Abstract

The Kingfisher field is located in Blocks 16/8a and 16/8d in the South Viking Graben 278 km (173 mi) northeast of Aberdeen. The field was discovered in 1972 by Shell/Esso well 16/8-1, which targeted a faulted anticlinal structure and encountered thin-bedded and poor quality reservoir sandstones within a dip closure mapped at the Base Cretaceous unconformity (BCU) level. The field was first appraised in 1984 by well 16/8a-4, which encountered a better quality Brae sandstone member reservoir interval to the northwest of the discovery well. Further appraisal wells 16/8a-8, 16/8a-9, and 16/8a-9z confirmed the presence of good quality reservoir sands across the central and western parts of the field. The exploration and appraisal drilling established the fluid contacts in the field and also critically helped to delineate the transition from good quality axial to poorer quality distal facies within the outer part of the Brae submarine fan system. Furthermore, data from development well drilling and reservoir behavior during production of the field have provided insights into the static and dynamic connectivity within the Brae sandstone member reservoirs as well as provided additional insights into the controls on reservoir quality and productivity. This chapter aims to build on the previous published information on the field by providing further details on the geological characteristics of the Brae sandstone member reservoirs within the Kingfisher field and how the reservoir architecture and properties, in addition to aquifer connectivity, have determined well and reservoir production performance and behavior.
