Patent number: 8123888Abstract: A technique facilitates construction of high temperature fiber reinforced polymer oilfield tubulars. The technique comprises a method of combining a fiber material and a high temperature thermoset resin to create a high performance composite material. The composite material is formed into an oilfield tubular that can be used in a variety of downhole applications. The method of combining the high performance materials with low modulus, high temperature coating materials during the manufacturing process produces composite tubular products that can survive prolonged exposure to deleterious well fluids in high temperature and high pressure downhole environments.Type: GrantFiled: April 28, 2009Date of Patent: February 28, 2012Assignee: Schlumberger Technology CorporationInventors: Ahmed Hammami, Todd Yakimoski, Bernadette Craster, J.R.

Patent number: 7757775Abstract: A technique distributes localized stress acting on a tubular. The tubular is formed with an inner layer and an outer layer that is compliant relative to the inner layer. A force distribution material is disposed between the inner layer and the outer layer to spread any concentrated loads acting against the tubular. The compliant nature of the outer layer causes it to distort against the force distribution material when acted on by a concentrated external load. The outer compliant layer and the force distribution material cooperate to isolate and protect the inner layer from displacements of the surrounding subterranean material.Type: GrantFiled: September 28, 2007Date of Patent: July 20, 2010Assignee: Schlumberger Technology CorporationInventors: Ahmed Hammami, Scott Jacobs, Bernadette Craster, Todd Yakimoski, J.R.

Patent number: 7451813Abstract: A technique facilitates release of pressure from a well, and/or surface treating lines, via a bleed-off mechanism. The bleed-off mechanism is in fluid communication with a flow path extending from a wellhead valve or wellbore and designed for connection with a vacuum truck. The bleed-off mechanism can be opened to enable venting of trapped pressure from the wellbore and/or flow path. The bleed-off mechanism is also designed to contain any liquid that escapes during release of the trapped pressure. Once the pressure is relieved, the vacuum truck can be used to clean out fluid from the wellbore and/or surface treating lines without exposure to excess pressure.Type: GrantFiled: March 4, 2008Date of Patent: November 18, 2008Assignee: Schlumber Technology CorporationInventor: Mark Alexander Day
