting up an on-demand conference call in a telecommunications system having the Advanced Information Network (AIN) architecture with system signaling the number 7 (SS7) and a Public Switched Telephone Network (PSTN). A subscriber is assigned an on-demand conference call number. When that number is dialed into the PSTN, it is identified by the PSTN that the dialed number requires handling by the SS7. The SS7 links the dialed number to a conference allocation and control system (CACS) which is connected to a plurality of scalable bridge servers. The CACS selects bridge servers available to handle the conference call and based upon a selection criteria such as a peak load sets up the on-demand conference call in one of the selected bridge servers.
