  • Publication number: 20010045250
    Abstract: An attachment between a monitoring device and an innerliner of a tire includes the use of an epoxy adhesive that bonds the monitoring device directly to the inner surface of the innerliner of the tire. The innerliner is first roughened in a manner that provides a roughened portion of the innerliner without removing the entire thickness of the innerliner. The entire thickness of the innerliner is not removed because the innerliner is preferably more than {fraction (1/16)} of an inch thick. The thickness of the innerliner allows the rigid cured epoxy to bond the monitoring device to the inner surface of the innerliner while allowing the innerliner to flex with the tire so as to not break the seal between the rigid epoxy and the innerliner. The monitoring device is preferably located at a low flex area of the tire to help avoid the problem of the innerliner flexing.

  • Publication number: 20010045285
    Abstract: A mudsaver valve with bi-directional snap action in opening and closing the valve. The mudsaver valve is adjustable for different mud weights and is easily assembled and disassembled in the field. Furthermore, elevated pressure from below is readily transmitted past the valve seat, so that the standpipe pressure of the well can be determined through the valve when the pumps are stopped and still connected to the drillstring. One embodiment of the mudsaver valve also contains a mechanism whereby the valve may be locked open by an accessory tube whenever a pipe gets stuck and becomes inaccessible, thereby permitting wireline operations through the valve so that the pipe may be freed.

  • Publication number: 20010045286
    Abstract: A tieback connector comprises a passive lower locking system and an active upper locking system to exert a positive locking force on the connection between a production riser and a high pressure wellhead. The tieback connector is comprised of an outer housing which carries lower locking dogs, upper locking dogs and a piston. The piston is located above the lower end of the production riser and controls the movement of the outer housing. As the piston is stroked the outer housing cams the lower dogs into grooved profile in the wellhead housing. As the piston is stroked further the upper dogs exert a force onto the production riser that locks the riser to the wellhead housing.

  • Publication number: 20010045288
    Abstract: The present invention provides a drop ball sub that may be used to drop a large ball having an outer diameter larger than the inner diameter of a restriction in the wellbore such as the running tool used to run a first casing string through a second casing string. A smaller ball is used to control dropping of the large ball. The smaller ball has an outer diameter smaller than the restriction. The drop ball sub of the present invention may be used to operate any downhole tool that would benefit by receipt of a large ball. By dropping a larger ball, in one use of the invention larger valves can be controlled in the float equipment that provide a larger fluid flow path. A larger fluid flow path reduces surge pressure and enables the system to handle more debris. The present invention provides a system that preferably provides for a diverter tool above the running tool and a diverter tool below the running tool.

  • Publication number: 20010045289
    Abstract: A wellbore casing formed by extruding a tubular liner off of a mandrel. The tubular liner and mandrel are positioned within a new section of a wellbore with the tubular liner in an overlapping relationship with an existing casing. A hardenable fluidic material is injected into the new section of the wellbore below the level of the mandrel and into the annular region between the tubular liner and the new section of the wellbore. The inner and outer regions of the tubular liner are then fluidicly isolated. A non hardenable fluidic material is then injected into a portion of an interior region of the tubular liner to pressurize the portion of the interior region of the tubular liner below the mandrel. The tubular liner is then extruded off of the mandrel.

    Abstract: A method of stimulating coalbed methane production by injecting gas into a producer and subsequently placing the producer back on production is described. A decrease in water production may also result. The increase in gas production and decrease in water production may result from: (1) the displacement of water from the producer by gas; (2) the establishment of a mobile gas saturation at an extended distance into the coalbed, extending outward from the producer; and (3) the reduction in coalbed methane partial pressure between the coal matrix and the coal's cleat system.
