... Abstract As the drilling technology has advanced, recent deepwater developments and explorations are currently taking place in Gulf of Mexico, Brazil and West Africa where deeper reserves of oil have become more accessible. The study of the subsea soil (e.g. soil investigation, positioning...

... include teams and managers, as well as organisation-wide strategies and processes. Examples of organisation learning failures found during the study included: Observations of underlying issues not being investigated despite repeated failures Limited use of failure trend data Limited...

... Side-scan sonar "Hydra" is designed to produce acoustic images of the sea bottom surface. The investigation is carried out while a vessel is under way. "Hydra" locator is mechanically attached to the metal mount, which, in its turn, is attached to the hull with installed power supply and control...

... been responsible for stimulating research into several aspects of corrosion and environmental cracking associated with HPHT production. This paper details the investigation of production tubing coupling failures, which occurred during the retrieval of cold worked 25Cr duplex stainless steel production...

.... These field examples demonstrate that both methods, if carefully used, can yield almost identical radii of investigation derived from the entire test sequence and that the deconvolution technique can reveal additional reservoir information which may not be detected otherwise. pressure transient testing...

... transport. A significant amount of work has in the past decades been put into investigations to find the optimum viscous properties of the drilling fluid to obtain proper hole cleaning. Saasen 8 presented data showing that the frictional pressure loss over the cuttings bed in the annulus...

... have arisen from this investigation. Of interest was the observation that under schedule 7g5 conditions (BHCT 185º F), thickening time was longer at all concentrations than for similar Schedule 7g4 conditions (BHCT 165° F) and, as expected, for Schedule 8 conditions (BHCT 206°F). Since compressive...

... drilling and completion of a well is mainly influenced by the top of cement level supporting the 20″ or 18.5/8″ casing. Measurement of well compression effects can allow estimation of the top of cement level of this casing. compression investigation casing design cement level upstream oil...

... Abstract Components fail because they have been subjected to adverse conditions or they have some defect of design, material or construction. The reasons for carrying out a failure investigation should be carefully examined before embarking on what could possibly be a very expensive operation...

... Abstract The paper describes investigations presently being carried out at Heriot-Watt University into the dynamic behaviour of supply vessels moored to offshore installations. Physical testing was carried out using 1/100th scale models of supply vessels and specialised moorings in regular...

.... The main aspects to be investigated are the sensitivity of scattering techniques to relative refractive index, mean particle size, size distribution, shape, and particle particle size, size distribution, shape, and particle concentration. These investigations would help resolve practical questions...
