Patent number: 7805988Abstract: A formation tester system with a tester tool comprising two or more functionally configured flow lines. The two or more functionally connected flow lines cooperating with one or more pumps and cooperating valves direct fluid to and from various axially disposed sections of the tester tool for analysis, sampling, and optionally ejection into the borehole or into the formation. The functionally connected flow lines extend contiguously through the sections of the tester tool. The functionally configured flow lines, cooperating with the one or more pumps and valves, can also direct fluid to and from various elements within a given tester tool section. Manipulation of fluid flows within the tester tool, as well as analysis, sampling and/or ejection operations, can be varied with the tester tool disposed in the borehole using appropriate commands from the surface of the earth.Type: GrantFiled: January 24, 2007Date of Patent: October 5, 2010Assignee: Precision Energy Services, Inc.Inventors: Bryan William Kasperski, Margaret Cowsar Waid, Stanley Robert Thomas, Jr., Dennis Eugene Roessler

Publication number: 20100206561Abstract: An apparatus (100) for controlling the connection speed of first and second downhole connectors (316, 146) in a subterranean well. The apparatus (100) includes a first assembly that is positionable in the well. The first assembly includes the first downhole connector (316) and a first communication medium. A second assembly includes the second downhole connector (146) and a second communication medium. The second assembly has an outer portion and an inner portion. The outer portion is selectively axially shiftable relative to an inner portion, such that upon engagement of the first assembly with the second assembly, the outer portion of the second assembly is axially shifted relative to the inner portion of the second assembly allowing the first and second downhole connectors (316, 146) to be operatively connected to each other, thereby enabling communication between the first communication medium and the second communication medium.Type: ApplicationFiled: February 18, 2009Publication date: August 19, 2010Applicant: HALLIBURTON ENERGY SERVICES, INC.Inventor: William Mark Richards

Publication number: 20100200225Abstract: A multi-functional completion tool which may be lowered into a wellbore coupled to a length of tubing, and then utilized to test various lengths of the tubing at pressure. The tool may also function as a positive plug, may be used to set a packer, and is also useable as a tubing self-filling tool. Various retention elements are disposed within the tool and configured to release at predetermined pressures, or within predetermined ranges of pressure, thereby transforming the tool from a first configuration to a second configuration depending on the desired function. The tool may use a flapper mechanism to regulate passage of fluids through the housing, and a piston and/or flow tube may also be utilized to lock the flapper in an open or closed orientation within the housing.Type: ApplicationFiled: April 25, 2010Publication date: August 12, 2010Applicant: DOWNHOLE AND DESIGN INTERNATIONAL CORP.Inventors: ADEL GHOBRIAL ABDELMALEK, S.
