"A production facility is being considered for the extraction of oil from the Kopanoar Field in the Canadian Beaufort Sea where water depths are approximately 60 metres (200 ft). Various types of structures are being contemplated. These include primarily two different types, namely a standard artificial island with berms and caissons, and a gravity structure with berms for ice load protection. A major obstacle to the design of either type of facility is a very soft upper seabed clay stratum approximately 6 metres (20 ft) thick. This feasibility design study addresses primarily the aspects of an artificial island stability related to the foundation soil conditions. The objectives were to obtain a geotechnically sound and economically feasible conceptual design, and to evaluate other possible designs that could be constructed with equipment presently available to Dome Petroleum Ltd. in the Beaufort Sea. These objectives have been met. ... The conclusions of this feasibility study may be summarized as follows: 1. The artificial island would be unstable if founded on 6 m (20 ft) of very soft seabed clays unless it was constructed slowly over a period of many years. 2. Vertical drains used below the entire island to reduce consolidation time would be uneconomical for this project. In addition, an extended construction period would be required to allow time for sufficient strength gain in the very soft seabed clays. 3. Partial removal of the very soft seabed clays would also necessitate an extended construction period. 4. Key soils and field testing data are required to quantitatively assess the potential benefits of dynamic consolidation on stability. 5. Fill displacement methods of construction may result in sand intrusions within the very soft seabed soils or displacement of these soils. Field test data are required to evaluate this construction procedure. 6. The optimum design would involve removal of the very soft seabed clays from approximately berm crest to berm crest, beneath the island core. Additional soils data are required to determine the precise extent of removal. 7. The potential for berm toe instability is not believed to be a serious impediment to the feasibility of the artificial island, but needs further investigation. 8. The findings reported herein are based on the limited soil data currently available in the region of the proposed Kopanoar Island. When a precise location has been selected and site-specific geotechnical testing carried out, it may be possible to optimize the design of the island. The present study is based on a realistic interpretation of the regional conditions, but because of the limited data currently available it is necessarily conservative"--Executive summary.
Reservoir Characterization is a collection of papers presented at the Reservoir Characterization Technical Conference, held at the Westin Hotel-Galleria in Dallas on April 29-May 1, 1985. Conference held April 29-May 1, 1985, at the Westin Hotel—Galleria in Dallas. The conference was sponsored by the National Institute for Petroleum and Energy Research, Bartlesville, Oklahoma. Reservoir characterization is a process for quantitatively assigning reservoir properties, recognizing geologic information and uncertainties in spatial variability. This book contains 19 chapters, and begins with the geological characterization of sandstone reservoir, followed by the geological prediction of shale distribution within the Prudhoe Bay field. The subsequent chapters are devoted to determination of reservoir properties, such as porosity, mineral occurrence, and permeability variation estimation. The discussion then shifts to the utility of a Bayesian-type formalism to delineate qualitative ""soft"" information and expert interpretation of reservoir description data. This topic is followed by papers concerning reservoir simulation, parameter assignment, and method of calculation of wetting phase relative permeability. This text also deals with the role of discontinuous vertical flow barriers in reservoir engineering. The last chapters focus on the effect of reservoir heterogeneity on oil reservoir. Petroleum engineers, scientists, and researchers will find this book of great value.
