Patent ID: 8448709

Claim:
A method for killing of an uncontrolled fountain from an offshore oil well comprising the steps of: a. providing a plurality of flow restricting rods, each of said flow restricting rods is sized to have a cross-section area from about 20 mm 2 to about 1,200 mm 2 , each of said flow restricting rods comprising a series of straight sections configured for assembly with each other to form together said flow restricting rod, b. forming a first flow restricting rod by assembling a first series of said straight sections one at a time to extend said first flow restricting rod from a sea surface to a well opening, continuing to assemble additional straight sections for lowering the first flow restricting rod of said plurality into said well so as to reduce a cross-sectional area of said well to cause a reduction of said uncontrolled fountain, c. forming a second flow restricting rod by assembling a second series of said straight sections to extend said second flow restricting rod from said sea surface to said well opening, continuing to assemble additional straight sections for lowering the second flow restricting rod of said plurality into said well and positioning said second flow restricting rod adjacent to said first flow restricting rod, whereby further reducing the cross-sectional area of said well causing a further reduction in said uncontrolled fountain, d. serially assembling additional straight sections to form further flow restricting rods to extend from said sea surface to said well opening, lowering said additional flow restricting rods of said plurality one at a time and positioning thereof in said well adjacent to each other to minimize said uncontrolled fountain in said well, and e. sealing off said well to permanently stop said uncontrolled fountain.
