Abstract: A system for determining the ability of a selected motor to function in a wellbore preferably includes an input device, a data storage device and a program. The program is preferably configured to determine an expected motor load based on motor input data and application input data. Using the expected motor load, the program determines a projected motor temperature increase. The program adds the projected motor temperature increase with the wellbore temperature to determine a projected operating temperature. The projected operating temperature is compared with the maximum recommended operating temperature of the selected motor, or a list of candidate motors, to determine the ability of the selected motor to function in the wellbore.

Abstract: Systems and methods are disclosed which provide upgrade information for a client computer. Detection of a current hardware configuration of the client computer is facilitated by: 1) reading serial presence detect (SPD) data from the client computer; 2) reading motherboard parameters from the client computer such as a manufacturer ID and product ID of the motherboard; and/or 3) identifying the SPD write-protect status of the SPD chip on the client computer. Additionally or alternatively, detection of the current hardware configuration may be facilitated by: 4) reading other OS data such as system name and/or operating system version, and/or 5) performing tests to determine certain computer characteristics such as memory utilization and/or CPU speed. In most cases, the information gathered is cross-referenced with a proprietary database of product specifications, to confirm the current hardware configuration of the client computer within specified parameters.

Abstract: An apparatus for producing fluid from a well intersecting a plurality of producing formations. The apparatus includes a pumping system lowered into the well on a production tubing. The well is separated into upper and lower production zones by a packer installed in the well. Fluid is communicated upwardly in the well from the upper zone through a first flow conduit and from the second zone through a second flow conduit. Fluid from both zones is combined and produced upwardly in a single stream. The amount of fluid produced from each zone can be determined with a flow meter which will measure the amount of flow produced from one or more of the zones.
