Fracturing technique to minimize water production
A major problem in stimulating some formations has been the high production of formation water following fracturing treatments. This is generally considered to be due to the lack of a sufficient barrier to help prevent downward growth of the fracture from the hydrocarbon-producing zone into the water-producing interval. Thus, with conventional treatments, the undesirable water-producing zone may be fractured and propped during the fracturing treatment of the hydrocarbon-producing zone. A density-controlled fracturing technique has been developed that is capable of placing the proppant in the upper portion of a producing zone. The technique utilizes a high-density pad followed by a lower density treating fluid containing the proppant. This sequence allows the proppant to be preferentially placed in the upper portion of a vertical fracture.
