Patent ID: 7273104

Claim:
A method of treating a formation at a lateral section of a horizontal well, the lateral section having a heel, a middle, and a toe, the method comprising: pumping treatment fluid into the well such that the treatment fluid interacts with portions of the formation at the heel and toe of the lateral section; treating portions of the formation at the heel and toe of the lateral section with the pumped treatment fluid; calculating a fracture gradient representative of portions of the formation at the heel and toe of the lateral section; calculating a concentration of diverting agent to use with the treatment fluid based on the calculated fracture gradient; combining the concentration of diverting agent with treatment fluid; pumping treatment fluid with the concentration of diverting agent into the well such that the pumped treatment fluid is diverted from portions at the heel and toe of the lateral section by the diverting agent; and treating portions of the formation at the middle of the lateral section with the diverted treatment fluid.
