Proceedings Papers
Paper presented at the SPE/AAPG/SEG Unconventional Resources Technology Conference, June 17–19, 2024
Paper Number: URTEC-4029236-MS
.... Abstract Unconventional reservoirs typically decline rapidly, with wells producing 40-50% less in their second year of production, compared to their first. Therefore, it is critical to take measures to ensure maximizing the first year s production. Hydraulic fractures should propagate perpendicular...

Paper Number: URTEC-4023323-MS
... Abstract Wellbore natural fracture systems characterization is a key element to achieve the successful exploitation of tight reservoirs, where one of the dominant aspects is permeability. Carbonate reservoir fracture evaluation is challenging in terms of type, density, aperture, and extension...
