20120234551 | System and Method For Drilling A Well That Extends For A Large Horizontal Distance - Method and apparatus for extending the horizontal distance through which wells can be drilled. A horizontal tubular is used to convey a drillstring from a drilling rig toward a target location and a mud return line and pump on the surface is used to pump drilling mud returning from the bit back to the drilling rig. | 09-20-2012 |
20120266801 | MOORING SYSTEM FOR FLOATING ARCTIC VESSEL - A mooring system for a floating vessel such as a drilling unit is provided. The floating vessel has a platform for providing drilling, production or other operations in a marine environment, and a tower for providing ballast and stability below a water line in the marine environment. The mooring system generally includes a plurality of anchors disposed radially around the tower along a seabed, and a plurality of mooring lines. Each mooring line has a first end operatively connected to the tower, and a second end operatively connected to a respective anchor. Each mooring line further comprises at least two substantially rigid links joined together using linkages. Each joint is at least five meters in length. The mooring system is capable of maintaining station-keeping for the vessel greater than about 100 Mega-Newtons such that operations may be conducted when the marine environment is substantially iced over. | 10-25-2012 |

20140308080 | Arctic Telescoping Mobile Offshore Drilling Unit - A system and method of drilling oil and gas wells in arctic or other environments having adverse conditions. A marine hydrocarbon operations structure may comprise a caisson body having a top surface which defines an opening and a shaft positioned within the opening. The shaft has an engagement member positioned on the external surface of the shaft. A lower jack house system is constructed and arranged to change the vertical position of the shaft through interaction with the engagement member. An operations platform supported by the shaft. | 10-16-2014 |
20150101522 | Arctic Rapid Disconnect and Reconnect Floating Driller - A system, including: a floating drilling unit; a buoyancy hull plug releasably connected to the floating drilling unit; mooring lines with first ends secured to a seafloor and second ends secured to the buoyancy hull plug; and a riser that is collapsible through a water column, wherein the buoyancy hull plug supports the riser and the mooring lines while disconnected from the floating drilling unit. | 04-16-2015 |
20150211337 | Arctic Walker for Hydrocarbon Exploration - A marine vessel for hydrocarbon exploration and methods of utilizing the same. In some embodiments, the vessel is enhanced with deployable and adjustable land propulsion mechanisms controlled by an active system to maintain position when on top of a drifting ice floe, water propulsion devices connected to the vessel hull capable of station-keeping in open water and/or within broken sea ice, sufficient power and flexibility to enable riding an ice floe, and at least one deployable ice hole cutter to open a channel through the ice floe. | 07-30-2015 |

20150083662 | ANAEROBIC SUSPENDED GROWTH TREATMENT OF CONTAMINATED WATER - A system may include a reactor, in which an anaerobic environment exists, that includes a slurry of at least contaminated water and a mixed bacterial culture of facultative bacteria and anaerobic bacteria. The mixed bacterial culture may be suspended within the slurry. The contaminated water may include contaminants associated with a non-metal, a metal, or a metalloid. The mixed bacterial culture may react with the contaminated water to reduce or remove the contaminants from the contaminated water to create a treated slurry. The reactor may output the treated slurry. The system may also include a filtration device to receive the treated slurry; remove, from the treated slurry, the mixed bacterial culture and the contaminants, reduced or removed from the contaminated water, to create treated water; and output the treated water. The system may also include an aeration device to add dissolved oxygen to the treated water, and output the treated water. The system may also include a reaction device where iron or aluminum salts are added to remove phosphorous, selenite, arsenate, or other contaminants which adsorb onto iron or aluminum oxyhydroxide solids. The system may also include a filtration device to remove the solids from the water, and output the treated water. | 03-26-2015 |
