  • Subsea production systems have successfully demonstrated their overall reliability, and have established a proven track record over the past 30 years of field experience. Current trends in their configuration from large, heavy, multiwell integrated drilling template and production/injection manifold systems to small, light-weight, {open_quotes}mini template{close_quotes} systems or clustered well manifolds with individual satellite wells-essentially a cost reduction trend-are expected to continue throughout the remainder of the decade. System configuration and equipment technology trends in the 1990s are now improving the profitability and capability of subsea production systems.
  • A West German consortium is beginning deepwater tests on a subsea oil loading system (SOLS) that the developers claim will improve the likelihood for early production of arctic fields. A prototype system was completed last year after a two-year development project. Sea tests were to begin off Norway in March. The present design provides for a 6000 b/d loading capacity. The system is designed for water depths up to 350 meters, but the aim is to expand to much greater depths. This system is particularly attractive for ice areas and other regions where the laying of pipelines is not feasible.
  • Selected nonproprietary technology related to permafrost behavior, Arctic drilling problems, cement requirements, logging and testing concepts, casing and wellhead installation, specialized completion equipment, and permafrost protection methods are discussed. Part 1 defines and analyses the effects of thaw subsidence, excess ice, external freezeback, gas-hydrate decomposition, and lithology on soil behavior around the casing string as evidenced in field tests performed at Prudhoe Bay. The studies show that thaw subsidence can be attributed to four mechanisms - excess ice melting, consolidation with fluid expulsion, pore-pressure reduction, and stiffness reduction.
  • When designing Arctic well completions, operators must gather and evaluate data on the basic lithological, mechanical, and thermal properties of the surrounding permafrost in order to anticipate problems caused by thaw subsidence, freezeback, and hydrate decomposition. Although logging appears to be the most practical data-retrieval system, the unavailability of special logging tools for permafrost applications may sometimes make coring and field testing necessary for complete evaluation. Part 4 of this well-completion series concentrates on the most important permafrost properties for consideration in direct-measurement programs and provides guidelines for selecting a data-retrieval system for a given location.
