20150308221 | METHOD OF PROVIDING A BARRIER IN A FRACTURE-CONTAINING SYSTEM - The present invention relates to a method of providing a barrier in a fracture-containing system, comprising: i) Providing a treatment fluid comprising: a) a base fluid; b) an elastomeric material, wherein said elastomeric material comprises at least one polymer capable of crosslinking into an elastomer, and c) at least one crosslinking agent; ii) Placing the treatment fluid in a fracture-containing system; iii) Allowing the elastomeric material to crosslink with itself to form a barrier in said fracture-containing system; wherein the elastomeric material and/or the crosslinking agent are of neutral buoyancy with regard to the base fluid. The invention is contemplated to having utility not only in the oil-drilling industry but also in the plugging of fractures in sewer drains, pipelines etc. | 10-29-2015 |
20150128443 | On-Site Drying And Curing Of Paint Systems Using Catalytic Infrared Radiators - A method is disclosed for the on-site surface coating of a structure, the structure being part of a construction including a plurality of structures, the method including the steps of: a) applying one or more layers of a coating system on-site to at least a part of the structure, b) arranging at least one gas catalytic infrared emitting unit in a position so that the infrared radiation is adapted for heating the one or more layers of the protective coating system on-site and c) irradiating the coated surface with infrared radiation emitted by the at least one gas catalytic infrared emitting unit on-site. The method allows the drying and/or curing of the one or more layers of the coating system to be accelerated. | 05-14-2015 |

20120279710 | INJECTION DRILL BIT - A device for drilling a hole in a well tubular and for subsequent injection of a fluid or fluid mixture into an annular space or formation surrounding the well tubular. The device comprises a housing and a drill bit assembly arranged inside the housing. In the drill bit assembly, a drill bit with cutting edges and grooves extending along its outside surface, is arranged. The device further comprises rotation means being capable of rotating the drill bit assembly and a fluid supply for supplying a fluid or fluid mixture to the grooves of the rotating drill bit. A seal is surrounding the drill bit and capable of sealing the device against the inner surface of the well tubular. | 11-08-2012 |
20120273238 | JACKING UNITS AND BELLOWS FOR DOWN HOLE INTERVENTION TOOLS - A device and a method for positioning a tool in a well tubular. The device comprising a housing having jacking arm assemblies with extendable jacking arms for fixating the device inside the well tubular. The device further comprising a tool connected to the housing and bellow assemblies comprising inflatable means for positioning the device substantially in the centre of the well tubular. By deflating the inflatable means and simultaneously activating the jacking arms the device is pushed in a direction which is substantially perpendicular to the well tubular. | 11-01-2012 |
