The tubular member has at least one cavity formed on an external surface. At least one housing is adapted to be insertable and extractable in the cavity without further tool disassembly. The housing has at least one electrical device such as a battery stack disposed within. In another aspect, sensors are disposed in the housing for measuring downhole parameters of interest including, but not limited to, annulus pressure and annulus temperature. A method of replacing an electrical device in a downhole tool, comprises removing a first housing containing the electrical device from a cavity on an external surface of the downhole tool, and installing a second housing containing a second electrical device in the cavity without disassembling the tool further.

  • Publication number: 20030136556
    Abstract: This invention provides a tubing hanger system which permits isolation of the production tubing from the electrical power cable, thereby isolating the electrical power cable from high pressures encountered in the production tubing. Further, the tubing hanger system enables pressure testing of the integrity of both the production and cable seals, without requiring disassembly of any components of the tubing hanger assembly or damaging the electrical power cable, in advance of high pressure operations. Specifically, the invention provides a tubing hanger assembly for use in a tubing head of a production well, and which provides for passage of production fluids from the production tubing mounted therebelow, through a central bore in the tubing head and through the tubing hanger assembly, while also providing isolation of the production tubing from an electrical power cable passing through the tubing hanger assembly.

  • Publication number: 20030066649
    Abstract: A subterranean well production system utilizes a single well to perform both hydrocarbon fluid production and water dumpflooding processes. The well has a primary wellbore that is communicated with first and second subterranean zones respectively containing hydrocarbon fluid and higher pressure water. A second, lateral wellbore extends from the primary wellbore and communicates with the first zone. A remotely controllable routing system, including a valved production tubing structure extending through the primary wellbore, is operable to (1) flow hydrocarbon fluid from the first zone to the surface via the production tubing and (2) simultaneously dumpflood water from the second zone into the first zone, via the production tubing, to increase the pressure within the first zone and thereby increase the hydrocarbon fluid production rate.

  • Patent number: 6543541
    Abstract: A method for controlling entry from a main bore of a casing into a lateral bore of a producing well which incorporates (i) means for surface-actuated flow control in the lateral bore (ii) a flow control means located in the casing adjacent to the lateral bore, and said method comprising the steps of: a) removing the flow control means when entry to the lateral bore is required, said flow control means having an internal passage allowing upward flow of produced fluid from the main bore and through said passage; b) mounting a locating nipple on the casing adjacent to the lateral bore; c) engaging the flow control means with the nipple to locate the flow control means in the casing; and d) providing diverter means in the casing which engages with and is orientable relative to the nipple and operates to guide entry to the lateral bore from above the nipple following removal of said flow control means.

  • Publication number: 20030010498
    Abstract: A device and method for delivering fracture fluid (e.g., erosive materials) into an oilfield wellbore while the well has wireline, coiled tubing, jointed tubing or any other apparatus encumbering the flow path of the erosive fluid that is being injected into the device. The device provides the ability to insert and remove equipment in the wellbore during fluid treatment while maintaining access to the full wellbore diameter. The invention also provides a method for delivery and positive, down-hole displacement of material (i.e., diverting material including, but not limited to buoyant ball sealers).

  • Patent number: 6457530
    Abstract: A monolithic pumping tree combining a bottom connection, production blow-out preventer section, flow tee section and top connection is cast so as to provide an access port extending downwardly through the side wall of the tree from its outer surface, to connect with either the central vertical bore of the tree or its horizontal bottom surface, thereby enabling coiled tubing to be inserted either into the tubing string bore or into the annulus between the tubing and production casing strings.

  • Patent number: 6422312
    Abstract: 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.
