The current buoyant attitude about prospects for the floating production system market sometimes overlooks the important sub-class of tension leg platforms. The author explains why the interest already engineered by TLP concepts should be nurtured. 95104507

The deep waters of the Atlantic margin West of Shetland pose sixeable problems for oceanographers and offshore engineers alike. Offshore Engineer takes a peek behind the scenes at some of the most ambitious wmmercial oceanographic studies yet undertaken. 95lQ4500 Equatlons for predlctln the cetane number of die sel fuels from their physlcal properts es Ladommatos, N. and Goacher, J. Fuel, Jul. 1995, 74, (7), 1083-1093. Twenty-two equations for predicting the cetane number of diesel fuels were tested for accuracy by comparing the predicted values for ~500 fuels with the measured values. All the equations and measured values were taken from the literature. It was found that the predictive capability of certain equations was high: several could predict the cetane nun&et with a standard error of <2. It is concluded that it is unlikely that the standard error can be reduced significantly below 1.5, because the measured cetane numbers are themsleves subiect to exoerimental error. The eauations were unable to predict accurate1 * the cetGe number of untypical’diesel fuels, such as vegetable oils an(r diesel blends containing alcohols. This was expected, since these empirical equations were cons&ted from databases for typical diesel fuels only. 95/04509 Giant steps out Cottrill, A. Offshore Engineer, Jun. 1995, 12-13. Billed as ‘the tallest construction ever moved by man on the surface of the earth’, the Troll Gas platform has now made the transition from inshore completion site to the offshore location where it will serve for the next fifty to seventy years.
95104512 In situ combustion In Canadlan heavy oil reservoirs Moore, R. G. et aL, Fuel, Aug. 1995, 74, (8), 1169-1175. The paper reviews the laboratory combustion performance of different heavy oil and oil sand reservoir samples, and discusses the field performante of some of the in situ combustion projects which have bezn or continue to be operated in Canada. Abnormal behaviour (deviation from classical concepts of combustion) encountered in the field and in the laboratory are interpreted in the light of the combustion kinetics developed by the In Situ Combustion Research Group at the University of Calgary. The results are used to suggest design considerations for successful field projects. 95104513 Modelllng of In situ combustion for Turklsh heavy crude oil fields Kok, M. V. and Ocalan, R. Fuel, Jul. 1995, 74. (7), 1057-1060. Different models were used to determine the possibility of in situ combustion applications for heavy crude oil fields in south-east Turkey. In the first approach a one-dimensional mode1 was developed, in which the frontal advance concept is combined with mass and energy balance e uations with certain boundary conditions, limitations and assumptions. %le recovery histories of three oil fields were determined; the highest recovery was obtained in field 2 with dry combustion and m field 1 with wet combustion, depending on the reservoir characteristics. From the recoveries obtained the profitability of the in situ combustion applications was calculated. In the second appraoch, a computer program was developed to ap ly the oil-recovery-volume-burned correlation method to the same oil fie Pds. 95104514 Offshore Enalnserlna - An Introduction Mather, A.

Offshore engineering encompasses a considerable number of very specialized and often completely unrelated disciplines. They may be categorised into three basic activities, namely Construction, Production and Reservoir Engineering and this book has been written, not as a defiiitive manual but as a general introduction to exolain the essential features of these core activizes. The material wntaine’d wihtin this publication will provide the new recruit to the industry with a basic appreciation of what is a relatively complex subject, whilst at the same time providing the more experienced individuals with a broader perspective of activities outside their own particular speciality. 95104515 Steam-assls&d gravlty dralnage In oil aand rsssr. volrs uslna a comblnatlon of vettlcal and horlrontal wells Rose, P. E.&d Deo, M. D. Fuel, Aug. 1995, 74, (8). 1180-1184. New algorithms are presented for steam-assisted gravity drainage (SAGD) in oil s&d reservoirs using vertical injectors-pro&ceti and ve&l injec; tar-horizontal uroducers. A vertical-well aleorithm was develooed and extended to account for steam chamber wnfiiement due to adjaceht vertical wells. The production rates in the vertical-well processes were found to be significantly lower than in the horizontal-well broccsses, owing to the near-well congestion henomenon. This observation was consistent with the results of physuz *af model studies conducted by other investigators. A new model for the SAGD process using vertical injectors and horizontal producers was also developed and the results were compared with those of SAGD with a horixontal-well pair. 95lQ4516 Subsea Industry comes of age Lindland,Ii.
