Well Planning and Design

Many surface constraints can make well planning a challenging task. Given the reservoir properties and the well trajectory constraints, CRYSTAL provides the necessary tools to optimize the hydrocarbon recovery while minimizing the costs and drilling risks.

Upscaling

As the seismic grids have an areal resolution corresponding to the size of the seismic bin (typically 12 -25 meters) and a vertical resolution of 1-3 meters, the resulting geocellular grids used in the geophysical and geologic tasks have a size varying between 50 to 500 million cells. These grids can be built and used in CRYSTAL but are one order of magnitude larger than the grids commonly used by other geomodeling software and two orders of magnitudes larger than the grids used by reservoir simulators -hence the need for upcaling the grids and their attributes. CRYSTAL provides a multitude of upscaling methods including: Arithmetic, Harmonic, Geometric, Arithmetic-Harmonic, Harmonic-Arithmetic, Arithmetic-Geometric, Geometric-Arithmetic, Harmonic-Geometric, Geometric-Harmonic and Renormalization which is very adapted to upscaling very quickly permeability models.
