Hydraulic Fracture and Reservoir Parameters Estimation Based on Production History

Hydraulic fracturing is one of the most popular stimulation operations that are used especially for low permeability reservoirs. The technique is based on injection into the well fluid at pressure that is higher than fracturing pressure. Proppant materials are used to maintain fractures in open conditions. Therefore, evaluation of main hydraulic fracturing parameters such as length, height is a relative objective. To achieve these objectives there a lot of techniques occur. Estimation of main parameters of fracture based on production and downhole pressure data on real oil field will be done. The obtained results will be compared with real reports of service companies and analyze. The limitations of that technique are large uncertainties depending on assumptions and absence of pre-fracture data. One of the methods of estimation of hydraulic parameters estimation is based on determination of flow regime that is based on development of diagnostic log-log plots. For this purpose Rate Normalized Pressure (RNP) and equivalent material balance time were used. Production data matching in the software product has been selected as an alternative method of production data analysis. Estimation of fracture parameters based on production data does not require additional investments.
