Abstract
This presentation focuses on how new prospectivity has been identified and developed in a quite mature area on the Norwegian Shelf. The area of interest was recently awarded to PL 559 in the APA 2009 licensing round. It is located at the Nordland Ridge in blocks 6608/10 and 6608/11 just east of several discoveries and fields. The area has previously been part of license PL 128 since 1986, but was stepwise relinquished over the last few years due to disappointing well results where many of the traditional prospects have been proved dry. In the current study the entire area has been interpreted on 3D seismic, which has been tied to nearby wells. Using a new play concept and integrating data we have identified multiple attractive prospects of high commercial value at several different target intervals which have all been proven to contain oil in discovery wells immediately to the west. Studies including pressure evaluation, fault seal studies and migration modeling have been performed to mature and de-risk the prospects. CSEM modeling confirmed that the prospectivity was feasible for de-risking using CSEM technology, and both proprietary CSEM data as well as published material has been used in order to de-risk the prospectivity further.
