    Abstract: A drill-through spool body sleeve assembly comprises a test sleeve removably installed within a drill-through spool body having a bore with the terminal ends of the outer diameter of the test sleeve sealingly engaging the bore wall. The sleeve assembly also comprises a wear bushing removably installed in the bore between the bore wall and the test sleeve. The test sleeve is of sufficient thickness to pressure test the spool body outlets, ports, and valves before drilling and production. The test sleeve seals the bore from the outside of the spool body during the pressure testing. After the pressure tests are completed, the test sleeve is removed from the spool body, leaving the wear bushing in place. The wear bushing protects the bore wall, outlets, ports, and valves while allowing equipment such as drilling and wellhead equipment to pass through the spool body. After the well is drilled and the casing strings are installed, the wear bushing is removed from the spool body to allow the installation of the production tubing and production hanger within the spool body.

    Abstract: A subsurface signal transmitting apparatus including an insulation coupler, a carrier device for mounting the telemetry instrumentation, and a by-pass system for avoiding pressure build-up either above or below the apparatus. The insulation coupler includes a housing member having a central opening defined by an interior surface extending in the longitudinal direction and a mandrel member having an exterior surface spaced from the interior surface of the housing member to provide a gap or clearance with an insulating bonding material occupying the clearance. The surfaces are oriented so that when the coupling is in tension at least a portion of the two surfaces experience interacting forces towards each other in the longitudinal direction of the coupling and in event of failure of the bonding material, the mandrel member is unable to withdraw from the housing member. The by-pass system includes a by-pass tube which extends through central openings of the insulation coupler and carrier device and provides for electrically insulating one end of the assembly from the other but allows for pressure equalization via a fluid passage-way. The carrier device has a cylindrical body forming external channels for concealing instruments about is circumference.

    Abstract: A method and associated apparatus continuously optimizes reservoir, well and surface network systems by using monitoring data and downhole control devices to continuously change the position of a downhole intelligent control valve (ICV) (12) until a set of characteristics associated with the nullactualnull monitored data is approximately equal to, or is not significantly different than, a set of characteristics associated with nulltargetnull data that is provided by a reservoir simulator (32). A control pulse (18) having a predetermined signature is transmitted downhole thereby changing a position of the ICV. In response, a sensor (14) generates signals representing, nullactualnull monitoring data. A simulator (32) which models a reservoir layer provides nulltargetnull data. A computer apparatus (30) receives the nullactualnull data and the nulltargetnull data and, when the nullactualnull data is not approximately equal to the nulltargetnull data the computer apparatus (30) executes a nullmonitoring and control processnull program code which changes the predetermined signature of the control pulse to a second and different predetermined signature. A new pulse having the second predetermined signature is transmitted downhole and the above process repeat until the nullactualnull data received by the computer apparatus (30) is approximately equal to the nulltargetnull data.

    Abstract: In the field of tools for use in boreholes, an apparatus (10) includes a pump (11) for circulating fluid under pressure in a wellbore (12). A control device (13) controls the speed of the pump (11). A conduit (17) interconnects the pump and the wellbore (12). Within the wellbore a downhole transducer (21) that is capable of detecting changes in the pressure of fluid at a downhole location and generating signals indicative thereof. A processor (23) generates actuator commands in dependence on the generated signals. One or more actuators (24) is operable to activate at least part of a downhole tool in dependence on a said actuator command. A modulating valve (26) is capable of modulating the pressure of fluid in the conduit. A remote transducer (27) that may be eg. at a surface location, is capable of detecting pressure of fluid in the conduit at a location remote from the downhole transducer (21). The control device causes the pump to generate one or more digital acoustic signals in the fluid, the wave forms of which are detectable by the downhole transducer (21). The modulating valve (26) is capable of generating digital or analogue wave forms in the fluid. In operation the control device sends control signals via the fluid that are detected by the downhole transducer (21). Consequently the processor (23) causes actuation of one or more tools. Following correct actuation the modulating valve (26) generates signals in the form of pressure changes in the fluid. The remote transducer (17) detects and displays such signals, to indicate at a surface location whether deployment of the tool has occurred successfully.
