f Luna-Hera Lacinia 3D case history: solving complex structures in presence of heavy operative constraints by combining different acquisition techniques

The Luna - Hera Lacinia - 3D survey (Offhore Calabria, Southern Italy) covers an area of about 180 square Kms and represents an excellent example of the integration of deep, shallow marine and land 3D acquisition techniques . The survey has been acquired as a "full 3D" on an area characterised by a complex marine and land morfology with serious land operating constraints and complex subsurface structures at a commercially acceptable cost. The target of the survey was to define the structural setting of the miocene reservoirs of Luna and Hera Lacinia gas-fields in order to optimize their development stage. Considering the difficulties, the survey initially required an adequate planning of the various stages of operation and following this a numerical simulation to evaluate its effectiveness .
