Abstract
A method and system for simulating reservoir recovery include taking into account inaccuracies in well spacing due to wellbore positional uncertainty.
Claims19
A computer-implemented method of simulating reservoir recovery, the method comprising:
- receiving a request including input parameters, the input parameters comprising a description of a reservoir model, a description of planned wells, and one or more tool codes respectively corresponding to a survey tool error model;
- computing an ideal recovery for the reservoir model based on the planned wells;
- computing a simulated recovery for the reservoir model at least one time for each tool code, further comprising:
- computing a wellbore trajectory in the reservoir model taking into account wellbore positional uncertainty specified by the survey tool error model;
- and
- computing the simulated recovery from the wellbore trajectory;
- computing a simulated recovery loss from a difference between the simulated recovery and the ideal recovery;
- computing an average recovery loss for at least one tool code from the simulated recovery loss;
- and
- at least one of causing a display of the average recovery loss to be updated and causing the average recovery loss to be stored in a non-transitory computer readable medium.
