Abstract

Many times, explorationists believe that once they have a gravity/magnetic survey, they don't need any more. Does that hold for seismic data as well? Of course not. Today, increasing seismic resolution is becoming the norm. Similarly, higher resolution gravity and magnetic data should be acquired as a play concept advances from reconnaissance to delineation. Even 4-D applications can be utilized in some situations. Table 1 describes the gravity and magnetic techniques that can be used as a resource evaluation program progresses. Each type of application requires different data resolution. Survey instruments and software tools are available to meet all these specifications, but the cost can vary substantially. Use this table to help plan or license the data and technology that fit your need.
