Patent number: 6422312Abstract: In a multiple well completion, spaced apart production packers isolate independent production zones from one another. In each isolated production zone, a side pocket mandrel with a full opening bore has lengthwise extending side by side elongated pockets (1) for receiving a static pressure measuring instrument or tool (static pressure pocket); (2) for providing a venturi flow passageway (flow passageway pocket); and (3) for receiving a differential pressure measuring tool (differential pressure pocket). The static pressure measuring tool and the differential pressure measuring tool or instrument are commonly connected by a data coupling means to a single electrical conductor line which is strapped to the string of tubing and extends to the earth's surface for transmission of control signals and data signals between the earth's surface and the various side pocket tools.Type: GrantFiled: October 13, 1999Date of Patent: July 23, 2002Assignees: Retrievable Information Systems, LLC, Schlumberger Technology CorporationInventors: Leroy C.

Patent number: 5996687Abstract: A variable flow control device having a substantially cylindrical housing with a valve element connected to an inner surface thereof. The valve is movable between an open position and a closed position in the bore. One or more flow control orifices are located in the valve element for controlling the flow of fluids through the housing when the valve element is in the closed position. A drive mechanism is also connected to the valve element for controlling the size of the one or more flow control orifices. As such, a full bore variable flow control device is provided that controls the flow of wellbore fluids without permanent reduction of the internal bore of the production tubing. By closing the flapper valve and selecting the size of the variable orifices, total control of the production flow of the wellbore can be achieved. By opening the flapper valve, full bore wireline operations to the bottom of the well can be performed.Type: GrantFiled: June 19, 1998Date of Patent: December 7, 1999Assignee: Camco International, Inc.Inventors: Ronald E.

Patent number: 5861562Abstract: A flow measurement having a substantially cylindrical housing with a valve element connected to an inner surface thereof. The valve is movable between an open position and a closed position in the bore. A secondary flow passageway is formed in the housing and extends along the longitudinal axis of the housing. A first end of the secondary flow passageway is in fluid communication with the bore below the valve element. A flow measuring device is located near a second end of the secondary flow passageway for measuring the rate of fluid flow therethrough. The housing is adapted to be connected at each end thereof to well tubing. The present invention provides a flow measurement mandrel that diverts the production flow the secondary flow passageway by closing a hydraulically operated flapper valve and routing the fluid or gas through the a venturi flume in the secondary flow passageway for flow measurement. After monitoring flow rate, the flapper valve is re-opened and full bore production is achieved.Type: GrantFiled: June 19, 1998Date of Patent: January 19, 1999Assignee: Camco International Inc.Inventors: Ronald E.
