Locating bypassed oil at the Alba field using time-lapse seismic

摘要

Maintaining the daily production rate, and hence prolonging the field life, of a mature asset is largely dependent upon locating and producing the oil that has been bypassed by the existing well stock. At the Alba field (Central North Sea, UK Continental Shelf [UKCS]), recent efforts to identify the bypassed reserves and subsequently optimize future well paths have focused on the use of dedicated time-lapse (4-D) seismic to better understand the field-wide variation in remaining oil thickness.
