A Comparative Evaluation of Fracturing Techniques, Relating Economic Benefits to Alternative Approaches in Zonal Isolation and Selectivity

C21 A Comparative Evaluation of Fracturing Techniques Relating Economic Benefits to Alternative Approaches in Zonal Isolation and Selectivity Abstract 1 Advantages and cost / benefit evaluations associated with the decision to risk capital for the expectation of justifiable returns on fracturing and stimulation procedures have progressively improved in sophistication and accuracy of predictions. The evolution in software supporting the engineering disciplines as well as the wealth of empirical data have combined to improve returns both in procedural efficiencies and reductions of risk. This paper will review techniques relating to fracturing and stimulation procedures evolving from the basic casing frac through
