| 20140262346 | METHOD OF INSTALLATION OF FLEXIBLE BOREHOLE LINER UNDER ARTESIAN CONDITIONS - An apparatus and method for facilitating eversion of a flexible liner down a borehole when an artesian head condition is producing a rate of water flow out of the top of the borehole. A bypass pipe channels artesian flow, moving upward in the borehole and/or well casing, past an everting flexible liner to a wellhead fixture. Artesian flow arriving at the wellhead fixture is pumped away to ameliorate resistance to liner eversion otherwise presented by the water flow. A heavy mud may be disposed inside the everting liner further to promote its downward eversion past the artesian flow. | 09-18-2014 |
| 20140262347 | METHOD FOR SEALING OF A BOREHOLE LINER IN AN ARTESIAN WELL - A method for sealing a flexible liner that has been emplaced in a borehole manifesting artesian water flow. The upper end of the liner is closed with a plug, and a mud tube is extended from the plug down to a small volume of mud at the bottom end of the liner. The pressure in the liner interior is increased according to the weight of the mud column in the mud tube. Pressure in the liner interior can be regulated by allowing mud to move up and down in the mud tube, and by adding or withdrawing water from the closed liner interior. | 09-18-2014 |
| 20140318813 | Temporary Support for Electric Submersible Pump Assembly - The need to have the housing of an ESP suspended by the discharge flange to allow room for downhole thermal expansion in a situation where there is no surface access to the lower end of the ESP when the discharge flange is bolted up is addressed by building the ESP on a support that is removable downhole without intervention. A controlled electrolytic material or CEM can be used or other materials that meet the structural support requirement for the ESP and then after a predetermined time lose their capacity to support leaving the ESP suspended by its discharge flange and capable of growing under thermal loading. | 10-30-2014 |
| 20150101828 | Tube Forming Device - A technique facilitates the plastic deformation of tubing to a desired size and shape. The technique enables deformation of tubing, such as a coiled tubing end, in a manner which facilitates installation of a tubing connector. A tubing forming device is used in cooperation with a tubing injector. The tubing injector moves the tubing through a die of the tubing forming device in a linear direction so as to deform the tubing to a desired shape and/or size. | 04-16-2015 |
| 20150122510 | Subterranean Room Conduit Conveyor Assemblies and Methods for Extending Conduit from a Subterranean Room - Subterranean room conduit conveyor assemblies are provided comprising a conveyor operatively aligned with a guide assembly, the guide assembly operatively aligned with a subterranean well head. Methods for extending conduit from a subterranean room to within a well extending from the room to within the earth surrounding the room are provided, the methods comprising operatively aligning a conveyor assembly with the well head of the well, feeding coiled conduit to the conveyor assembly, and conveying the conduit from the assembly into the well head of the well from the room. Well clean out nozzles are provided as well. | 05-07-2015 |
| 20160032696 | Metal Patch System - An apparatus, method and system repair wellbore casing. In one embodiment, an expandable casing patch system for a wellbore includes a casing patch deployment apparatus. The casing patch deployment apparatus includes a shaft having a frontward end and a rearward end as well as a thruster and a main expansion swage disposed on the shaft. The casing patch deployment apparatus also includes an anchor disposed on the shaft. The anchor is disposed frontward of the main expansion swage. In addition, the casing patch deployment apparatus includes a front expansion swage disposed frontward of the anchor and attached to the shaft. The front expansion swage has a diameter less than a diameter of the main expansion swage. The expandable casing patch system also includes an expandable casing patch. | 02-04-2016 |
| 20160097262 | Morphing Tubulars - A hydraulic fluid delivery tool for morphing a tubular downhole and a method of morphing a tubular downhole. The tool has spaced apart annular elastomer seal assemblies which operate by application of a piston against each elastomer to create a seal against the tubular. A first hydraulic fluid delivery line delivers fluid at a first pressure to operate the pistons. A second hydraulic fluid delivery line delivers fluid at a second pressure, lower than the first, to a location between the seals to morph the tubular and act on a second face of each piston to assist in maintaining the seal. | 04-07-2016 |
| 20160097263 | Morphing Tubulars - A pressure intensifier for morphing tubulars downhole. An elongate mandrel defines an inner bore, being co-axially located within an elongate hollow outer cylindrical body to form a co-axial annular bore therebetween. Pistons are mounted upon the mandrel with each piston having an annular fluid facing face extending across the annular bore, with fluid communication between the inner bore and the annular bore to act upon each face. Stops are located on an inner surface of the outer cylindrical body to limit travel of each piston. A morph fluid is located in the annular bore between an opposing face of a first piston and a first stop, with the first stop having delivery ports to deliver the morph fluid at a greater pressure than the pressure of fluid delivered through the inner bore. | 04-07-2016 |
