GeolOil provides a stable simulation grid builder for the simulators Eclipse, Stars, and More. It computes reliable and consistent Corner Point Geometry grids (CPG) that are imported into the simulators. It computes accurate jumps through faults, making the necessary adjustments so cell top surfaces passes exactly through the well tops without spikes, artifacts or over-smoothing.

The GeolOil Production Scheduler builds the simulator include file that specifies which cells are open to production through the 3D cell well navigation paths. For this, 3D deviation directional survey trajectory path files, and the events that opened and closed the perforations in calendar dates need to be loaded. Not all simulators and static modeling packages provide this must have feature.

GeolOil's engine to build 3D geo-cellular static models uses an exclusive variogram-free, multi-point geostatistical realization algorithm that produces believable geological scenarios and shapes. No more worries to fit horizontal variograms, change a realization seed, or to think about how suitable is a stationary process hypothesis for the reservoir.

The image below shows an example. Notice how a "seahorse", S shape style comes out naturally. Try to achieve this using Sequential Gaussian Simulation (SGS) by fitting variogram models with only 22 wells. What horizontal variogram azimuth would you use? How many realizations would you try to get even close to this pattern?
