Abstract

The southwest corner of Jonah field was targeted by Cabot Oil and Gas Corporation for an exploration program to extend the limits of established production. A reprocessed aeromagnetic survey was initially used as a cost-effective method to image this area (the Yellow Point area). However, the aeromagnetic survey did not provide the necessary resolution to convince Cabot to drill a well on their acreage. Subsequently, Cabot acquired a 16.1-mi2 (42-km2) high-resolution, three-dimensional (3-D) survey to evaluate their acreage and define the southwestern intersection of the two faults that form the trap at Jonah field. The Yellow Point area of Jonah field is a region of complex, structural relationships and outstanding gas production. Cabot used the high-quality, 3-D seismic data in combination with available well control and aeromagnetic data to delineate the updip structural limits of Jonah field. Based on this study, a high-risk, high-reward prospect was identified as a southern extension of the Yellow Point area. A wildcat well was drilled on this high-potential prospect with negative results. The wildcat well encountered a normally pressured Lance section outside of the main Jonah fault block.
