Development Geological Advisor; Geomodeler focused

The Development Geological Advisor will be responsible for a dual role in geomodelling and development geology to support the Vaalco team. They will create geologically reasonable static models by integrating interpretations and data from the geoscience team (seismic horizons, petrophysical rock properties, geological interpretations and depositional models, etc.), evaluate and modify existing static models. The Development Geological Advisor will work in collaboration with subsurface team (geoscientists, other geomodeller(s), simulation engineer(s) and reservoir engineers) to build reservoir simulation models in support of the company’s field development plans.

In a development geology capacity, they will be responsible for the evaluation and integration of geological, geophysical, engineering and production data to develop a detailed geological understanding of Vaalco’s reservoirs/fields while working closely with area engineers and geoscientists.
