Methods comprising conveying a downhole tool within a wellbore penetrating a subterranean formation, wherein the downhole tool comprises a first pump and a second pump, and wherein at least one operational capability of the first and second pumps is substantially different. A fracture is initiated in the subterranean formation by pumping fluid into the formation using the first pump. The fracture is propagated in the subterranean formation by pumping fluid into the formation using the second pump.
