Abstract
A method includes gathering data about the well and the deep and tight sandstone reservoir, evaluating a diagenetic rock typing and a flow index of the reservoir using the data, and determining a first set of perforation locations based on the diagenetic rock typing and the flow index. The method also includes calibrating in-situ stresses based on the data and determining a breakdown pressure envelope and optimal perforation directions using the in-situ stresses, maximum horizontal stress direction, formation mechanical properties, and well trajectory. The method further includes narrowing the first set of perforation locations to a second set of perforation locations based on the breakdown pressure envelope, comparing the breakdown pressure envelope of the second set of perforation locations to a maximum downhole pressure to determine a perforation method, and performing a fracturing operation on the well using the second set of perforation locations, the perforation method, and the optimal perforation directions.
