Abstract
This is an overview of the design and development of steamfield plant and pipework. The production system comprises 5 separation plants each fed by a group of production wells. Initially supplying HP and IP steam, the plants are designed for eventual derating to IP. Production wellheads feed individual two phase pipelines. Detailed study of pipeline supports achieved a reduction in pipeline costs. Two phase silencers have been developed to meet noise limits. The separated water is reinjected using a pumped system to wells near the boundary of the field.
