Abstract:
1. A method for determining fracture spacing for a first set of fractures of a wellbore, the method comprising: providing a first fracture dimension, D providing an expected second fracture dimension, D determining an approximate position of the second fracture to be formed, the approximate position being a distance, D determining an approximate position of a third fracture to be formed between the first fracture and the second fracture, the approximate position of the third fracture being a distance, D using the approximate position of the second fracture as input in a first numerical simulation to calculate a desired second fracture position; fracturing the wellbore to form the second fracture at about the desired second fracture position; using the approximate position of the third fracture as input in a second numerical simulation to calculate a desired third fracture position; and fracturing the wellbore to form the third fracture at about the desired third fracture position.
