Tin fouye tabankort gas field-how understanding of abvnormal fracture propagation and reservoir uncertainties led to successful hydraulic fracturing operations

摘要

Development of the TIn Fouye Tabankort gas Field, located approximately 600 miles South-Sutheast of Algoers, was initiated in 1996 with the simultaneous start-up of surface facilities construction, workovers of existing wells and drilling of new wells. The evaluation of hydraulic fracturing of new wells. The evaluation of hydraulic fracuring operation was an important sten in the formulation of the optimal development strategy for this complex Ordovician age sandstone reservoir. However production performance and hydraulic fracturing design were uncertain due to large reservoir uncertainties (heterogeneity's, kh, skin, presence of natural fissures, etc.) and doublts about the fracture heith growth behaviour.
