Within the activities we perform for our clients we assist them in the negotiation and drafting of contract of different nature, such as service and work contracts, lease contracts, drilling, compression, seismic, and in general most of the contracts required for the regular activities of oil and gas companies. In some cases we also participate as members of the bidding committees of our clients. Also while working in PDVSA and its affiliates, our attorneys actively participated as members of bidding committees in such companies.
