Generated production profiles with 2 years longer plateau & COP by early gas lift and water shut off (Mbal, Prosper, Shaphir and VIP dynamic models). Added reserve 0.8 MMstb by Decline Curve Analysis in Andrew & Cyrus fields. EOR multiple contact miscible displacement gas injection study, that identified additional resource 2.5 MMstb in Farragon field (1D compositional and black oil model VIP,Mbal, EOR Prosper & Gap)
2005
Landmark Halliburton KL Malaysia
History matched D18 field Eclipsel. Duland & Tiong Ke-Pong fields review (Mbal, well test, DCA)
1980 - 2004
BP Venezuela, Total, Statoil and more...
During this time I held several positions in different companies and worked on several projects in the Latin American Region. My responsibilities and achievements included the development of gel treatment applications to improve water & gas injection profiles in water injection wells in the El Furrial field Venezuela (EOR), well tests, reservoir evaluation and many more.
