Three-dimensional visualization for well placement and geosteering: Njord Field, offshore mid-Norway
Publikováno v:
Geological Society, London, Petroleum Geology Conference Series. 6:1487-1506
Njord is a structurally complex Lower Jurassic oil field located on the Halten Terrace, offshore mid-Norway. The field was discovered in 1986 and has been under production since 1997. The field is produced by a combination of depletion and crestal ga

Atlantic white cedar, Chamaecyparis thyoides (L.) B.S.P., swamps have decreased in area by up to 98% and the ecosystem is listed as globally threatened. The decline is thought to have resulted from drainage, which was followed by conversion to agricu

Fiber optic Bragg gratings packaged in long gage configurations are being used to measure static and dynamic strain in structures and structural models to monitor structural health and predict damage incurred from a seismic event. These long gage sen

Previously, the results of embedding multi-axis fiber gratings into adhesively bonded joints were discussed. This paper presents more information on the testing of the adhesive joints and techniques employed to successfully embed a fiber grating sens

Fiber grating strain sensors offer a means to monitor the health of highways and bridges as well as a means to monitor vehicular traffic patterns and critical data such as speed, weight, and classification of vehicle types. This paper overviews recen

Most fiber grating sensor technology that has been developed to support strain sensing involves the measurement of axial strain. Fiber grating sensors are however capable of monitoring transverse as well as axial strain. This paper reviews a series o

For many structural applications it is highly desirable to be able to measure two or more axes of strain at a single point. In many cases one dimensional strain measurements may be insufficient to fully characterize events or lead to erroneous predic

Fiber optic sensors have the potential to be used in the very hostile environments necessary for advanced aerospace platforms. This paper reviews some of the key issues associated with the implementation of distributed fiber optic sensors in harsh en

For very high-speed events, such as ballistics testing, strain measurement speed is not limited by the response of the fiber grating sensor, but rather the demodulation system used. This paper focuses on a current 10 kHz fiber grating demodulator use
