Abstract: A method and apparatus for inserting a small diameter continuous hydraulic conduit or capillary tube down a well bore is presented. The methods and apparatus allow either the injection of chemicals to enhance production of oil and gas, or to provide a conduit for production up through the small diameter tubing in marginal wells, into a hanger below a well valve to permit its removal from below the valve if the valve should be required to be closed and its reinsertion without pulling the tubing from the well bore.

Abstract: The present invention relates to an apparatus and method for using that apparatus to orient a perforating gun or system to minimize or eliminate the damage which may be caused to exterior control conduits, conductors or devices, or to adjacent interior well control lines, conduits or tubing by attaching the perforating system to a device which has a resilient cam or guide which engages a slot formed on the interior of a specially fabricated tubular member attached at a spaced distance from the perforating systems blast and which is so oriented as to permit the attachment of the lines or conduits or devices in the opposite radial direction from the blast of the perforating system.

Abstract: Methods and apparatuses to determine the temperature profile of a pressurized wellbore using a fiber optic cable and an anchor are disclosed. Furthermore, a pressurized wellhead spool that couples to a standard Christmas tree structure on a well head to facilitate the injection of fiber optic cable into an oil and gas well is disclosed. The wellhead spool is portable and may be connected to fiber optic cable already located at the site, for quick connection to on-site instrumentation. A method of using the apparatuses disclosed to measure wellbore temperature at multiple depths of investigation is also disclosed.

Abstract: Fiber optic cable is daisy-chained between a plurality of wells. Rather than terminating a piece of fiber optic cable down each well, the fiber optic cable is disposed down, then back up a plurality of wells at once. Using the fiber optic cable, a parameter of interest is measured in each of the wells. The parameter may be temperature which can be sensed by sending optical signals down the fiber optic cable, then measuring the backscattered signals. In one implementation, steam injected into one or more wells is adjusted based upon the parameter readings.

Abstract: In a well an instrumentation line can be introduced down the well bore by a control line having at least a portion outside of intermediate casing and set in cement slurry between the intermediate casing and the surrounding rock and reaching to a zone of interest. A primary member accepts the distal end of the control line at the end of the intermediate casing. A secondary member has a terminal control line (sealed at its far end) attached on its outer surface. When in place, the secondary member extends into and through the zone of interest. When the secondary member is lowered through the primary member, its top end is lowered onto the bottom end of the primary member. Couplings engage and angularly orientate so that the top of the terminal control line couples to and seals with the distal end of the control line to form a conduit through which a fibre optic instrumentation line can be threaded.

Abstract: A fiber optic instrumentation line is introduced down a hydrocarbon (oil) well bore 12 by control line 16 formed by pressure tubing conduit fixed on the outside of intermediate casing 14 and set in cement slurry 21 between casing 14 and surrounding rock 13 and reaching to the hydrocarbon production zone 15. Hollow primary member 18 accepts distal end of control line 16 at the end of casing 14. Secondary member 22 having sealed terminal control line 27 on its outer surface is lowered through primary member 18 to zone 15, automatically angularly aligning and engaging respective top and bottom end couplings 24 and 20, sealing together a respective top and end of terminal control lines 27, 16 forming a continuous, high pressure, fiber optic receiving tube, from well head 10 to well bottom. Alternatively, two lines 16 linked by loop 26 provide a continuous control line returning to the surface.

Abstract: Methods of draw-down and build-up testing on existing production wells are disclosed. The testing may be accomplished without removing the production tubing string from the well. The production of the well is shut down and then a coiled tubing test string is run down into the production tubing string. The coiled tubing test string includes a coiled tubing string, a tester valve carried by the coiled tubing string, and a test packer carried by the coiled tubing string. The test packer is set within one of the casing bore and the production tubing bore above perforations which communicate the casing bore with a subsurface formation. Draw-down and build-up testing of the subsurface formation can then be accomplished by opening and closing the tester valve to selectively flow well fluid up through the coiled tubing string or shut in the coiled tubing string.
