Survey design should provide an efficient and practical survey geometry that meets the required survey parameters. Therefore, we have to seek an optimal geometry, taking survey productivity and constraints into consideration. In a transition area, the types of sources and receivers are various and mixed depending on the environment. They are independently deployed, allowing high flexibility in geometries with various roll and shooting patterns such as blending methods. In this paper, we tried to optimize the geometry with several shooting methods, maintaining the required parameters whilst enhancing the survey productivity. We will review and discuss the results of this case study.
