Well Performance Modeling In A Collaborative Well Planning Environment
First Claim
1. A method for well planning incorporating well completion design in a collaborative environment, comprising:
- specifying one or more wellpath parameters defining a wellpath to at least one target within an earth model stored in memory;
specifying one or more completion parameters defining a completion operation;
simulating the completion operations using the earth model based on the wellpath parameters and the completion parameters to generate a set of well performance measures;
determining whether the well performance measures are within defined well performance technical limits;
if the well performance measures are within the defined well performance technical limits, optimizing well placement within the earth model stored in memory in order to maximize an objective function; and
if the well performance measures are not within the defined well performance technical limits, adjusting one of the wellpath parameters, the completion parameters, and any combination thereof to generate adjusted parameters and repeating the simulating operations utilizing the adjusted parameters.

Abstract
Methods and systems are provided that may be utilized to make completion design an integral part of the well planning process by enabling the rapid evaluation of completion performance. This integration may include an earth model and may specify wellpath parameters, completion parameters, and other parameters in a simulation of operations using the earth model. The simulation generates well performance measures, which may be optimized depending on well performance technical limits. The optimization may be used to maximize an objective function. The system may include multiple users at the same or different locations (e.g. over a network) interacting through graphic user interfaces (GUI'"'"'s).
