LWD Maps Path to New Pay on Old Field

Publication Date: 07/01/2011

The Yme field, offshore Norway, was shut down in 2001 for reasons including increasing water-cut, high operating costs, and relatively low oil prices. It has since become the first abandoned field on the Norwegian Continental shelf to be re-developed. Talisman Energy executed a drilling campaign that included high-angle producers with long sections in thin reservoir sands. The PeriScope real-time bed boundary mapper was used to help geosteer a horizontal section within the high-permeability pay zone. The wellbore reached a total distance of 511 m MD within the target sand—exceeding its objective by more than 100 m, and achieving a net-to-gross (NTG) ratio of 92.5%. The well remained between 0.7 and 2.2 m TVD of the upper boundary, enabling Talisman to maximize production of attic oil.
