20090255687 | Sealing Between Alignable Windows for Lateral Wellbore Drilling - Sealing may be provided between alignable windows for lateral wellbore drilling. A method for use with a lateral wellbore includes the steps of: positioning a swellable seal material between a closure device and a housing of a window assembly; swelling the seal material to thereby prevent fluid transfer through a window formed in a sidewall of the housing; and then installing the window assembly in a parent wellbore. A lateral wellbore system includes a window assembly with a window formed through a sidewall of a generally tubular housing, and a swollen seal material preventing fluid transfer through the window. A window assembly includes a generally tubular housing having a window formed through a sidewall of the housing, a closure device having another window formed through a wall of the closure device; and a swellable seal material which prevents fluid transfer between the windows. | 10-15-2009 |

20090269611 | METAL-COATED STEEL STRIP - A steel strip having a coating of a metal alloy on at least one surface of the strip is disclosed. The metal alloy contains aluminium, zinc, silicon, and magnesium as the major elements. The metal alloy also contains strontium and/or calcium and unavoidable impurities and optionally other elements that are present as deliberate alloying elements. The concentration of magnesium is at least 1 wt. % and the concentration of (i) strontium or (ii) calcium or (iii) strontium and calcium is greater than 50 ppm. | 10-29-2009 |

20120088115 | CORROSION PROTECTION WITH AL / ZN-BASED COATINGS - Red rust staining of Al/Zn coated steel strip in “acid rain” or “polluted” environments can be minimised by forming the coating as an Al—Zn—Si—Mg alloy coating with an OT:SDAS ratio greater than a value of 0.5:1, where OT is the overlay thickness on a surface of the strip and SDAS is the measure of the secondary dendrite arm spacing for the Al-rich alpha phase dendrites in the coating. Red rust staining in “acid rain” or “polluted” environments and corrosion at cut edges in marine environments can be minimised in Al—Zn—Si—Mg alloy coatings on steel strip by selection of the composition (principally Mg and Si) and solidification control (principally by cooling rate) and forming Mg | 04-12-2012 |

20110268984 | METHOD OF CONTROLLING SURFACE DEFECTS IN METAL-COATED STRIP - A method of controlling “rough coating” and “pinhole-uncoated” surface defects on a steel strip coated with a aluminum-zinc-silicon alloy. The alloy has 50-60% wt Al, 37-46% wt Zn and 1.2-2.3% wt Si. The method includes heat treating the steel strip in a heat treatment furnace and thereafter hot-dip coating the strip in a molten bath and thereby forming a coating of the alloy on the steel strip. The method is characterized by controlling the concentration of (i) strontium or (ii) calcium or (iii) strontium and calcium in the molten bath to be at least 2 ppm. | 11-03-2011 |

20130059086 | METAL-COATED STEEL STRIP - A hot dip method of forming an Al—Zn—Si—Mg alloy coating on a strip is disclosed. The method includes controlling the conditions in the molten bath to minimise the top dross layer in the molten bath. In particular, the method includes controlling top dross formation by including Ca and/or Sr in the coating alloy in the bath. | 03-07-2013 |

20140102710 | MULTILATERAL BORE JUNCTION ISOLATION - A junction can be isolated from fracturing pressure using a liner extending from a one bore through a junction into a lateral bore, where at least a portion of the liner is retrievable from the lateral bore prior to completion of wellbore construction. The junction may be temporarily isolated from high pressure, such as high pressure from a fracturing stimulation process. Part of the liner can be retrieved using a disconnect mechanism or technique. | 04-17-2014 |
20140102716 | MULTILATERAL BORE JUNCTION ISOLATION - A junction can be isolated from fracturing pressure using a liner extending from a one bore through a junction into a lateral bore, where at least a portion of the liner is retrievable from the lateral bore prior to completion of wellbore construction. The junction may be temporarily isolated from high pressure, such as high pressure from a fracturing stimulation process.

20100071905 | Pressure Relieving Transition Joint - A method of completing a wellbore having a branch wellbore extending outwardly from a window in a parent wellbore is provided. The method comprises positioning a tubular string in the window, wherein the positioning comprises deflecting the tubular string from the parent wellbore into the branch wellbore. The method also comprises providing a particulate barrier outside and against the tubular string proximate the window, the particulate barrier substantially excluding transport of particulate matter from the branch wellbore into the parent wellbore outside of the tubular string through the window. The method also comprises the tubular string passing fluid into the tubular string proximate the window from a formation proximate to the window while substantially excluding transport of particulate matter from the formation proximate to the window into the tubular string. | 03-25-2010 |
20100212913 | Drilling and Completion Deflector - A tool assembly is provided. The tool assembly comprises a drilling deflector and a completion deflector, the completion deflector coupled to the drilling deflector. | 08-26-2010 |
