20080252881 | HIGH-PRESSURE CROSS-POLAR MICROSCOPY CELLS HAVING ADJUSTABLE FLUID PASSAGE AND METHODS OF USE - 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. | 10-16-2008 |
20090188666 | Method And System For Completing A Well - A technique facilitates the detection and measurement of formation properties with various measurement devices, such as logging tools. The technique comprises locating a standard tubular in a well such that the standard tubular extends to a zone of interest with respect to a logging procedure. A transparent tubing is attached to the standard tubing so as to extend along the zone of interest. Additionally, a protective material is directed to the region adjacent the transparent tubing to protect the transparent tubing from detrimental contact with deleterious well fluid. | 07-30-2009 |
20090200013 | WELL TUBULAR, COATING SYSTEM AND METHOD FOR OILFIELD APPLICATIONS - 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. | 08-13-2009 |
20090236091 | FIBER REINFORCED POLYMER OILFIELD TUBULARS AND METHOD OF CONSTRUCTING SAME - 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. | 09-24-2009 |
20090277625 | Compositions For Reducing Or Preventing The Degradation Of Articles Used In A Subterranean Environment And Methods Of Use Thereof - 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. | 11-12-2009 |

20090314107 | Environmental Mechanical Test Apparatus - 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. | 12-24-2009 |
20110042075 | LOGGING SYSTEM AND METHODOLOGY - 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. | 02-24-2011 |
20120055242 | DOWNHOLE SAMPLING - A reservoir sampling apparatus comprising at least one probe adapted to provide a fluid flow path between a formation and the inner of the apparatus with a heating projector adapted to project heat into the formation surrounding the probe and a controller to maintain the temperature in the formation below a threshold value. | 03-08-2012 |
