  • Patent number: 6269880
    Abstract: A system for removing solids from a well bore and reclaiming the well bore fluid. A work string is disposed within the well bore. The system includes a gas separator, connected to a return line from the well bore, for separating the gas component from the well bore fluid, and wherein the gas separator has a first outlet for exiting the gas component and a second outlet for exiting the well bore stream. Also included is a solids separator, connected to the second outlet, for separating the remainder of the well bore fluid into a first stream containing the solids and a second stream containing the well bore fluid. The solids separator may be located longitudinally below the gas separator so that a hydrostatic head pressure aids in feeding the well bore fluid to the solids separator. The system further includes a cuttings box connected to the solids separator, with the cuttings box being configured to receive the solids from the solids separator.

  • Patent number: 6269458
    Abstract: A computer system for diagnosing and isolating faults in the computer system. A first value is written from the processor using the bus a first address within the address space of a diagnostic state machine. The value is latched in a first register and written from the first register to a second address in the memory. By reading a second value from the memory at second address, the processor compares the second value to the first value to indicate an error if they are different.

  • Patent number: 5652915
    Abstract: A computer system for controlling the mode of operation of a data cache. When a DMA state machine detects a DMA cycle to a memory block, the machine interrupts the processor so the processor sets a new value of the DMA state to control the mode of cache operation associated with the block.

  • Patent number: 4967853
    Abstract: A gauge carrier which is tubing conveyed with a wireline retrievable gauge system for more effectively evaluating reservoir potential and whether it is economically feasible to complete the well and place it into production. The gauge carrier and method of this invention provides effective solutions to problems which arise when endeavoring to measure and accurately record bottom hole pressure during temporary flow tests as well as on a permanent hookup on a well completion. The gauge carrier can be run on the tubing or drillstem above or below a packer as a part of a temporary or permanent completion and the gauge assembly can be retrieved by the use of a wireline after the well completion process has been completed.
