Abstract
An advanced blowout preventer that includes an arrester section and a shear section. The arrester section includes a number or arrester rings that are shaped to extend downwardly. The shape of the arrester rings allows the force of gas flowing out of the well to assist in closing the rings. The arrester section may have a number of arrester rings that cooperate to significantly reduce fluid from flowing in the annulus between a section of drill pipe and the blowout preventer. The advanced blowout preventer may also include a shear section. The shear section is configured to engage and shear a section of pipe using induction.
Claims22
An arrester section comprising,
- a first arrester extending downwardly towards a wellhead;
- a second arrester extending downwardly towards the wellhead, said second arrester positioned above and in-line with the first arrester;
- and
- a motor connected to said first arrester, said motor configured to open said first arrester when energized.
An advanced BOP that comprises,
- an arrester section;
- a shear section;
- and
- a gripping section;
- wherein the gripping section is positioned closest to a well head, followed by the shear section, and then the arrester section.
An advanced BOP comprising,
- an arrester section that includes at least one downwardly extending arrester ring;
