Major Projects

Prior to joining D&M, Larasati worked as a development geologist with ConocoPhillips. During her time with ConocoPhillips in Houston, Larasati added reserves, optimized oil recoveries, identified new development opportunities through reservoir characterizations, resources assessment, and field development planning, and conducted well placement and data acquisition of carbonates and clastic reservoirs in several areas within the Permian Basin in New Mexico, United States. She built 3–D geocellular models for reservoir simulation for the purpose of secondary recovery optimizations and development plans.

Before transferring to Houston, she worked within a multidisciplinary team at ConocoPhillips Indonesia to develop clastic fluvial deltaic reservoirs in the West Natuna Basin, Indonesia. She completed 3–D geocellular models based on geostatistical and deterministic models to characterize subsurface uncertainty in volumetric estimation and to identify sufficient reserves for a gas export agreement.
