Abstract:
1. A drilling operation optimization unit for a reservoir at a wellsite, comprising: a base model unit for producing a base model of the reservoir and providing a base pre-calculation of the reservoir using the base model; a reservoir stress unit for producing a three dimensional stress model of the reservoir and providing a stress pre-calculation of the reservoir using the stress model; a model consolidation unit operatively connected to the base model unit and the reservoir stress unit and receiving the base model and the three dimensional stress model therefrom, the model consolidation unit merging the base model with the three dimensional stress model into a consolidated model and merging the base pre-calculation and the stress pre-calculation into a consolidated partial calculation of the reservoir using the consolidated model; storage device coupled to the model consolidation unit to receive and store the consolidated partial calculation; an input to receive a plurality of potential wellbore trajectories from a user; and a trajectory unit comprising a processor operatively connected to the model consolidation unit, the storage device, and the input, the trajectory unit determining at least one wellbore property based on the user selected plurality of potential wellbore trajectories and the consolidated partial calculation.
