II.1.5) Short description of the contract or purchase(s):

The contract is a non exclusive framework agreement with economic operator(s) to provide seismic data processing and reprocessing services to Chevron Romania Exploration and Production SRL and affiliated companies, including but not limited to Chevron Polska Energy Resources SP ZOO (hereinafter referred to as "company") for land-based exploration and production activities in Europe. Company will use the award criteria as stated in the framework agreement invitation to tender. Company's preferred outcome would be to award frame work agreement(s) to economic operator(s) who are capable of delivering all the required services.
