• Provide semi-analytical tools that capture complex multiphase flow behavior

and their application to a robust production data base (over 6000 wells) from prolific liquid plays in the USA such as the Bakken, Niobrara, Eagle Ford, Woodford, and the Permian Basin.

• Apply developed knowledge as reservoir evaluation tools to:

• Calculate fracture interference time

• Determine fracture conductivity

• Determine reservoir depletion

• Forecast fluid production

• Estimate EUR

• Identify geological, fluid, rock-fluid, completion and operational parameters and their degree of influence on production through semi-analytical and numerical multivariate analysis.

• Based on the developed theoretical framework, provide a universal fracture and well spacing optimization strategy that considers production and current economic trends such as oil prices.
