Patent number: 9091138Abstract: The current application discloses methods and systems for generating high pressure dual phase mixture. In some embodiments, the methods and systems involve mounting a dual phase mixture generator on a transportable platform wherein the dual phase mixture generator comprises a mixing chamber connected with at least a first inlet, a second inlet, and a first outlet. A first container and a first pump are also mounted on the transportable platform wherein the first pump is operably connected with the first container. The transportable platform and the mounted equipments are then deployed at a wellsite. A base fluid is pumped into the first inlet under high pressure, and a gas is pumped into the second inlet under high pressure. The base fluid and the gas is combined in the mixing chamber to generate a high pressure dual phase mixture, which is then discharged via the outlet.Type: GrantFiled: January 27, 2014Date of Patent: July 28, 2015Assignee: Schlumberger Technology CorporationInventors: Brian Goddard, Roger Keese

Patent number: 8002049Abstract: A method of preventing or treating lost circulation during the drilling of a well comprises the addition, at concentration ranging between about 0.5 and 6 pounds per barrel, of water-dispersible fibers having a length between about 10 and 25 mm, for instance glass or polymer fibers, to a pumped aqueous base-fluid including solid particles having an equivalent diameter of less than 300 ?m. The base-fluid with the solid particles can be the drilling fluid or a small-volume pill specially pumped for curing lost circulation.Type: GrantFiled: December 3, 2007Date of Patent: August 23, 2011Assignee: Schlumberger Technology CorporationInventors: Roger Keese, Trevor Munk, Raafat Abbas, Erik Nelson, Benoit Vidick
