摘要： A method and apparatus for selecting an optimum VCO from an array of VCOs is disclosed. Each VCO in the array has an output range and a limit. In one embodiment, a search set of VCOs is designated as all VCOs in a system. The limit is compared to a tuning value which corresponds to a desired calibration frequency. The comparison divides the array of VCOs into a searched set and a non-searched set. The process is repeated until the non-searched set comprises only one VCO. In another embodiment, the VCOs are ordered such that there is a middle VCO. A VCO in the middle of the array is selected. The limit of the middle VCO is compared to a tuning limit. Based on the comparison, another VCO is selected. The process repeats N times, where N is the logarithm, base 2, of the total number of VCOs to be searched. at the end of the search, an optimum VCO will be found.

摘要： A method for completing a well in a single trip, including: inserting a completion tool assembly into the well, the completion tool assembly having a gravel packing assembly and a service tool assembly slidably positioned substantially within an interior cavity in the gravel packing assembly; removably coupling the service tool assembly and the gravel packing assembly; plugging at a first location, whereby fluid is blocked from flowing through the interior channel; diverting fluid blocked by the plugging at the first location through a first fluid flow path to an exterior of the completion tool assembly; circulating a gravel pack slurry through the completion tool assembly; plugging at a second location, whereby fluid is blocked from flowing through the interior channel; diverting fluid blocked by the plugging at the second location through a second flow path that reenters the interior channel at a location distal of the first and second plugging locations; and circulating a filter cake stimulating fluid through the well completion assembly.

摘要： Authorization verification systems and methods are described that determine whether an authorization check is to be performed at a point of sale or other point of control, and, if the authorization check is to be performed, that check the authorization and that store a retrievable record of the authorization check. The system receives authorization information for an individual that is indicative of the individual's authorization to purchase a product or service, to enter a location, to attend an event, or to otherwise participate in an encounter whose access is limited to authorized individuals. In one embodiment, authorization for making a purchase is limited to individuals above an age threshold, and the authorization verification system receives information relating to the individual's age via an electronic scanning of a driver's license or other identification card, or by other methods, and uses the birth date information to calculate the customer's current age. The current age can be displayed on an existing display of a point-of-sale device or other display. A record of the authorization can be stored and can subsequently be retrieved to verify that an authorization check for the encounter was carried out.

摘要： The present invention provides a bi-directional ball seat and method of use. In at least one embodiment, the present invention provides a fluid control system that includes a radial protrusion that can be selectively engaged and disengaged upstream and/or from a ball seat. For example, a ball can be placed in a passageway, engaged with a downstream ball seat, and the radial protrusion radially extended into the passageway distally from the seat relative to the ball. A reverse movement of the ball is restricted by the active radial movement of the radial protrusion into the passageway. The control system can be used to control a variety of tools associated with the well. Without limitation, the tools can include crossover tools, sleeves, packers, safety valves, separators, gravel packers, perforating guns, decoupling tools, valves, and other tools know to those with ordinary skills in the art.
