Publication number: 20140110101Abstract: A technique facilitates the use of polymer materials in a downhole environment via utilization of a coating that can be applied to the polymer material. The methodology enables formation of a coating that sufficiently bonds with an underlying base structure of polymer material to withstand the harsh environment encountered in a downhole application. Additionally, the coating may utilize reactive chemistries to further protect the polymer material against the ingress of deleterious fluids while located in the downhole environment. Well tubulars formed of coated polymer are also described.Type: ApplicationFiled: December 10, 2013Publication date: April 24, 2014Applicant: SchlumbergerTechnology CorporationInventors: Bernadette Craster, Ahmed Hammami, Timothy G.

Patent number: 8439106Abstract: A technique facilitates the logging of hot, subterranean environments with a variety of logging tools. Logging tools with temperature limit ratings may be employed in environments that would otherwise be detrimental to operation of the logging tool due to the heat. The logging tool may be protected through placement of the tool at a desired location within a non-metallic flask. The logging tool also is surrounded with an insulating material and/or a material with a high heat of fusion disposed within the non-metallic flask to increase the time span for operating the logging tool in the hot, subterranean environment.Type: GrantFiled: March 10, 2010Date of Patent: May 14, 2013Assignee: Schlumberger Technology CorporationInventors: Ahmed Hammami, Todd Yakimoski, Bemadette Craster, John Richard Anthony Pearson

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: 8065929Abstract: An environmental mechanical test apparatus includes a pressure generation source and an isolation cylinder in fluid communication with the pressure generation source. The test apparatus further includes a pressure containment cell configured to receive a test specimen, an environmental chamber disposed about the pressure containment cell, and a load frame operably associated with the pressure containment cell. The pressure containment cell is in fluid communication with the pressure generation source and the isolation cylinder and includes a viewing window.Type: GrantFiled: May 5, 2009Date of Patent: November 29, 2011Assignee: Schlumberger Technology CorporationInventors: Todd Yakimoski, Bernadette Craster, Scott Jacobs, Ahmed Hammami

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: 7669482Abstract: A technique enables testing of a wellbore tubular under simulated well conditions. The wellbore tubular is mounted in a fixture for testing. Controllable systems are used to subject the wellbore tubular to a variety of predetermined conditions simulating potential downhole environments. The controllable systems include manipulators able to place the wellbore tubular under predetermined load, displacement, temperature, and pressure conditions.Type: GrantFiled: September 28, 2007Date of Patent: March 2, 2010Assignee: Schlumberger Technology CorporationInventors: Scott Jacobs, Ahmed Hammami, Todd Yakimoski

Publication number: 20090277625Abstract: Described herein are compositions for reducing or preventing the degradation of equipment and articles exposed to hydrogen sulfide present in high concentrations in subterranean environments (e.g., oil and gas wells). The compositions are composed of a thermoplastic resin, a thermosetting resin, or a combination thereof, and at least one compound that interacts with hydrogen sulfide from the subterranean environment. In certain aspects, the compositions are coated on the article of interest. In other aspects, the composition is used to manufacture the article and, thus, is integrated throughout the article.Type: ApplicationFiled: February 24, 2009Publication date: November 12, 2009Applicant: SCHLUMBERGER TECHNOLOGY CORP.Inventors: YUN BAI, TIMOTHY G.J.

Patent number: 7593101Abstract: Apparatus and methods are described for observing samples at non-ambient temperatures and pressures. One apparatus comprises a cell body having a fluid flow-through passage and a light passage intersecting the fluid flow-through passage at an adjustable light pathlength fluid analysis region; first and second light-transmissive windows in the light passage, each window having at least one crystal axis aligned longitudinally with a longitudinal axis of the window, the windows having opposed, spaced apart, substantially flat surfaces defining the adjustable light pathlength fluid analysis region, the first window having a first window holder and the second window having a second window holder, the first window rotationally isolated from the first window holder, the second window rotationally coupled to the second window holder, the first window holder able to gradually move the first window and thus adjust the light pathlength; and first and second light polarization filters.Type: GrantFiled: April 10, 2007Date of Patent: September 22, 2009Assignee: Schlumberger Technology CorporationInventors: Todd Yakimoski, Scott Jacobs, Ken Sitko, Ahmed Hammami, Terry Sopkow, Craig Borman
