This work analyzes technical-economical options to massively develop the Arcabuz-Culebra gas field located at the Burgos Basin in northeastern of Mexico. This mature field has been a gas producer since 1971 from Wilcox and Mount Selman formations, the same gas sand producers of some South Texas fields. An integrated reservoir study was conducted in order to establish the most appropriate developing plan for the Arcabuz-Culebra field according to the new production strategy of the Burgos Basin. The interpretation of 3-D seismic has improved substantially the reservoirs characterization and, along with an efficient application of hydraulic fracturing technology and the reservoir simulation of the Wilcox sands, the production has been increased dramatically. The spatial representation of hydraulic fractures in the simulation study was approximated by using a moderate local grid refinement in such a way that the quality of the numerical solution were acceptable with respect to the corresponding analytical solution during the time of interest. The study shows a procedure to analyze strategies of well spacing based on numerical simulation by reservoir sectors and the corresponding economic analysis under different well spacing. It was found that well spacing varies widely along the reservoir, and is strongly governed by local permeability, pay thickness, current pressure and associated costs. Using advanced technologies in drilling, fracturing and geosciences have proved their technical benefits in this gas field. However, results of this study demonstrate that the cost of implementing advanced technologies in drilling and hydraulic fracturing may importantly impact, under certain economic circumstances, in the well spacing strategy, and consequently in the recovery factor of these low permeability formations. The additional development plan of the Arcabuz-Culebra gas field, although profitable, resulted to be strongly dependent of new technologies and their associated costs. The field development plays a strategic role in the redevelopment of the Burgos Basin, since provides approximately one third of the production of the basin.
