Unformatted text preview: (4) For a horizontal well drilled parallel to the minimum horizontal stress please determine (a) the break out pressure at the well (b) the break out fracture direction (c) the far field (natural) fracture direction You may neglect tensile and thermal stresses. (5) If a practical limit of 0.5" is assumed for fracture width what is (a) The radius of the fracture in feet using the Penny Model? (b) The fracture half length in feet using the KGD model? (c) The fracture height in feet using the PKN model? You may assume the net fracturing pressure is 100 psi and the rock properties are as shown in the data set....
