The increase in well productivity by acid ,fracturing, is displayed by the following: 1. Forming fracture, increasing the area of oil and ,gas flow, toward the well, improving oil and ,gas flow, conditions, and increasing near-wellbore flowability 2. Eliminating formation damage in the vicinity of the borehole wall 3.

Step 10: Selection of Hydraulic ,Fracturing Process,. The ,fracturing process, selected for this case is the slickwater method. This determination considers Steps 10A to 10D, and is commonly determined by a reservoir engineer. In many cases, the decision regarding water issues is made within that context.
