• Reservoir engineer for development of the El Merk field since the 2009 project sanction. • Evaluated large SCAL and PVT programs, which have been integrated into simulation models. The complex fluid system included saturated and undersaturated oils, as well as gas condensates and lean gas fields. • Worked with multi-disciplinary team to rebuild full-field models as new drilling information became available. Matched the models to extensive database of well tests and interference data, and updated the field development plan.• Evaluated potential benefits of miscible and immiscible WAG flooding.
