| A technique facilitates cutting of a conveyance or other member passing through a tubular system, such as a landing string and/or a subsea test tree. The technique utilizes a pair of cutter blades pivotably coupled together at a pivot which may be located adjacent a pair of cutting edges. The pair of cutter blades is located in a body which has a passage sized to enable movement of certain tools and conveyances therethrough. The pair of cutter blades is connected to a piston actuated mechanism which may be selectively actuated to move the cutting edges toward each other and across the passage extending through the body. When the cutter blades are in an open position, the tools and/or conveyance may be moved through the cutter body along the passage. | ||||||
| 263 | Torsional shearing of oilfield tubulars | US13564892 | 2012-08-02 | US09316080B2 | 2016-04-19 | Eric Dale Larson |
