1. A computer-based method for conducting a technical assessment phase of a brownfield assessment plan, comprising: determining an optimal set of engineering tasks to be performed in said technical assessment phase, wherein said engineering tasks to be performed are based at least on well, operations, and facilities data; performing an analysis of said well, operations, and facilities data, said analysis based on one or more of the following: well information, historical well data, and geological well data, wherein said analysis includes generating infill, injection, workover and reactivation candidates, and one or more production forecasts; determining an optimal order for performing said optimal set of engineering tasks in said technical assessment phase; and enforcing performance of said optimal set of engineering tasks in said optimal order for subsequent technical assessment phases of subsequent brownfield assessment plans; wherein said optimal set of engineering tasks and said optimal order are determined based on expert knowledge and best practices identified from performance of previous brownfield assessment plans.
